    Example: OC12 Clear Channel on a Channelized OC12 IQ Interface

    Figure 1: OC12 Clear Channel on a Channelized OC12 IQ Interface

    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.

    Router A

    [edit]
    interfaces {coc12-4/2/0 {no-partition interface-type so;}so-4/2/0 {unit 0 {family inet {address 10.245.1.1/30;}}}}

    Verifying 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 option with the show interfaces command:
