describes possible command output for the show interface command.
Cause
The ATM line is up and operating correctly.
The ATM interface has been disabled with the
•
shutdown command.
or
The ATM line is down, possibly because the
•
ADSL cable is disconnected or because the
wrong type of cable is connected to the ATM
port.
The specified ATM subinterface is up and operating
correctly.
The specified ATM subinterface has been disabled
with the shutdown command.
The specified ATM subinterface is down, possibly
because the ATM line has been disconnected (by the
service provider).
The specified Fast Ethernet interface is connected to
the network and operating correctly.
The specified Fast Ethernet interface has been
correctly configured and enabled, but the Ethernet
cable might be disconnected from the LAN.
