vrPpTbclNsProvTableThis group houses all the port specific provisionable attributes
associated with Ns. These attributes influence the application of filters to
incoming and outgoing frames. SEQUENCE OF VrPpTbclNsProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.2.10 |
vrPpTbclNsProvEntryAn entry in the vrPpTbclNsProvTable. VrPpTbclNsProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.2.10.1 |
vrPpTbclNsIncomingFilterThis attribute specifies the name of the filter to be applied at the
incoming filter point.rw AsciiString .1.3.6.1.4.1.3764.1.1.30.100.3.2.2.10.1.2 |

going filter point.rw AsciiString .1.3.6.1.4.1.3764.1.1.30.100.3.2.2.10.1.3 |
vrPpTbclProvTableThis group houses all the provisionable attributes that belong to the this
group. This group of attributes is applicable to all types of bridge ports
and represent the common factor between them. These attributes
influence the working of a bridge port. SEQUENCE OF VrPpTbclProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.10 |
vrPpTbclProvEntryAn entry in the vrPpTbclProvTable. VrPpTbclProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.10.1 |
vrPpTbclTranslateIpxThis attribute specifies the type of translation to be performed on frames
carrying IPX packets. Ethernet frames carrying IPX payload could be
translated to IEEE 802.3 frames (with the same IPX payload) or vice-
versa. The main reason to do so is to allow the bridge unit to
consistently forward one type of frames carrying IPX packets.
Translations can be turned off altogether in which case the IPX frames
will pass through the bridge unit unchanged.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.10.1.1 |
vrPpTbclFragmentIpThis attribute specifies if or not outbound frames carrying IP datagrams
should be fragmented to conform to message transfer unit (mtu) sizes
dictated by the media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.10.1.2 |
vrPpTbclServiceClassThis attribute specifies if the frames should be ordered or not before they
are transmitted through a bridge port.
If this attribute has a value of ordered the received frames are ordered as
in the original message, before they are transmitted out through a bridge
port.
If it has a value of notOrdered, received then frames pass through the
bridge unit in the order they are received. This feature can be used over
multiple telecommunication links to increase data flow.
Please note that this attribute only affects link protocols and is
ineffective with lan media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.10.1.3 |
vrPpTbclConvertArpMacAddressThis attribute is indicative of the state of the MAC address format
conversion process for ARP/RARP frames. The MAC addresses may be
translated if need be from a canonical format to a non-canonical format,
based on the needs of the associated media.
If this attribute is set to a value of on then all Mac addresses will
converted if need be to suit the format of mac address, the outgoing
media will support.
If this attribute is set to a value of off no such conversion takes place.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.10.1.4 |
vrPpTbclPortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.2.10.1.5 |
vrPpTbclOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.10.1.6 |
vrPpTbclTbProvTableThis group houses all the port specific provisionable attributes that
belong to the Tb group. The Tb group is only applicable bridge port
types that operate in the TB mode. These attributes in part influence the
working of a bridge port operating in the TB mode. SEQUENCE OF VrPpTbclTbProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.11 |
vrPpTbclTbProvEntryAn entry in the vrPpTbclTbProvTable. VrPpTbclTbProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.11.1 |
vrPpTbclSecureOptionThis attribute specifies whether the port secure feature is enabled. The
secure feature, if enabled causes the following things to happen:
a) disallows dynamic learning,
b) disallows frames to be forwarded that do not satisfy the following
condition: the mac address of the source should be found in the
forwarding table and the destination mac address of the frame should
also be found in the forwarding table. In addition to this, the port the
frame was received on should figure as the in port, given the destination
mac address found in the frame.
c) disallows frames to be forwarded if the allowed to go port map for the
destination mac address is empty.
This feature in effect allows the user to choose the hosts that can
generate traffic and the hosts that can receive traffic through this bridge
unit.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.11.1.1 |
vrPpTbclStpProvTableThis group houses all the port specific provisionable attributes that
belong to the Stp group. The Stp group is applicable to all the bridge
ports that participate in the spanning tree protocol. These attributes
influence the participation of the bridge port in the spanning tree
protocol. SEQUENCE OF VrPpTbclStpProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.12 |
vrPpTbclStpProvEntryAn entry in the vrPpTbclStpProvTable. VrPpTbclStpProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.12.1 |
vrPpTbclAdminStatusThis attribute defines the current administrative state for this component.
enabled indicates that the component is available for operation. disabled
indicates the component is unavailable for operation.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.12.1.1 |
vrPpTbclPortStateStpControlThis attribute specifies whether or not spanning tree protocol state for
this bridge port is controlled by the spanning tree protocol. In essence it
indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an
action on your network topology.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.12.1.2 |
vrPpTbclStpTypeProvThis attribute specifies the type of spanning tree protocol the port is
participating in. A bridge port could participate in either the ieee8021
spanning tree protocol or the dec spanning tree protocol. If the value of
the attribute protocolSpec in the SpanningTreeProtocol component,
provisioned under the TransparentBridge component is in conflict with
the value of this attribute, the value of the protocolSpec attribute will
prevail. Prevailing stp type is reflected in the value of the attribute
stpTypeOper.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.12.1.3 |
vrPpTbclPortPriorityThis attribute specifies the value for port priority, which is contained in
the first octet of the port identifier. Valid values are as follows:
1) 0..255 for stp type DEC and
2) 0..65535 for stp type IEEE.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.2.12.1.4 |
vrPpTbclPathCostThis attribute specifies the contribution of this port, to all the paths to the
root bridge that include this port. Please note that the value of the
attribute pathCostMethod is applied only when the value of the attribute
pathCostMethod is set to on and is ignored if otherwise.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.2.12.1.5 |
vrPpTbclPathCostMethodThis attribute specifies the method used by the bridging logic, to
calculate the path cost to the bridge considered to be the root bridge in
the spanning tree topology. This attribute should be set to off before
attempting to provision a value for pathCostProv.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.12.1.6 |
vrPpTbclDIProvTableThis group houses all the provisionable, domain specific attributes for a
non-encapsulating bridge port. SEQUENCE OF VrPpTbclDIProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.13 |
vrPpTbclDIProvEntryAn entry in the vrPpTbclDIProvTable. VrPpTbclDIProvEntry .1.3.6.1.4.1.3764.1.1.30.100.3.2.13.1 |
vrPpTbclDomainNumThis attribute specifies the domain number associated with this bridge
port. Domain numbers are used for confining frames to a domain.
Domain based filtering provides a complete segregation of traffic based
on domain number associated with frames. There can exist only sixteen
domains when a spanning tree is desired specific to each domain. When
there is only a single spanning tree spanning all the domains the
maximum number of domains possible are 4294967293.
This attribute is of no relevance when associated with backbone bridge
port. Its value is ignored in such a situation.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.2.13.1.1 |
vrPpTbclPreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.13.1.2 |
vrPpTbclStateTableThis group contains the three OSI State attributes. The descriptions
generically indicate what each state attribute implies about the

