Step 4: Monitor Statistics for a Channelized DS-3 Interface
Action
To display the status of Channelized DS-3 interfaces, use the following JUNOS CLI operational mode command:
user@host>monitor interfaces t1-fpc/pic/port:channel

Interface warnings:
o Outstanding DS1 alarm(s)
o INET NCP is not Opened
o LCP state is not Opened
Next='n', Quit='q' or ESC, Freeze='f', Thaw='t', Clear='c', Interface='i'
What It Means
The sample output shows common interface failures, indicates whether loopback is detected, and shows increases in framing errors. Use information from this command to help narrow down possible causes of an interface problem.
The output in the examples is static, however, the counters in real time change as they are updated every second. The counters in sample output 3 show that there is no traffic for the interface that is down, and that it has active alarms, defects, and there are interface warnings.
