CHAPTER 11
Configuring Dense Wavelength Division
Multiplexing Controllers
This module describes the configuration of dense wavelength division multiplexing (DWDM) controllers.
DWDM is an optical technology that is used to increase bandwidth over existing fiber-optic backbones.
DWDM can be configured on supported 10-Gigabit Ethernet (GE) or Packet-over-SONET/SDH physical
layer interface modules (PLIMs). After you configure the DWDM controller, you can configure an associated
10-Gigabit Ethernet interface.

Prerequisites for Configuring DWDM Controller Interfaces
You must be in a user group associated with a task group that includes the proper task IDs. The command
reference guides include the task IDs required for each command. If you suspect user group assignment is
preventing you from using a command, contact your AAA administrator for assistance.
Information About the DWDM Controllers
DWDM support in Cisco IOS XR software is based on the Optical Transport Network (OTN) protocol that
is specified in ITU-T G.709. This standard combines the benefits of SONET/SDH technology with the
multiwavelength networks of DWDM.
