Display the status of a Channelized OC12 or Channelized OC12 IQ interface to determine whether the physical link is up or down.
To verify that the status of the Channelized OC12 or Channelized OC12 IQ interface is up, use the following JUNOS command-line interface (CLI) operational mode command:

Meaning
The sample output shows that the physical link is up and there are no OC12 alarms or defects. You should not see any OC12 alarms. If there are SONET layer errors, see Investigate SONET Interfaces, for information on diagnosing SONET interface problems.