turn implies the format of frames, this bridge port can process and
forward.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.16.1.5 |
vrPpTbclBridgePortConfigThis attribute specifies the bridge port's configuration. It indicates if the
bridge port is operating as an access port or as a backbone port. An
access bridge port does not encapsulate a MAC frame and does not
preserve domain information in the encapsulation, whereas a backbone
bridge port encapsulates the MAC frame and optionally preserves
domain information in the encapsulated frame.A backbone bridge port
is typically used to transport frames across a high bandwidth backbone
network to another bridge unit for further processing/forwarding of the
frame.ro Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.2.16.1.6 |
vrPpTbclBridgePortTypeThis attribute specifies the type of bridge port that was provisioned. It
takes into consideration the bridgingMode, bridgePortConfig and the

vrPpTbclDelayExceededDiscardsThis attribute is indicative of the number of frames that were discarded
because the time taken to process these frames exceeded the transit
delay allowed for this bridge unit. This attribute is not supported by
bridging and will always have a value of 0.ro Counter32 .1.3.6.1.4.1.3764.1.1.30.100.3.2.16.1.10 |
vrPpTbclMtuExceededDiscardsThis attribute is indicative of the number of frames discarded because
the size of the out bound frame exceeded the message transfer unit (mtu)
allowed for the bridge port. Note that this counter only refers to the
outbound frames for this bridge port. This counter wraps around its
maximum value of 4294967295.
This counter is influenced by the attribute fragmentIp. This counter is
incremented when the a frame larger than the mtu allowed is
encountered and cannot be fragmented. If this counter is increasing
steadily, it might be useful to set the value of the attribute fragmentIp to
a value of on.ro Counter32 .1.3.6.1.4.1.3764.1.1.30.100.3.2.16.1.11 |

