This read-write TruthValue object controls whether the device generates SNMP notifications when a VRF interface's status changes. An administrator enables this so that a management station is alerted automatically whenever an interface associated with a VRF goes up or down, rather than having to poll for the change. For example, with this object set to true, the loss of the last up interface in a customer VRF would trigger a notification instead of going unnoticed until the next poll.
