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).
The 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.
cviVlanId
1.3.6.1.4.1.9.9.128.1.1.1.1.1
VlanIndexThe VLAN-id of a VLAN on ISL or 802.1q trunks.
Modification of default parameters is allowed. Implementations are allowed to restrict the range of VLANs.
For entities support up to 1024 VLANS. VLANs above 1000 are reserved for default VLANs and future use. Modification of default parameters is allowed. Creation or deletion of VLANs above 1000 is not allowed.
For a new object which needs the vlan-id of a VLAN as its SYNTAX, it is suggested to import VlanIndex from Q-BRIDGE-MIB instead of importing this TC here in CISCO-VTP-MIB. (0..4095) · Integer32
The VLAN-id number of the routed VLAN interface.
cviPhysicalIfIndex
1.3.6.1.4.1.9.9.128.1.1.1.1.2
InterfaceIndexOrZeroEither the value 0, or the ifIndex value of an interface in the ifTable. (0..2147483647) · Integer32
For subinterfaces, this object is the ifIndex of the physical interface for the subinterface.
For Switch Virtual Interfaces (SVIs), this object is zero.
cviRoutedVlanIfIndex
1.3.6.1.4.1.9.9.128.1.1.1.1.3
InterfaceIndexA unique value, greater than zero, for each interface or interface sub-layer in the managed system. It is recommended that values are assigned contiguously starting from 1. The value for each interface sub-layer must remain constant at least from one re-initialization of the entity's network management system to the next re-initialization. (1..2147483647) · Integer32 · hint d
The index for the ifTable entry associated with this routed VLAN interface.
