Output

Cause

For ATM Interfaces

ATM 0 is up, line protocol is up

The ATM line is up and operating correctly.

 

 

ATM 0 is down, line protocol is down

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.
