Checking Your Work

To verify correct operation of a channelized OC12 IQ interface configured for complex channelization, use the following commands:

• show interfaces controller
• show interfaces
• show interfaces interval (for OC12, channelized OC12, OC3, T3, channelized T3, T1, and channelized T1 channels)

To view the names of the resulting interfaces and channelized interfaces configured on a channelized OC12 IQ interface, use the show interfaces controller command:

user@RouterA> show interfaces controller

To verify that your channelized IQ interfaces are working as expected, use the show interfaces command. Use the show interfaces controller command to find the name of the channelized interface you want to view; then include this channelized name (for example, ct3-4/2/0:4) as an option with the show interfaces command.

The next section provides sample show interfaces output for each of the major interface types configured in this example:

• Channelized OC12
• SONET OC3
• T3
• Channelized T3
• Channelized OC1
• Channelized T1
• T1
• DS0