vrPpTbclBadVerifyDiscardsThis attribute is indicative of the number of incoming frames that were
discarded because:
a) the value of the secureOption attribute was set to on and
b) it is not allowed to receive frames originating from the mac address
found in the source address field of the frame (source mac address look
up in the forwarding table failed.) on this bridge port.
c) for the destination mac address found in the frame, the port the frame
was received on does not appear as in port in the corresponding static
table entry.
Permission to receive frames from a mac address is granted via the static
table entries.
This attribute, badVerifyDiscards, is directly influenced by:
1. secureOption and
2. the static table entries.

vrPpTbclUnicastNoMatchesThis attribute is indicative of the number frames discarded because the
MAC address found in the destination field did not match the local MAC
address of the bridge port. This counter is only applicable for the
protocols that are being routed currently.This counter wraps around its
maximum value of 4294967295.ro Counter32 .1.3.6.1.4.1.3764.1.1.30.100.3.2.17.1.4 |
vrPpTbclStaticEntryDiscardsThis attribute is indicative of the number of frames that were discarded
because of the following two reasons:
a) there was no entry for the 'allowed to go' field in the static table
entry, where the input port is this bridge port.
b) for spanning tree bpdus that are locally processed.
This counter wraps around its maximum value of 4294967295.
It might prove useful to check the static table entry corresponding to the
bridge port in question, if this counter consistently displays a high value.
Ideally this counter should be as low as possible.ro Counter32 .1.3.6.1.4.1.3764.1.1.30.100.3.2.17.1.5 |
vrPpTbclDynamicEntryDiscardsThis attribute is indicative of the number of incoming frames that
a) were discarded because of the fact that the bridge port, the frame is to

vrPpFddiETBTranslateIpxThis attribute specifies the type of translation to be performed on frames
carrying IPX packets. Ethernet frames carrying IPX payload could be
translated to IEEE 802.3 frames (with the same IPX payload) or vice-
versa. The main reason to do so is to allow the bridge unit to
consistently forward one type of frames carrying IPX packets.

vrPpFddiETBPortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.3.10.1.5 |
vrPpFddiETBOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.3.10.1.6 |

vrPpFddiETBSecureOptionThis attribute specifies whether the port secure feature is enabled. The
secure feature, if enabled causes the following things to happen:
a) disallows dynamic learning,
b) disallows frames to be forwarded that do not satisfy the following
condition: the mac address of the source should be found in the
forwarding table and the destination mac address of the frame should
also be found in the forwarding table. In addition to this, the port the
frame was received on should figure as the in port, given the destination
mac address found in the frame.
c) disallows frames to be forwarded if the allowed to go port map for the
destination mac address is empty.
This feature in effect allows the user to choose the hosts that can

vrPpFddiETBPortStateStpControlThis attribute specifies whether or not spanning tree protocol state for
this bridge port is controlled by the spanning tree protocol. In essence it
indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an
action on your network topology.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.3.12.1.2 |
vrPpFddiETBStpTypeProvThis attribute specifies the type of spanning tree protocol the port is

vrPpFddiETBDomainNumThis attribute specifies the domain number associated with this bridge
port. Domain numbers are used for confining frames to a domain.
Domain based filtering provides a complete segregation of traffic based
on domain number associated with frames. There can exist only sixteen
domains when a spanning tree is desired specific to each domain. When
there is only a single spanning tree spanning all the domains the
maximum number of domains possible are 4294967293.
This attribute is of no relevance when associated with backbone bridge
port. Its value is ignored in such a situation.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.3.13.1.1 |
vrPpFddiETBPreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.3.13.1.2 |

vrPpFddiETBBridgePortConfigThis attribute specifies the bridge port's configuration. It indicates if the
bridge port is operating as an access port or as a backbone port. An
access bridge port does not encapsulate a MAC frame and does not
preserve domain information in the encapsulation, whereas a backbone
bridge port encapsulates the MAC frame and optionally preserves
domain information in the encapsulated frame.A backbone bridge port
is typically used to transport frames across a high bandwidth backbone
network to another bridge unit for further processing/forwarding of the

