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.
monitor interface
Monitor counters on a single interface or all interfaces on a stack-unit. The screen is refreshed every five
seconds and the CLI prompt disappears.
