usrBRBase OBJECT IDENTIFIER .1.3.6.1.4.1.429.4.14.1 |
RFC1155-SMI Unknown .1.3.6.1.4.1.429.4.14.1 |
usrBRBaseBridgeAddressThe MAC address used by this bridge when it must
be referred to in a unique fashion. It is
recommended that this be the numerically smallest
MAC address of all ports that belong to this
bridge. However it is only required to be unique.
When concatenated with usrBRStpPriority a unique
BridgeIdentifier is formed which is used in the
Spanning Tree Protocol.ro MacAddress (SNMPv2-TC) .1.3.6.1.4.1.429.4.14.1.1 |
usrBRBaseNumPortsThe number of ports controlled by this bridging
entity.ro INTEGER .1.3.6.1.4.1.429.4.14.1.2 |
usrBRBaseTypeIndicates what type of bridging this bridge can
perform. If a bridge is actually performing a
certain type of bridging this will be indicated by
entries in the port table for the given type.ro Enumeration .1.3.6.1.4.1.429.4.14.1.3 |
usrBRBaseStaticMacsOnlyIndicates whether the bridge will forward
all (non-local) packets or just those to and
from the stations whose MAC addresses are
specified in the Access List (BRStaticTable).rw Enumeration .1.3.6.1.4.1.429.4.14.1.4 |
usrBRBaseAgingTimeThe timeout period in seconds for aging out
dynamically learned forwarding information.
802.1D-1990 recommends a default of 300 seconds.rw INTEGER .1.3.6.1.4.1.429.4.14.1.5 |
usrBRBaseLearnedEntryDiscardsThe total number of Forwarding Database entries,
which have been or would have been learnt, but
have been discarded due to a lack of space to
store them in the Forwarding Database. If this
counter is increasing, it indicates that the
Forwarding Database is regularly becoming full (a
condition which has unpleasant performance effects
on the subnetwork). If this counter has a
significant value but is not presently increasing,
it indicates that the problem has been occurring
but is not persistent.ro Counter .1.3.6.1.4.1.429.4.14.1.6 |
usrBRBaseCfgFileNameThe name of a ConfigFile to read/write
permanent database records. If the value of this
object is an empty string, then the Bridge process
uses the default name `@file://BridgeFile.cfg'.rw DisplayString (SNMPv2-TC) .1.3.6.1.4.1.429.4.14.1.7 |
usrBRBaseCFMSaveStatusSetting the value of this object to `save'
causes the values of the Bridge Base Group
entries to be written out to the current Bridge
config file. While the new config file is being
written, the Bridge process will set the value
of this flag set to `saving''. Any attempts to set
the value while it is not `normal' (i.e. the file
is currently being written to the config file)
while result in a badValue error being returned.
Setting the value to `normal' will result in no
action.rw UsrConfigStatus .1.3.6.1.4.1.429.4.14.1.8 |
usrBRBaseWanToWanForwardingIndicates whether the bridge will forward
packets received on a wide area port
to other wide area ports.rw Enumeration .1.3.6.1.4.1.429.4.14.1.9 |

to this port.ro INTEGER .1.3.6.1.4.1.429.4.14.1.10.1.3 |
usrBRBasePortInFramesThe number of frames that have been received by
this port from its segment. Note that a frame
received on the interface corresponding to this
port is only counted by this object if and only if
it is for a protocol being processed by the local
bridging function, including bridge management
frames.ro Counter .1.3.6.1.4.1.429.4.14.1.10.1.4 |
usrBRBasePortOutFramesThe number of frames that have been transmitted
by this port to its segment. Note that a frame
transmitted on the interface corresponding to this
port is only counted by this object if and only if
it is for a protocol being processed by the local
bridging function, including bridge management
frames.ro Counter .1.3.6.1.4.1.429.4.14.1.10.1.5 |
usrBRBasePortInDiscardsCount of valid frames received which were
discarded (i.e., filtered) by the Forwarding
Process.ro Counter .1.3.6.1.4.1.429.4.14.1.10.1.6 |
usrBRBaseBridgeFirewallModeThe Firewall mode determines how the bridge forwards
packets when the Platform is enabled as a Bridge/Router.

