Configuring SNMP Notification Receivers with VRFs

You can configure Cisco NX-OS to use a configured VRF to reach the host receiver. SNMP adds entries into
the cExtSnmpTargetVrfTable of the CISCO-SNMP-TARGET-EXT-MIB when you configure the VRF
reachability and filtering options for an SNMP notification receiver.
Note
You must configure the host before configuring the VRF reachability or filtering options.
