Summary:A method and apparatus of a network element that configures a fault detection service is described. In an exemplary embodiment, the network element starts a fault detection service for the link on each of a first supervisor and a second supervisor of the network element. In addition, the first supervisor is active and the second supervisor is standby. The network element further saves a state for the fault detection service of the second supervisor. The network element additionally, and in response to a failover from the first supervisor to the second supervisor, continues the fault detection service of the second supervisor, wherein this fault detection service is active and sends fault detection packets on the link.
