CHAPTER 21
Implementing CDP
Cisco Discovery Protocol (CDP) is a media- and protocol-independent protocol that runs on all
Cisco-manufactured equipment including routers, bridges, access and communication servers, and switches.
Using CDP, you can view information about all the Cisco devices that are directly attached to the device.
This module describes the new and revised tasks you need to implement CDP on your Cisco IOS XR network.
For more information about CDP on the Cisco IOS XR software and complete descriptions of the CDP
commands listed in this module, refer to Related Documents, on page 402. To locate documentation for other
commands that might appear in the course of running a configuration task, search online in Cisco ASR 9000
Series Aggregation Services Router Commands Master List.
