Usage
Information
When you configure keepalive, the system sends a self-addressed packet out of the configured
interface to verify that the far end of a WAN link is up. When you configure 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.

of 4; for example, 0, 4, 8, 12, ... 120, 124, 128).
