Displaying Extensive Status Information for a Specific ATM1 Interface
Purpose
To display extensive status information about a specific interface, use the following Junos OS CLI operational mode command:

Meaning
The sample output is for an OC3 ATM interface and shows the statistics for the SONET media, as well as the Input and Output ATM errors. Error details include input and output errors, active alarms and defects, and media-specific errors.
If the physical link is down, look at the active alarms and defects for the ATM interface and check the ATM media accordingly. SeeList of Common ATM Alarms and Error for an explanation of ATM alarms.
