Step 1: Display the Status of Channelized DS-3 Interfaces

Action

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

user@host> show interfaces t1* terse 

Sample Output 1

What It Means

The sample output shows the status of both the physical and logical interfaces. Sample output 1 shows that 12 of the possible 28 channels have IP addresses and are connected. Of the 12 connected channels, the last channel (t1-1/2/0:19.0) is currently down.

Sample output 2 shows that all links are up except for interface t1-0/3/3:0, which has both the physical and logical links down.
