Enabling Support for Tunable DWDM-XFP-C

First Published: July 2013

The dense wavelength-division multiplexing (DWDM) wavelengths of the DWDM-XFP-C module on the Cisco ASR 1000 Series Aggregation Services Routers is tunable. You can configure the DWDM ITU wavelengths using the itu channel command in the interface configuration mode. The itu channel command ensures that the traffic continues to flow.

The following table contains the wavelength mapping information for the DWDM-XFP-C. module

Configuring the DWDM-XFP-C Module

Perform the following procedure to configure the DWDM-XFP-C module.

SUMMARY STEPS

    1.    enable source-interface gigabitethernet slot/port

    2.    configure terminal

    3.    interface tengigabitethernet slot/port

    4.    itu channel number


DETAILED STEPS
     Command or ActionPurpose
    Step 1enable source-interface gigabitethernet slot/port


    Example:
    Router# enable
     

    Enables the privileged EXEC mode. If prompted, enter your password.

     
    Step 2configure terminal


    Example:
    Router# configure terminal
     

    Enters the global configuration mode.

     
    Step 3interface tengigabitethernet slot/port


    Example:
    Router(config)# interface tengigabitethernet 4/11
     

    Specifies the 10-Gigabit Ethernet interface to be configured.

    Here:

    slot/port—Specifies the location of the interface.

     
    Step 4itu channel number


    Example:
    Router(config-if)# itu channel 28
     

    Sets the ITU channel.

    number—Specifies the ITU channel number. The acceptable values are from 1–82.

     

    Verifying the ITU Configuration

    The following example shows how to use the show hw-module subslot command to check an ITU configuration:

    Router# enable
Router# conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int tenGigabitEthernet 1/2/0
Router(config-if)#itu channel 20
Router(config-if)#
Router#
Router# show hw-module subslot 1/2 transceiver 0 idpr dump