discarded because:
a) the value of the secureOption attribute was set to on and
b) it is not allowed to receive frames originating from the mac address
found in the source address field of the frame (source mac address look
up in the forwarding table failed.) on this bridge port.
c) for the destination mac address found in the frame, the port the frame
was received on does not appear as in port in the corresponding static

vrPpTbpTranslateIpxThis attribute specifies the type of translation to be performed on frames
carrying IPX packets. Ethernet frames carrying IPX payload could be
translated to IEEE 802.3 frames (with the same IPX payload) or vice-
versa. The main reason to do so is to allow the bridge unit to
consistently forward one type of frames carrying IPX packets.
Translations can be turned off altogether in which case the IPX frames
will pass through the bridge unit unchanged.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.4.10.1.1 |

vrPpTbpServiceClassThis attribute specifies if the frames should be ordered or not before they
are transmitted through a bridge port.
If this attribute has a value of ordered the received frames are ordered as
in the original message, before they are transmitted out through a bridge
port.
If it has a value of notOrdered, received then frames pass through the
bridge unit in the order they are received. This feature can be used over
multiple telecommunication links to increase data flow.

converted if need be to suit the format of mac address, the outgoing
media will support.

vrPpTbpPortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.4.10.1.5 |
vrPpTbpOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.4.10.1.6 |

vrPpTbpSecureOptionThis attribute specifies whether the port secure feature is enabled. The
secure feature, if enabled causes the following things to happen:
a) disallows dynamic learning,
b) disallows frames to be forwarded that do not satisfy the following
condition: the mac address of the source should be found in the
forwarding table and the destination mac address of the frame should
also be found in the forwarding table. In addition to this, the port the
frame was received on should figure as the in port, given the destination
mac address found in the frame.
c) disallows frames to be forwarded if the allowed to go port map for the
destination mac address is empty.
This feature in effect allows the user to choose the hosts that can

vrPpTbpPortStateStpControlThis attribute specifies whether or not spanning tree protocol state for
this bridge port is controlled by the spanning tree protocol. In essence it
indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an
action on your network topology.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.4.12.1.2 |
vrPpTbpStpTypeProvThis attribute specifies the type of spanning tree protocol the port is
participating in. A bridge port could participate in either the ieee8021
spanning tree protocol or the dec spanning tree protocol. If the value of
the attribute protocolSpec in the SpanningTreeProtocol component,
provisioned under the TransparentBridge component is in conflict with

vrPpTbpDomainNumThis attribute specifies the domain number associated with this bridge
port. Domain numbers are used for confining frames to a domain.
Domain based filtering provides a complete segregation of traffic based
on domain number associated with frames. There can exist only sixteen
domains when a spanning tree is desired specific to each domain. When
there is only a single spanning tree spanning all the domains the
maximum number of domains possible are 4294967293.
This attribute is of no relevance when associated with backbone bridge
port. Its value is ignored in such a situation.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.4.13.1.1 |
vrPpTbpPreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.4.13.1.2 |

conversion process for ARP/RARP frames. The MAC addresses may be
translated if need be from a canonical format to a non-canonical format,
based on the needs of the associated media.
If this attribute is set to a value of on then all Mac addresses will
converted if need be to suit the format of mac address, the outgoing
media will support.
If this attribute is set to a value of off no such conversion takes place.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.8.10.1.4 |
vrPpSrBpPortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.8.10.1.5 |
vrPpSrBpOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.8.10.1.6 |

vrPpSrBpPortStateStpControlThis attribute specifies whether or not spanning tree protocol state for
this bridge port is controlled by the spanning tree protocol. In essence it
indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an

vrPpSrBpDomainNumThis attribute specifies the domain number associated with this bridge
port. Domain numbers are used for confining frames to a domain.
Domain based filtering provides a complete segregation of traffic based
on domain number associated with frames. There can exist only sixteen
domains when a spanning tree is desired specific to each domain. When
there is only a single spanning tree spanning all the domains the
maximum number of domains possible are 4294967293.

vrPpSrBpPreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.8.13.1.2 |

vrPpSrtBpTranslateIpxThis attribute specifies the type of translation to be performed on frames
carrying IPX packets. Ethernet frames carrying IPX payload could be
translated to IEEE 802.3 frames (with the same IPX payload) or vice-
versa. The main reason to do so is to allow the bridge unit to
consistently forward one type of frames carrying IPX packets.
Translations can be turned off altogether in which case the IPX frames
will pass through the bridge unit unchanged.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.9.10.1.1 |

vrPpSrtBpServiceClassThis attribute specifies if the frames should be ordered or not before they
are transmitted through a bridge port.
If this attribute has a value of ordered the received frames are ordered as
in the original message, before they are transmitted out through a bridge
port.
If it has a value of notOrdered, received then frames pass through the
bridge unit in the order they are received. This feature can be used over
multiple telecommunication links to increase data flow.

