CISCO-VLAN-IFTABLE-RELATIONSHIP-MIB

AI MIB Summary

The CISCO-VLAN-IFTABLE-RELATIONSHIP-MIB maps the correlation between VLAN identifiers (VLAN-id) and interface indices (ifIndex) for Cisco routed VLAN interfaces, including SVIs and encapsulated subinterfaces (ISL, 802.1Q, SDE). This mapping enables precise monitoring and management of Layer 3 routing instances associated with specific VLANs on Cisco routers and multilayer switches.

Cisco VLAN ifTable Relationship MIB lists VLAN-id and ifIndex information for routed VLAN interfaces. A routed VLAN interface is the router interface or sub-interface to which the router's IP address on the VLAN is attached. For example, an ISL, SDE, or 802.1Q encapsulated subinterface, or Switched Virtual Interface (SVI).

cviVlanInterfaceIndexTableThe cviVlanInterfaceIndexTable provides a way to translate a VLAN-id in to an ifIndex, so that the routed VLAN interface's routing configuration can be obtained from interface entry in ipRouteTable. Note that some routers can have interfaces to multiple VLAN management domains, and therefore can have multiple routed VLAN interfaces which connect to different VLANs having the same VLAN-id. Thus, it is possible to have multiple rows in this table for the same VLAN-id. The cviVlanInterfaceIndexTable also provides a way to find the VLAN-id from an ifTable VLAN's ifIndex.
SEQUENCE OF CviVlanInterfaceIndexEntry
.1.3.6.1.4.1.9.9.128.1.1.1
cviVlanInterfaceIndexEntryEach entry represents a routed VLAN interface, its corresponding physical port if any, and the ifTable entry for the routed VLAN interface. Entries are created by the agent when the routed VLAN interface is created. Operational status of routing does not affect the entries listed here. For routing configuration please refer to ipRouteTable. Entries are deleted by the agent when the routed VLAN interface is removed from the system configuration.
