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.
Table 15-1 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
| |
|
|
Step 1 |
enable source-interface gigabitethernet slot/port
|
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 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
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:
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int tenGigabitEthernet 1/2/0
Router(config-if)#itu channel 20
Router# show hw-module subslot 1/2 transceiver 0 idpr dump
