Checking Your Work

To verify correct operation of a channelized OC12 IQ interface configured as a clear channel, use the following commands:

• show interfaces
• show interfaces controller

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 (interface name) option with the show interfaces command:
