8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information When you congure keepalive, the system sends a self-addressed packet out of the congured interface
to verify that the far end of a WAN link is up. When you congure no keepalive, the system does not
send keepalive packets and so the local end of a WAN link remains up even if the remote end is down.
