Interfaces MIB—SNMP context–based access

The Interfaces MIB—Simple Network Management Protocol (SNMP) context–based access feature provides ability to query the Interfaces MIB objects and the information returned will be restricted to the VRF to which the SNMP context is mapped to. Notification hosts may also be configured with contexts to restrict the notifications that need to be sent to the particular host.

Information about Interfaces MIB—SNMP context–based access

The interface MIB (IF-MIB) has been modified to support context-aware packet information in virtual route forwarding (VRF) environments. VRF environments require that contexts apply to VPNs so that clients can be given selective access to the information stored in the IF-MIB. Clients that belong to a particular VRF can access information about the interface from the IF-MIB that belongs to that VRF only. When a client tries to get information from an interface that is associated with a particular context, the client can see only the information that belongs to that context and cannot see information to which it is not entitled.

No commands have been modified or added to support this feature. This feature is automatically enabled when VRF is configured.

The IF-MIB supports all tables defined in RFC 2863 and the CISCO-IFEXTENSION-MIB.
