System and method of handling a fault detection mechanism with link aggregation groups

Abstract:

A method and apparatus of a network element that configures a fault detection service on a multi-link group of a network element is described. In this embodiment, the network element starts the fault detection service on a first link of the multi-link group. The network element further configures a first packet for the fault detection service and transmits the first packet on the first link. The network element additionally receives the first packet and determines if the first packet was received on the first link. If the first packet was received on a different link, the network element configures a second packet by modifying a packet characteristic of the first packet and transmits the second packet on the first link. If the first packet was received on the first link, the network element marks the fault detection service for the first link as converged.