forwarded over bridge ports. If set to 1, only unicasts
not destined to the BRouter's are forwarded, and if set
to 2, pkts defined in (1) and Broadcasts are forwarded.rw Enumeration .1.3.6.1.4.1.429.4.14.1.11 |

information learned from the network on any port
before it is discarded, in units of hundredths of
a second. This is the actual value that this
bridge is currently using.ro Timeout .1.3.6.1.4.1.429.4.14.2.9 |
usrBRStpHelloTimeThe amount of time between the transmission of
Configuration bridge PDUs by this node on any port
when it is the root of the spanning tree or trying
to become so, in units of hundredths of a second.
This is the actual value that this bridge is
currently using.ro Timeout .1.3.6.1.4.1.429.4.14.2.10 |
usrBRStpHoldTimeThis time value determines the interval length
during which no more than two Configuration bridge
PDUs shall be transmitted by this node, in units
of hundredths of a second.ro INTEGER .1.3.6.1.4.1.429.4.14.2.11 |
usrBRStpForwardDelayThis time value, measured in units of hundredths
of a second, controls how fast a port changes its
spanning state when moving towards the Forwarding
state. The value determines how long the port
stays in each of the Listening and Learning
states, which precede the Forwarding state. This
value is also used, when a topology change has
been detected and is underway, to age all dynamic
entries in the Forwarding Database. [Note that
this value is the one that this bridge is
currently using, in contrast to
usrBRStpBridgeForwardDelay which is the value that
this bridge and all others would start using
if/when this bridge were to become the root.]ro Timeout .1.3.6.1.4.1.429.4.14.2.12 |
usrBRStpBridgeMaxAgeThe value that all bridges use for MaxAge when
this bridge is acting as the root. Note that
802.1D-1990 specifies that the range for this
parameter is related to the value of
usrBRStpBridgeHelloTime. The granularity of this
timer is specified by 802.1D-1990 to be 1 second.
An agent may return a badValue error if a set is
attempted to a value which is not a whole number
of seconds.rw Timeout .1.3.6.1.4.1.429.4.14.2.13 |
usrBRStpBridgeHelloTimeThe value that all bridges use for HelloTime when
this bridge is acting as the root. The
granularity of this timer is specified by 802.1D-
1990 to be 1 second. An agent may return a

which is not a whole number of seconds.rw Timeout .1.3.6.1.4.1.429.4.14.2.14 |
usrBRStpBridgeForwardDelayThe value that all bridges use for ForwardDelay
when this bridge is acting as the root. Note that
802.1D-1990 specifies that the range for this
parameter is related to the value of
usrBRStpBridgeMaxAge. The granularity of this
timer is specified by 802.1D-1990 to be 1 second.
An agent may return a badValue error if a set is
attempted to a value which is not a whole number
of seconds.rw Timeout .1.3.6.1.4.1.429.4.14.2.15 |

usrBRTpFdbPortEither the value '0', or the port number of the
port on which a frame having a source address
equal to the value of the corresponding instance
of usrBRTpFdbAddress has been seen. A value of
'0' indicates that the port number has not been
learned but that the bridge does have some
forwarding/filtering information about this
address (e.g. in the usrBRStaticTable).

value to this object whenever it is learned even
for addresses for which the corresponding value of
usrBRTpFdbStatus is not learned(3).ro INTEGER .1.3.6.1.4.1.429.4.14.3.1.1.2 |
usrBRTpFdbStatusThe status of this entry. The meanings of the
values are:
other(1) : none of the following. This would
include the case where some other
MIB object (not the corresponding
instance of usrBRTpFdbPort, nor an
entry in the usrBRStaticTable) is
being used to determine if and how
frames addressed to the value of
the corresponding instance of
usrBRTpFdbAddress are being
forwarded.
invalid(2) : this entry is not longer valid
(e.g., it was learned but has since
aged-out), but has not yet been
flushed from the table.
learned(3) : the value of the corresponding
instance of usrBRTpFdbPort was
learned, and is being used.
self(4) : the value of the corresponding
instance of usrBRTpFdbAddress
represents one of the bridge's
addresses. The corresponding
instance of usrBRTpFdbPort
indicates which of the bridge's
ports has this address.
