Enabling Support for Tunable DWDM-XFP-C

The dense wavelength-division multiplexing (DWDM) wavelengths of the DWDM-XFP-C module on the Cisco ASR 900 Series router 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.

Table 9-1 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

2. configure terminal

3. interface tengigabitethernet slot/port

4. itu channel number

DETAILED STEPS

Command or Action
Purpose

Step 1

enable

 
Router# enable

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

Step 2

configure terminal

 

Router# configure terminal

Enters the global configuration mode.

Step 3

interface tengigabitethernet slot/port

 

Router(config)# interface tengigabitethernet 0/3

Specifies the 10-Gigabit Ethernet interface to be configured.

  • slot/port—Specifies the location of the interface.

Step 4

itu channel number

 

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# show hw-module subslot 0/2 transceiver 0 idprom dump
