MIBs list

A bridge domain is one of the means by which it is possible to define a broadcast domain on a bridging device. It is an alternative to 802.1D bridge-groups and to 802.1Q VLAN bridging. Bridge domain is the service specification, and specifies the broadcast domain number on which this frame of this particular service instance must be made available on. The physical and virtual interfaces that can comprise a bridge domain are heterogeneous in nature comprising Ethernet service instances, WAN Virtual Circuit for ATM or Frame Relay and VFIs. However, the frame encapsulations for all interface types are essentially Ethernet. Without bridge-domains, VLANs would have to be globally unique per device and one would only be restricted to the theoretical maximum of 4095 VLANs for single tagged traffic. However with the introduction of bridge-domains, one can associate a service instance with a bridge-domain and all service instances in the same bridge-domain form a broadcast domain. Bridge-domain ID determines the broadcast domain and the VLAN id is merely used to match and map traffic. With bridge domain feature configured VLAN IDs would be unique per interface only and not globally.

This object indicates the number of bridge domain members configured on this bridge domain.
This table provides the bridge domain member attributes of the members currently configured for each bridge domain.
A conceptual row in cbdMemberInfoTable. This is indexed by ifIndex and cbdSIIndex. Each row is created when a bridge domain member is configured under a service instance.
This object indicates an arbitary index that uniquely identifies the Service Instance to which this bridge domain member belongs to.
This object identifies the type of the bridge domain member like ATM VC, Frame Relay VC, or Ethernet service.
This object indicates the operational state of the bridge domain Member. Operational state of the Bridge domain member is same as the operational state of the underlying service instance. Bridge domain members are configured under service instances and mu ...
This object indicates the administrative state of the bridge domain Member. Admin state of the Bridge domain member is same as the admin state of the underlying service instance. Bridge domain members are configured under service instances and multiple s ...
This object indicates whether split horizon is configured on this bridge domain member.
This object indicates the split horizon number if configured on the bridge domain member. Split horizon is used to avoid sending traffic between interfaces. Frames are not forwarded to the members belonging to the same split horizon group.
This object specifies the storage type of this conceptual row. This object can only have a value 'nonVolatile'. Other values are not applicable for this conceptual row and are not supported.
This object enables the SNMP agent to create, modify, and delete rows in the cbdMemberInfoTable.
This object indicates if cmac is configured on this bridge domain member. Cmac denotes if this bridge domain is configured as a customer domain.
This group contain information about bridge domain.
This group contain information related to bridge domain members.
