Step 3: Display Extensive Status Information for a Specific Channelized OC-12 Interface

Action

To display extensive status information for a Channelized OC-12 interface, use the following JUNOS CLI operational mode command:

user@host> show interfaces t3-fpc/pic/port:channel extensive

What It Means

The sample output shows where the errors might be occurring, either with the T3 media or the SONET layer. In this example, there are no SONET or DS-3 alarms or defects. However, if errors occur, you must troubleshoot the T3 media or the SONET layer. For more information on diagnosing a T3 media problem, see Investigate T3 Interfaces. For more information about diagnosing a SONET layer problem, see Investigate SONET Interfaces.
