CISCO-BRIDGE-EXT-MIB
AI MIB Summary
The CISCO-BRIDGE-EXT-MIB extends the standard BRIDGE-MIB to expose Cisco-specific bridge and switch port attributes, including proprietary VLAN configurations, port security violation counters, and spanning-tree protocol state extensions. This module enables granular monitoring of Layer 2 switching topology and security events on Cisco Catalyst and similar enterprise switching platforms.
A MIB module for extending BRIDGE-MIB specified in RFC 1493.

cbeDot1dTpGlobalAgingTimeThe timeout period in seconds for aging out
dynamically learned forwarding information at
the device level. Setting this object value to
zero will disable the aging out action globally
except at the VLANs where cbeDot1dTpVlanAgingTime
is configured.
802.1D-1990 recommends a default of 300 seconds.rw Unsigned32 (0 | 10..1000000 ) UNITS "seconds" .1.3.6.1.4.1.9.9.401.1.1.1 |
cbeDot1dTpVlanTableThis table provides the configuration for aging out
dynamically learned forwarding information at each VLAN.
This table is populated for each existing VLAN in the
device as well as non-existing VLANs which have the
aging out value configured. SEQUENCE OF CbeDot1dTpVlanEntry .1.3.6.1.4.1.9.9.401.1.1.2 |
cbeDot1dTpVlanEntryEach entry contains the aging out configuration
and the configuration source of the aging out value
applied at each VLAN. CbeDot1dTpVlanEntry .1.3.6.1.4.1.9.9.401.1.1.2.1 |
cbeDot1dTpVlanIndexIndicates the VLAN number. VlanIndex (Q-BRIDGE-MIB) .1.3.6.1.4.1.9.9.401.1.1.2.1.1 |
cbeDot1dTpVlanAgingTimeThe timeout period in seconds for aging out
dynamically learned forwarding information at
this VLAN. Setting this object value to zero
will disable the aging out action for this VLAN.
802.1D-1990 recommends a default of 300 seconds.
This object provides the same functionality as
dot1dTpAgingTime object in BRIDGE-MIB with one
exception that setting this object value to zero
will disable the aging out action for this VLAN.rw Unsigned32 (0 | 10..1000000 ) UNITS "seconds" .1.3.6.1.4.1.9.9.401.1.1.2.1.2 |
cbeDot1dTpVlanAgingFromGlobalIndicates whether the aging time applied at
this VLAN is from cbeDot1dTpGlobalAgingTime object
or not.
true(1) indicates the aging time applied at this VLAN is
from cbeDot1dTpGlobalAgingTime object. When true(1) is
configured, value of cbeDot1dTpVlanAgingTime object
in the same row will have the same value as
cbeDot1dTpGlobalAgingTime object.
false(2) indicates the aging time applied at this VLAN is
from cbeDot1dTpVlanAgingTime object.
If users configure cbeDot1dTpVlanAgingTime object in
the same row while this object value is true(1),
this object value will be changed to false(2) to reflect
that the aging time applied at this VLAN is not from
cbeDot1dTpGlobalAgingTime object.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.9.9.401.1.1.2.1.3 |
cbeDot1dTpVlanRowStatusThe status of this conceptual row entry. This object
is used to manage creation and deletion of rows in this
table.
To create an entry, users set the value of this object to
createAndGo(4). To delete an entry, users set the value
of this object to destroy(6).
Deletion of an entry in this table is only allowed
if the VLAN indicated by its row index object does not
exist in the device. cbeDot1dTpVlanAgingTime and
cbeDot1dTpVlanAgingFromGlobal can be modified at any time
(even while the row is active). If users set the value of
cbeDot1dTpVlanAgingFromGlobal object to true(1) and
the VLAN indicated by cbeDot1dTpVlanIndex object in the
same row does not exist, the entry will be removed from
this table.rw RowStatus (SNMPv2-TC) .1.3.6.1.4.1.9.9.401.1.1.2.1.4 |
cbeDot1dStatic OBJECT IDENTIFIER .1.3.6.1.4.1.9.9.401.1.2 |
cbeDot1dStaticTableA table containing filtering information configured into
the device by (local or network) management to specify
the set of bridge ports within a specific range of bridge
port number for a specific VLAN, to which frames received
from specific ports and containing specific destination
addresses are allowed to be forwarded. The value of zero
in this table as the port number from which frames with a
specific destination address are received, is used to
specify all ports for which there is no specific entry
in this table for that particular destination address.
Entries are valid for unicast and for group/broadcast
addresses. SEQUENCE OF CbeDot1dStaticEntry .1.3.6.1.4.1.9.9.401.1.2.1 |
cbeDot1dStaticEntryEach entry represents filtering information configured into
the device by (local or network) management specifying the
set of bridge ports within a specific range of bridge port
number for a specific VLAN, to which frames received from a
specific port and containing a specific destination address
are allowed to be forwarded. CbeDot1dStaticEntry .1.3.6.1.4.1.9.9.401.1.2.1.1 |
cbeDot1dVlanIndexThe VLAN ID of a specific VLAN. VlanIndex (Q-BRIDGE-MIB) .1.3.6.1.4.1.9.9.401.1.2.1.1.1 |
cbeDot1dStaticAddressThe destination MAC address in a frame to which
this entry's filtering information applies. This
object can take the value of a unicast address, a
group address or the broadcast address. MacAddress (SNMPv2-TC) .1.3.6.1.4.1.9.9.401.1.2.1.1.2 |
cbeDot1dStaticReceivePortEither the value '0', or the port number of the
port from which a frame must be received in order
for this entry's filtering information to apply.
A value of zero indicates that this entry applies
on all ports of the bridge for which there is no
other applicable entry. Integer32 (0..65535 ) .1.3.6.1.4.1.9.9.401.1.2.1.1.3 |
cbeDot1dStaticPortRangeIndexThe index that uniquely identifies a particular
range of bridge port number. CiscoPortListRange (CISCO-TC) .1.3.6.1.4.1.9.9.401.1.2.1.1.4 |
cbeDot1dStaticAllowedToGoToA set of ports in a specific VLAN, in a specific range of
bridge port number, to which frames received from a specific
port, destined for a specific MAC address are allowed to be
forwarded.
An entry in this table with the index value of
cbeDot1dStaticPortRangeIndex being 'oneto2K' and instance
value of the corresponding cbeDot1dStaticAllowedToGoTo being
zero-length octet string indicates that frames received in
the VLAN as specified by this entry's cbeDot1dVlanIndex, from
a port as specified by this entry's cbeDot1dStaticReceivePort,
and destined to the MAC address as specified by this entry's
cbeDot1dStaticAddress, are not allowed to be forwarded to any
of the ports in this VLAN.rw CiscoPortList (CISCO-TC) .1.3.6.1.4.1.9.9.401.1.2.1.1.5 |

other(1) - this entry is currently in use but
the conditions under which it will remain
so differ from the following values.
invalid(2) - writing this value to the object
removes the corresponding entry.

and will remain so after the next reset of
the bridge.
