CTRON-Q-BRIDGE-MIB-EXT
AI MIB Summary
The CTRON-Q-BRIDGE-MIB-EXT module enables SNMP management of Cabletron enterprise switches to configure and monitor IEEE 802.1Q VLAN tagging parameters and Q-BRIDGE-MIB attributes. It provides specific access to switch bridging tables, VLAN membership, and port-based VLAN configuration states for legacy Cabletron hardware.
This MIB module defines a portion of the SNMP enterprise MIBs under the Cabletron enterprise OID pertaining to the configuration of switches that support IEEE 802.1Q [802.1Q] and the Q-BRIDGE-MIB [RFC2674].

ctQBridgeMibExtThis MIB module defines a portion of the SNMP enterprise
MIBs under the Cabletron enterprise OID pertaining to
the configuration of switches that support IEEE 802.1Q
[802.1Q] and the Q-BRIDGE-MIB [RFC2674]. MODULE-IDENTITY .1.3.6.1.4.1.52.4.1.2.16.7 |

ctDot1qPortVlanExtTableA table containing per port control and status information
for Cabletron proprietary extensions pertaining to VLAN
configuration in the device. SEQUENCE OF CtDot1qPortVlanEntry .1.3.6.1.4.1.52.4.1.2.16.7.1.1 |
ctDot1qPortVlanEntryInformation controlling proprietary VLAN configuration for
a port on the device. This is indexed by dot1dBasePort. CtDot1qPortVlanEntry .1.3.6.1.4.1.52.4.1.2.16.7.1.1.1 |
ctDot1qPortDefaultForwardModeThe method used to forward frames belonging to VLANs that
do not have an entry in the dot1qVlanCurrentTable.
When this is forwardNoFrames(1), the device will not forward
traffic out this port, for any VLAN that does not have an
entry in the dot1qVlanCurrentTable.
When this is forwardAllFramesAsTagged(2), the device will
forward all traffic out this port, with an 802.1Q VLAN tag,
for any VLAN that does not have an entry in
dot1qVlanCurrentTable.
When this is forwardAllFramesAsUntagged(3), the device will
forward all traffic out this port, without an 802.1Q VLAN tag,
for any VLAN that does not have an entry in
dot1qVlanCurrentTable.
This control does not affect VLAN independent BPDU frames,
such as GVRP and STP. It does affect VLAN dependent BPDU
frames, such as GMRP.rw Enumeration .1.3.6.1.4.1.52.4.1.2.16.7.1.1.1.1 |
ctDot1qPortDiscardTaggedThe method used to discard all incoming VLAN tagged frames
for the port specified by the indexing of this entry.
When this is enabled(1), the device will discard all 802.1Q
tagged packets received on this port.
When this is disabled(2), the device will NOT discard frames
received on this port based on the presence of an 802.1Q tag.
The behavior of this method in conjunction with the
dot1qPortAcceptableFrameTypes leaf of Q-BRIDGE-MIB [RFC2674]
is that of a logical OR.rw EnabledStatus (P-BRIDGE-MIB) .1.3.6.1.4.1.52.4.1.2.16.7.1.1.1.2 |
ctDot1qPortReplaceTCIThe method used to replace the Tag Control Information (TCI)
field in all VLAN tagged frames received on the port specified
by the indexing of this entry.
When this is enabled(1), the device will replace the 802.1Q
TCI field with results of the INGRESS stage of frame forwarding.
Logically, this happens immediately prior to the PROGRESS stage
of frame relay.
When this is disabled(2), the device operates in compliance with
the IEEE 802.1Q standard and honors the TCI field of incident
frames.rw EnabledStatus (P-BRIDGE-MIB) .1.3.6.1.4.1.52.4.1.2.16.7.1.1.1.3 |
ctDot1qVlanDynamicEgressTableA table containing per VLAN control and status
information for Cabletron proprietary egress extensions for
VLAN configuration in the device. SEQUENCE OF CtDot1qVlanDynamicEgressEntry .1.3.6.1.4.1.52.4.1.2.16.7.1.2 |
ctDot1qVlanDynamicEgressEntryInformation controlling proprietary VLAN configuration
for a device. CtDot1qVlanDynamicEgressEntry .1.3.6.1.4.1.52.4.1.2.16.7.1.2.1 |
ctDot1qVlanDynamicEgressIndexThe VLAN to which this entries' dynamic egress status
applies. VlanIndex (Q-BRIDGE-MIB) .1.3.6.1.4.1.52.4.1.2.16.7.1.2.1.1 |
ctDot1qVlanDynamicEgressStatusThe state of Dynamic Egress operation on this VLAN. The
value enabled(1) indicates that Dynamic Egress is enabled on
this VLAN. If Dynamic Egress is enabled for a VLAN the
following rules are applied to received frames:
1. If the frame is untagged, and
2. The frame is successfully classified to the specified
VLAN, and
3. The port the frame was received on is not configured in
dot1qVlanCurrentEgressPorts, dot1qVlanCurrentUntaggedPorts,
or dot1qVlanForbiddenEgressPorts, for the classified VLAN,
and
4. The port is configured for forwardNoFrames(1) in
ctDot1qPortDefaultForwardMode (if supported), then
5. The port the frame was received on will be added to
the dot1qVlanCurrentEgressPorts and
dot1qVlanCurrentUntaggedPorts for the classified VLAN.
If the VLAN was not preexisting the dot1qVlanStatus
leaf for the VLAN will return other(1).rw EnabledStatus (P-BRIDGE-MIB) .1.3.6.1.4.1.52.4.1.2.16.7.1.2.1.2 |
ctDot1qVlanCurrentExtTableA table containing current configuration information
