LACP fallback
LACP fallback allows an active LACP interface to establish a port-channel before receiving LACP PDUs from the peer.
This feature is useful in environments where Preboot Execution Environment (PXE) servers are connected to switch with LACP port-
channel.
Whenever a PXE server reboots, both the port-channel and ports go down. While rebooting, the ports come up, but not the port-channel.
LACP fallback enables the port-channel to be up and keeps sending packets to the PXE server.
The LACP fallback feature adds a member port to LACP port-channel if it does not receive LACP PDUs from the peer for a particular
period of time. You can set the timer using the lacp fallback timeout timer-value command.
The member port becomes active and sends packets to the PXE server.