ineffective with lan media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.9.10.1.3 |
vrPpSrtBpConvertArpMacAddressThis attribute is indicative of the state of the MAC address format
conversion process for ARP/RARP frames. The MAC addresses may be
translated if need be from a canonical format to a non-canonical format,
based on the needs of the associated media.
If this attribute is set to a value of on then all Mac addresses will
converted if need be to suit the format of mac address, the outgoing
media will support.
If this attribute is set to a value of off no such conversion takes place.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.9.10.1.4 |
vrPpSrtBpPortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.9.10.1.5 |
vrPpSrtBpOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.9.10.1.6 |

vrPpSrtBpSecureOptionThis attribute specifies whether the port secure feature is enabled. The
secure feature, if enabled causes the following things to happen:
a) disallows dynamic learning,
b) disallows frames to be forwarded that do not satisfy the following
condition: the mac address of the source should be found in the
forwarding table and the destination mac address of the frame should
also be found in the forwarding table. In addition to this, the port the
frame was received on should figure as the in port, given the destination
mac address found in the frame.
c) disallows frames to be forwarded if the allowed to go port map for the
destination mac address is empty.
This feature in effect allows the user to choose the hosts that can

vrPpSrtBpPortStateStpControlThis attribute specifies whether or not spanning tree protocol state for
this bridge port is controlled by the spanning tree protocol. In essence it
indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an
action on your network topology.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.9.12.1.2 |
vrPpSrtBpStpTypeProvThis attribute specifies the type of spanning tree protocol the port is

spanning tree protocol or the dec spanning tree protocol. If the value of
the attribute protocolSpec in the SpanningTreeProtocol component,
provisioned under the TransparentBridge component is in conflict with
the value of this attribute, the value of the protocolSpec attribute will

vrPpSrtBpDomainNumThis attribute specifies the domain number associated with this bridge
port. Domain numbers are used for confining frames to a domain.
Domain based filtering provides a complete segregation of traffic based
on domain number associated with frames. There can exist only sixteen
domains when a spanning tree is desired specific to each domain. When
there is only a single spanning tree spanning all the domains the
maximum number of domains possible are 4294967293.
This attribute is of no relevance when associated with backbone bridge
port. Its value is ignored in such a situation.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.9.13.1.1 |
vrPpSrtBpPreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.9.13.1.2 |

vrPpSrseTranslateIpxThis attribute specifies the type of translation to be performed on frames
carrying IPX packets. Ethernet frames carrying IPX payload could be
translated to IEEE 802.3 frames (with the same IPX payload) or vice-
versa. The main reason to do so is to allow the bridge unit to
consistently forward one type of frames carrying IPX packets.

vrPpSrsePortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.10.10.1.5 |
vrPpSrseOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.10.10.1.6 |

this bridge port is controlled by the spanning tree protocol. In essence it
indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an

vrPpSrseDomainNumThis attribute specifies the domain number associated with this bridge
port. Domain numbers are used for confining frames to a domain.
Domain based filtering provides a complete segregation of traffic based
on domain number associated with frames. There can exist only sixteen
domains when a spanning tree is desired specific to each domain. When
there is only a single spanning tree spanning all the domains the
maximum number of domains possible are 4294967293.
This attribute is of no relevance when associated with backbone bridge
port. Its value is ignored in such a situation.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.10.13.1.1 |
vrPpSrsePreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.10.13.1.2 |

