IEEE8021-BRIDGE-MIB
AI MIB Summary
The IEEE8021-BRIDGE-MIB provides standardized SNMP access to monitor and manage Layer 2 bridging parameters, including MAC address tables, bridge port states, spanning tree topology, and VLAN configurations on IEEE 802.1D and 802.1Q compliant network devices. It enables the collection of critical operational metrics such as port counters, bridge ID, and forwarding database entries to facilitate troubleshooting and topology verification in Ethernet switching environments.
The Bridge MIB module for managing devices that support IEEE 802.1D. This MIB module is derived from the IETF BRIDGE-MIB, RFC 4188.
Unless otherwise indicated, the references in this MIB module are to IEEE Std 802.1Q-2011.

ieee8021BridgeBase OBJECT IDENTIFIER .1.3.111.2.802.1.1.2.1.1 |
ieee8021BridgeBaseTableA table that contains generic information about every
bridge component. All writable objects in this table
MUST be persistent over power up restart/reboot. SEQUENCE OF Ieee8021BridgeBaseEntry .1.3.111.2.802.1.1.2.1.1.1 |
ieee8021BridgeBaseEntryA list of objects containing information for each bridge
component. Ieee8021BridgeBaseEntry .1.3.111.2.802.1.1.2.1.1.1.1 |
ieee8021BridgeBaseComponentIdThe component identifier is used to distinguish between the
multiple virtual bridge instances within a PBB. In simple
situations where there is only a single component the default
value is 1. IEEE8021PbbComponentIdentifier (IEEE8021-TC-MIB) .1.3.111.2.802.1.1.2.1.1.1.1.1 |
ieee8021BridgeBaseBridgeAddressThe MAC address used by this bridge when it is
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
ieee8021SpanningTreePriority, a unique BridgeIdentifier
is formed, which is used in the Spanning Tree Protocol.
This object may not be modified while the corresponding
instance of ieee8021BridgeBaseRowStatus is active(1).
The value of this object MUST be retained across
reinitializations of the management system.rw MacAddress (SNMPv2-TC) .1.3.111.2.802.1.1.2.1.1.1.1.2 |

entity.ro Integer32 UNITS "ports" .1.3.111.2.802.1.1.2.1.1.1.1.3 |
ieee8021BridgeBaseComponentTypeIndicates the component type(s) of this bridge. The
following component types are possible:
iComponent(1) - An S-VLAN component of a Backbone
Edge Bridge which performs encapsulation of customer
frames.
bComponent(2) - An S-VLAN component of a Backbone
Edge Bridge which bundles backbone service instances
into B-VLANs.
cVlanComponent(3) - A C-VLAN component of an
enterprise VLAN bridge or of a Provider Bridge used
to process C-tagged frames.
sVlanComponent(4) - An S-VLAN component of a
Provider Bridge.
dBridgeComponent(5) - A VLAN unaware component of an
802.1D bridge.
erComponent (6) - An Edge Relay component of an EVB Station.
tComponent (7) - A TPMR component in a Backbone Edge Bridge.
This object may not be modified while the corresponding
instance of ieee8021BridgeBaseRowStatus is active(1).

ieee8021BridgeBaseDeviceCapabilitiesIndicates the optional parts of IEEE 802.1D and 802.1Q
that are implemented by this device and are manageable
through this MIB. Capabilities that are allowed on a
per-port basis are indicated in
ieee8021BridgeBasePortCapabilities.

ieee8021BridgeBaseTrafficClassesEnabledThe value true(1) indicates that Traffic Classes are
enabled on this bridge. When false(2), the bridge
operates with a single priority level for all traffic.
This object may be modified while the corresponding
instance of ieee8021BridgeBaseRowStatus is active(1).
The value of this object MUST be retained across
reinitializations of the management system.rw TruthValue (SNMPv2-TC) .1.3.111.2.802.1.1.2.1.1.1.1.6 |
ieee8021BridgeBaseMmrpEnabledStatusThe administrative status requested by management for
MMRP. The value true(1) indicates that MMRP should
be enabled on this device, in all VLANs, on all ports
for which it has not been specifically disabled. When
false(2), MMRP is disabled, in all VLANs and on all
ports, and all MMRP packets will be forwarded
transparently. This object affects both Applicant and
Registrar state machines. A transition from false(2)
to true(1) will cause a reset of all MMRP state
machines on all ports.
This object may be modified while the corresponding
instance of ieee8021BridgeBaseRowStatus is active(1).
The value of this object MUST be retained across
reinitializations of the management system.rw TruthValue (SNMPv2-TC) .1.3.111.2.802.1.1.2.1.1.1.1.7 |
ieee8021BridgeBaseRowStatusThe object indicates the status of an entry, and is used
to create/delete entries.
The following objects MUST be set prior to making a new
entry active:
ieee8021BridgeBaseBridgeAddress
ieee8021BridgeBaseComponentType
ieee8021BridgeBaseDeviceCapabilities
It is recommended that these three objects not be allowed
to be modified while the corresponding instance of
ieee8021BridgeBaseRowStatus object is active(1).

making a new entry active (they will take their defaults),
and they also may be modified while the corresponding
instance of this object is active(1):

of other objects in this table MUST be retained across

defined in the IF-MIB, for the interface corresponding
to this port, or the value 0 if the port has not been
bound to an underlying frame source and sink.
