CISCO-VRF-MIB

Monitored by Observium 
        The MIB module for provisioning and managing network
virtualization features. 
        
This module provides manageability for VRF, VRF-Lite and 
vNET. VRF stands for Virtual Routing and Forwarding. VRF 
is an extension of IP routing that provides multiple routing
instances. VRF provides independent routing instances and
hence the same or over-lapping addresses can be used without
conflicting each other. VRFs are used in conjunction with 
MPLS VPN to provide traffic separation between multiple VPN
customers. 
        
A VRF-Lite enabled device implements VRFs and does not require
MPLS for end to end communication. Instead of using MPLS
labels, VRF-Lite uses the interfaces to distinguish routes for
different VPNs. VRF-Lite forms virtual packet-forwarding tables
by associating one or more interfaces with each VRF, and
interfaces cannot belong to more than one VRF at any time.
        
VRF-Lite is an IP based hop-by-hop virtualization mechanism and
it involves complex configuration of every hop in the network.
vNET, virtual network, is also an IP based hop-by-hop mechanism
that can provide end-to-end virtualization of the network. vNET
greatly reduces the complexity in VRF-Lite deployment.
        
This MIB module will allow the user to perform the following
        
  * Create and monitor VRFs
  * Group VRFs to create VRF List
  * Associate/Dis-associate interface to/from a VRF
  * Enable vNET trunking on an interface
  * Specify VRF list per trunk

Notifications / Traps (4)
NameOIDDescription
cvVrfIfUp
IF-MIBifName cvVrfName cvVrfOperStatus
.1.3.6.1.4.1.9.9.711.0.1
This notification is generated when:
a. The ifOperStatus of an interface associated with a VRF
changes to the up(1) state.
b. When an interface with ifOperStatus = up(1) is
associated with a VRF.

The interface is identified by ifName and the VRF is
identified by cvVrfName varbinds respectively.
cvVrfIfDown
IF-MIBifName cvVrfName cvVrfOperStatus
.1.3.6.1.4.1.9.9.711.0.2
This notification is generated when:
a. The ifOperStatus of an interface associated with a VRF
changes to the down(2) state.
b. When an interface with ifOperStatus = up(1) state is
disassociated with a VRF.

The interface is identified by ifName and the VRF is
identified by cvVrfName varbinds respectively.

If all the interfaces associated with the VRF are in down(2)
state or if there are no more interfaces associated with the
VRF, then the cvVrfOperStatus will have a value of down(2).
cvVnetTrunkUp
IF-MIBifName
.1.3.6.1.4.1.9.9.711.0.3
This notification is generated when the ifOperStatus of a vNET
trunk interface changes to the up(1) state. The interface is
identified by ifName varbind. The notification will be
generated for only those interfaces for which the
cvInterfaceVnetTrunkEnabled object has a value of True(1).
cvVnetTrunkDown
IF-MIBifName
.1.3.6.1.4.1.9.9.711.0.4
This notification is generated when the ifOperStatus of a vNET
trunk interface changes to the down(2) state. The interface is
identified by ifName varbind. The notification will be
generated for only those interfaces for which the
cvInterfaceVnetTrunkEnabled object has a value of True(1).