vrPpTbseTranslateIpxThis attribute specifies the type of translation to be performed on frames
carrying IPX packets. Ethernet frames carrying IPX payload could be
translated to IEEE 802.3 frames (with the same IPX payload) or vice-
versa. The main reason to do so is to allow the bridge unit to
consistently forward one type of frames carrying IPX packets.
Translations can be turned off altogether in which case the IPX frames
will pass through the bridge unit unchanged.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.11.10.1.1 |
vrPpTbseFragmentIpThis attribute specifies if or not outbound frames carrying IP datagrams
should be fragmented to conform to message transfer unit (mtu) sizes
dictated by the media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.11.10.1.2 |
vrPpTbseServiceClassThis attribute specifies if the frames should be ordered or not before they
are transmitted through a bridge port.
If this attribute has a value of ordered the received frames are ordered as
in the original message, before they are transmitted out through a bridge
port.
If it has a value of notOrdered, received then frames pass through the
bridge unit in the order they are received. This feature can be used over
multiple telecommunication links to increase data flow.
Please note that this attribute only affects link protocols and is
ineffective with lan media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.11.10.1.3 |
vrPpTbseConvertArpMacAddressThis attribute is indicative of the state of the MAC address format
conversion process for ARP/RARP frames. The MAC addresses may be
translated if need be from a canonical format to a non-canonical format,
based on the needs of the associated media.
If this attribute is set to a value of on then all Mac addresses will
converted if need be to suit the format of mac address, the outgoing
media will support.
If this attribute is set to a value of off no such conversion takes place.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.11.10.1.4 |
vrPpTbsePortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.11.10.1.5 |
vrPpTbseOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.11.10.1.6 |

vrPpTbseSecureOptionThis attribute specifies whether the port secure feature is enabled. The
secure feature, if enabled causes the following things to happen:
a) disallows dynamic learning,
b) disallows frames to be forwarded that do not satisfy the following
condition: the mac address of the source should be found in the
forwarding table and the destination mac address of the frame should
also be found in the forwarding table. In addition to this, the port the
frame was received on should figure as the in port, given the destination
mac address found in the frame.
c) disallows frames to be forwarded if the allowed to go port map for the
destination mac address is empty.
This feature in effect allows the user to choose the hosts that can
generate traffic and the hosts that can receive traffic through this bridge
unit.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.11.11.1.1 |

vrPpTbsePortStateStpControlThis attribute specifies whether or not spanning tree protocol state for
this bridge port is controlled by the spanning tree protocol. In essence it
indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an
action on your network topology.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.11.12.1.2 |
vrPpTbseStpTypeProvThis attribute specifies the type of spanning tree protocol the port is
participating in. A bridge port could participate in either the ieee8021
spanning tree protocol or the dec spanning tree protocol. If the value of
the attribute protocolSpec in the SpanningTreeProtocol component,
provisioned under the TransparentBridge component is in conflict with
the value of this attribute, the value of the protocolSpec attribute will
prevail. Prevailing stp type is reflected in the value of the attribute

vrPpTbseDomainNumThis attribute specifies the domain number associated with this bridge
port. Domain numbers are used for confining frames to a domain.
Domain based filtering provides a complete segregation of traffic based
on domain number associated with frames. There can exist only sixteen
domains when a spanning tree is desired specific to each domain. When
there is only a single spanning tree spanning all the domains the
maximum number of domains possible are 4294967293.
This attribute is of no relevance when associated with backbone bridge
port. Its value is ignored in such a situation.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.11.13.1.1 |
vrPpTbsePreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.11.13.1.2 |

vrPpSrsgTranslateIpxThis attribute specifies the type of translation to be performed on frames
carrying IPX packets. Ethernet frames carrying IPX payload could be
translated to IEEE 802.3 frames (with the same IPX payload) or vice-
versa. The main reason to do so is to allow the bridge unit to
consistently forward one type of frames carrying IPX packets.
Translations can be turned off altogether in which case the IPX frames
will pass through the bridge unit unchanged.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.12.10.1.1 |

vrPpSrsgServiceClassThis attribute specifies if the frames should be ordered or not before they
are transmitted through a bridge port.
If this attribute has a value of ordered the received frames are ordered as
in the original message, before they are transmitted out through a bridge
port.
If it has a value of notOrdered, received then frames pass through the
bridge unit in the order they are received. This feature can be used over
multiple telecommunication links to increase data flow.

