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.

Table 4 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 source-interface gigabitethernet slot/port Example: Router# enable	Enables the privileged EXEC mode. If prompted, enter your password.
Step 2	configure terminal Example: Router# configure terminal	Enters the global configuration mode.
Step 3	interface tengigabitethernet slot/port 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 4	itu 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
