Step 3: Display Extensive Status Information for a Specific T3 Interface

Action

To display extensive status information about a specific channelized DS-3 to DS-0 interface or channelized DS-3 to DS-1 interface, use one of the following CLI operational mode commands:

user@host> show interfaces ds-fpc/pic/port:channel:channel extensive

user@host> show interfaces t1-fpc/pic/port:channel extensive

Sample Output

The following sample output is for a channelized DS-3 to DS-0 interface:

What It Means

The sample output shows where the errors might be occurring. Look at the active alarms and active defects for the DS-1 or DS-3 interface and diagnose the media accordingly. See Locate Multichannel DS-3 Alarms and Errors for an explanation of Multichannel DS-3 alarms.