translated if need be from a canonical format to a non-canonical format,
based on the needs of the associated media.
If this attribute is set to a value of on then all Mac addresses will
converted if need be to suit the format of mac address, the outgoing
media will support.
If this attribute is set to a value of off no such conversion takes place.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.12.10.1.4 |
vrPpSrsgPortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.12.10.1.5 |
vrPpSrsgOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.12.10.1.6 |

vrPpSrsgPortStateStpControlThis attribute specifies whether or not spanning tree protocol state for
this bridge port is controlled by the spanning tree protocol. In essence it
indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an
action on your network topology.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.12.12.1.2 |
vrPpSrsgStpTypeProvThis attribute specifies the type of spanning tree protocol the port is
participating in. A bridge port could participate in either the ieee8021
spanning tree protocol or the dec spanning tree protocol. If the value of
the attribute protocolSpec in the SpanningTreeProtocol component,
provisioned under the TransparentBridge component is in conflict with
the value of this attribute, the value of the protocolSpec attribute will

vrPpSrsgDomainNumThis attribute specifies the domain number associated with this bridge
port. Domain numbers are used for confining frames to a domain.
Domain based filtering provides a complete segregation of traffic based
on domain number associated with frames. There can exist only sixteen
domains when a spanning tree is desired specific to each domain. When
there is only a single spanning tree spanning all the domains the
maximum number of domains possible are 4294967293.
This attribute is of no relevance when associated with backbone bridge
port. Its value is ignored in such a situation.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.12.13.1.1 |
vrPpSrsgPreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.12.13.1.2 |

vrPpTbsgTranslateIpxThis attribute specifies the type of translation to be performed on frames
carrying IPX packets. Ethernet frames carrying IPX payload could be
translated to IEEE 802.3 frames (with the same IPX payload) or vice-
versa. The main reason to do so is to allow the bridge unit to
consistently forward one type of frames carrying IPX packets.
Translations can be turned off altogether in which case the IPX frames
will pass through the bridge unit unchanged.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.13.10.1.1 |

dictated by the media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.13.10.1.2 |
vrPpTbsgServiceClassThis attribute specifies if the frames should be ordered or not before they
are transmitted through a bridge port.
If this attribute has a value of ordered the received frames are ordered as
in the original message, before they are transmitted out through a bridge
port.
If it has a value of notOrdered, received then frames pass through the
bridge unit in the order they are received. This feature can be used over
multiple telecommunication links to increase data flow.

translated if need be from a canonical format to a non-canonical format,
based on the needs of the associated media.
If this attribute is set to a value of on then all Mac addresses will
converted if need be to suit the format of mac address, the outgoing
media will support.
If this attribute is set to a value of off no such conversion takes place.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.13.10.1.4 |
vrPpTbsgPortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.13.10.1.5 |
vrPpTbsgOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.13.10.1.6 |

vrPpTbsgSecureOptionThis attribute specifies whether the port secure feature is enabled. The
secure feature, if enabled causes the following things to happen:
a) disallows dynamic learning,
b) disallows frames to be forwarded that do not satisfy the following
condition: the mac address of the source should be found in the
forwarding table and the destination mac address of the frame should
also be found in the forwarding table. In addition to this, the port the
frame was received on should figure as the in port, given the destination
mac address found in the frame.
c) disallows frames to be forwarded if the allowed to go port map for the
destination mac address is empty.
This feature in effect allows the user to choose the hosts that can
generate traffic and the hosts that can receive traffic through this bridge

vrPpTbsgPortStateStpControlThis attribute specifies whether or not spanning tree protocol state for
this bridge port is controlled by the spanning tree protocol. In essence it
indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an
action on your network topology.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.13.12.1.2 |
vrPpTbsgStpTypeProvThis attribute specifies the type of spanning tree protocol the port is
participating in. A bridge port could participate in either the ieee8021
spanning tree protocol or the dec spanning tree protocol. If the value of
the attribute protocolSpec in the SpanningTreeProtocol component,
provisioned under the TransparentBridge component is in conflict with
the value of this attribute, the value of the protocolSpec attribute will

vrPpTbsgDomainNumThis attribute specifies the domain number associated with this bridge
port. Domain numbers are used for confining frames to a domain.
Domain based filtering provides a complete segregation of traffic based
on domain number associated with frames. There can exist only sixteen
domains when a spanning tree is desired specific to each domain. When
there is only a single spanning tree spanning all the domains the
maximum number of domains possible are 4294967293.
This attribute is of no relevance when associated with backbone bridge
port. Its value is ignored in such a situation.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.13.13.1.1 |
vrPpTbsgPreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.13.13.1.2 |

bridge port is operating as an access port or as a backbone port. An
access bridge port does not encapsulate a MAC frame and does not
preserve domain information in the encapsulation, whereas a backbone
bridge port encapsulates the MAC frame and optionally preserves
domain information in the encapsulated frame.A backbone bridge port
is typically used to transport frames across a high bandwidth backbone

vrPpSrclTranslateIpxThis attribute specifies the type of translation to be performed on frames
carrying IPX packets. Ethernet frames carrying IPX payload could be
translated to IEEE 802.3 frames (with the same IPX payload) or vice-
versa. The main reason to do so is to allow the bridge unit to
consistently forward one type of frames carrying IPX packets.

