Figure 1: OC12 Clear Channel on a Channelized OC12 IQ Interface
The key to this simple example is to remove all partitions from the channelized interface. To configure a clear channel on a channelized IQ interface, include the no-partition statement at the [edit interfaces coc12-fpc/pic/0] hierarchy level and select the interface type. After you commit this part of the configuration, the clear channel is set and you can configure the resulting SONET interface normally.

- coc12-4/2/0 {

To verify correct operation of a channelized OC12 IQ interface configured as a clear channel, use the following commands:
To view the interface names of the physical channelized OC12 IQ interface and the clear channel OC12 interface configured on the channelized IQ interface, use the show interfaces controller command:
user@RouterA> show interfaces controller
Controller Admin Link coc12-4/2/0 up up # This is the physical channelized OC12 IQ interface. so-4/2/0 up up # This is the resulting SONET OC12 interface.
To view information about the physical channelized interface, include the cxx-fpc/pic/0 option with the show interfaces command:
user@RouterA> show interfaces
