Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes appropriate task
IDs. If the user group assignment is preventing you from using a command, contact your AAA administrator
for assistance.
You can set the wavelength to a specific ITU channel, that is represented by a channel number in the Multi
Source Agreement (MSA) ITU grid.
The spacing between wavelengths is 50 GHZ or 100 GHz. Use the
show controllers dwdm
command with
the
wavelength-map
keyword to view the channel numbers and wavelengths that are supported for a particular
controller.
The controller must be in the out-of-service state before you can use the
wavelength
command.

Examples
The following example shows how to set the DWDM wavelength to ITU channel 10.
RP/0/RP0/CPU0:router(config)#
controller dwdm 0/1/0/0
RP/0/RP0/CPU0:router(config-dwdm)#
wavelength 50GHz-grid 10
The following example shows how to set the frequency of ITU channel 10 to 195.8 THz.
RP/0/RP0/CPU0:router(config)#
controller dwdm 0/1/0/0
RP/0/RP0/CPU0:router(config-dwdm)#
wavelength 50GHz-grid frequency 19580