vrPpSrclPortNumThis attribute is indicative of the unique number assigned to the bridge
port. It is used for SNMP management of this bridge port and in
spanning tree as an identifier this bridge port.
Notes regarding portNum:
Escape routines exist for initializing, copying, and deleting port
numbers. This is necessary because SNMP requires a unique port
instance identifier. The initPortNum escape routine sets the port number
to a value in the range 1-255 for this purpose. The setCopiedPortNum
escape routine exists to maintain the uniqueness of the port number in
cases when one port is copied to another. When a bridge port is deleted,
the releasePortNum escape routine places the port number being
released into a pending deletion state. This is because the port number
cannot be re-allocated until the port is truely deleted in the current view.
This is necessary since there is no guarantee of order when processing
changes to multiple protocol ports so without the pending deletion state,
the same port number could be temporarily assigned to two ports for a
short period of time.
The portNum is set as component critical since bridging also uses the
port number as a key for indexing into its data structures. If a port is
deleted then re-added under the same protocol port, CAS treats the
change as a SET to the portNum attribute.ro Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.14.10.1.5 |
vrPpSrclOutboundFrameMediaTypeThis attribute specifies the media type the frame must be in before it is
to be forwarded over the outbound supported WAN Bridge Protocol
Port. The attribute only applies to outbound Bridge Protocol Port.
For supported bridge ports, if the attribute value remains set to the
default value of unaltered then there will be no frame conversion. When
the value is set to the value ethernetConv then all frames being
forwarded out the outbound WAN Port will be converted to ethernet
before forwarding takes place. The only outbound WAN medias that
currently support conversion are: FR (Frame Relay) and VNS. All other
medias will fail the Bridge Port semantic check when attempts are made
to alter this attribute.
The following is an example of what the user may be able to do. Frames
originating from a Token Ring are to be flooded out onto another Token
Ring and a Frame Relay Port. The token ring Outbound port performs
no translation, yet the FR Port has the outboundFrameMediaType
attribute set to ethernetConv which results in the frame being translated
into Ethernet format from Token Ring format before Frame Relay does
its encapsulation and transmits over the FR port.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.14.10.1.6 |

indicates the participation of this bridge port in the spanning tree
protocol, by accepting and acting on received bridge protocol data units
and by sending out the same.
on signifies that this bridge port's spanning tree port state is controlled
by the spanning tree protocol.
A value of off signifies that the spanning tree port state of this bridge
port is unaffected by the spanning tree protocol. This in effect puts the
bridge port out of reach of the spanning tree protocol and in the
forwarding state. Care should be taken while assigning a value of off to
this attribute, as this might cause network loops. Please do not set this
attribute to off unless you are absolutely sure about the effect of such an

maximum number of domains possible are 4294967293.
This attribute is of no relevance when associated with backbone bridge
port. Its value is ignored in such a situation.rw Unsigned32 .1.3.6.1.4.1.3764.1.1.30.100.3.14.13.1.1 |
vrPpSrclPreserveDomainThis attribute specifies if the domain information should be preserved or
embedded in the frame header. This attribute applies only to backbone
ports and does not affect the access bridge ports. By setting this attribute
to a value of on, domain information could be preserved in frames being
tunnelled across the a backbone, so that this information can be
deciphered at the other end of the backbone tunnel. This preserves the
integrity of the domains thus preventing domain breaches while
tunnelling frames across backbone network.
If the value of this attribute is set to off then domain information is not
preserved in the header of the frames tunnelling through the backbone.
This eliminates the overhead incurred to preserve domain information
across the backbone while tunnelling frames across it.
Preserve domain is relevant when used in conjunction with the following
media: FDDI, ATM MPE, Frame Relay and PPP. It is ignored when
used with other types of media.rw Enumeration .1.3.6.1.4.1.3764.1.1.30.100.3.14.13.1.2 |
