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 STEPS1.
enable source-interface gigabitethernet slot/port
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
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 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
