Step 4: Display Extensive Status Information for a Channelized OC-12 IQ Interface

Action

To display extensive status information for a Channelized OC-12 IQ interface, use the following JUNOS CLI operational mode command:

user@host> show interfaces interface-type-interface-name extensive

What It Means

The sample output shows where the errors might be occurring: either with the channel media or the SONET layer. In this example, there are no errors. However, if errors occur, you must troubleshoot the channel media or the SONET layer. For more information, see the sections of this guide that correspond to the media with which you are working.
