Understanding CDP

Cisco Discovery Protocol (CDP) is a device-discovery protocol that runs on all Cisco network
equipment. Each device sends identifying messages to a multicast address, and each device monitors the
messages sent by other devices. Information in CDP packets is used in network management software
such as CiscoWorks2000.
CDP is enabled on the WMIC's Ethernet and radio ports by default.
For best performance on your wireless LAN, disable CDP on all radio interfaces and on subinterfaces if
Note
VLANs are enabled.
