If fast path i...Fast path is an alternative routing mechanism to the routing table, in which the responses to incoming network traffic are sent back by using the same interface as the incoming traffic. If fast path is enabled on an interface group and a physical interface in that group receives an incoming request, fast path does not govern which physical interface group member port sends a response to the request (this is specifically related to LACP or static multimode interface group).
