Avaya G430 - Interface Status Reports

Interface status reports
You report on the status of an interface using the show interfaces command. The
command reports on the administrative status of the interface, its operational status, and its
extended operational status (the ICMP keepalive status). For information about ICMP
keepalive status, refer to
ICMP keepalive on page 277.
For example, if an interface is enabled but normal keepalive packets are failing, show interfaces
displays:
FastEthernet 10/3 is up, line protocol is down
However, if normal keepalive reports that the connection is up but ICMP keepalive fails, the
following is displayed:
FastEthernet 10/3 is up, line protocol is down (no KeepAlive)
