Step 1: Display the Status of Channelized Interfaces

Action

To display the status of channelized DS-3 to DS-0 interfaces or channelized DS-3 to DS-1 interfaces, use one of the following JUNOS command-line interface (CLI) operational mode commands:

user@host> show interfaces terse ds*

user@host> show interfaces terse t1*

Sample Output

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

user@host> show interfaces terse ds* 

Interface       Admin Link Proto Local                 Remote

ds-2/1/0:5:1    up    up  

ds-2/1/0:5:1.0  up    up   inet 192.168.140.197/30

The following sample output is for a channelized DS-3 to DS-1 interface:

user@host> show interfaces terse t1*

[...Output truncated...]

t1-2/1/0:16    up    down

t1-2/1/0:16.0   up    down inet 192.168.118.61/30

t1-2/1/0:17     up    up  

t1-2/1/0:17.0   up    up   inet 192.168.118.49/30

t1-2/1/0:18     up    up  

t1-2/1/0:18.0   up    up   inet 192.168.36.21/30 

t1-2/1/0:19     up    up  

t1-2/1/0:19.0   up    up   inet 192.168.118.97/30

What It Means

The sample output shows the status of both the physical and logical interfaces. In both sample outputs, all links are up except for the first interface in the T1 sample output. The first interface, t1-2/1/0:16, has both the physical and logical links down.
