Step 1: Display the Status of a Channelized OC-12 IQ Interface
Action
To display the status of Channelized OC-12 IQ interfaces, use one or all of the following JUNOS CLI operational mode commands:
user@host> show interfaces terse coc*
user@host> show interfaces controller
user@host> show interfaces terse
Sample Output 1

What It Means
The sample output shows the status of both the physical and logical interfaces. In this example, all of the channelized OC-12 IQ interfaces are up.
Sample output 1 shows the channelized interfaces that are configured, but not the channels for those channelized interfaces.
Sample output 2 shows the channels for the channelized interfaces that are configured and the hierarchy, but not the interface address information. At the top, the hierarchy includes the controller interface coc12-0/0/0.
Sample output 3 shows all channelized interfaces and their configured channels and the address information.
When only one or some individual channels are down, you must troubleshoot the channel by checking the configuration, transmission network, and equipment. If all of the physical layers for the channels are down, you must work with this as a T1, T3, DS-0, or OC-12 SONET link or PIC problem. For more information on monitoring these types of interfaces, see the respective sections in this guide.
The interface configuration of the OC-12 IQ interface used for all show commands in this section is shown in Figure 22.
In addition, the configuration is shown in the following output:

The above configuration shows the OC-12 IQ interface configured into eight channels or slices as shown in Figure 22. A summary of the channels follows:
