Setting this object to true causes the five-minute hold-down timer for emitting URPF drop rate notifications for IP version fsUrpfIfIpVersion on the interface to be short-circuited. If a notification is due and would be emitted for the interface if the five-minutes elapsed, setting this object will cause the notification to be sent. This is a trigger, and doesn't hold information. It is set and an action is performed. Therefore a get for this object always returns false. Relation CLI: clear ip urpf interface.
