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

Action

To display the status of Channelized DS-3 interfaces, use the following JUNOS CLI operational mode command:

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

Sample Output 1

What It Means

The sample output shows very detailed interface information which includes where any errors might be occurring. The first line of the output indicates if the link is up. Sample output 1 and 2 show that both links are up. Sample output 3 shows that the link is down. The main sections of the output to examine are:

• DS-1 alarms
• DS-1 defects
• T1 media

Both sample output 1 and 2 show no DS-1 alarms or defects. Sample output 3 shows AIS and LOF alarms and defects. For more information about AIS and LOF alarms and defects, see Locate SONET Alarms and Errors.

Even though there are counts in the T1 media section of the output in sample output 1 and 2, the State column indicates that the media are OK. However, sample output 3, in which the link is down, shows that the AIS and LOF defects are active.
