MSM7xx Controllers Configuration Guide v6.4.0

On all other controllers
CDP configuration
The controller can be configured to transmit CDP (Cisco Discovery Protocol) information on the
LAN and Internet ports. This information is used to advertise controller information to third-party
devices, such as CDP-aware switches. Network managers can retrieve this information allowing
them to determine the switch ports to which different controllers are connected.
The controller always listens for CDP information on the LAN and Internet ports, even when this
option is disabled, to build a list of autonomous APs. CDP information from third-party devices and
controlled APs is ignored.
NOTE: Controlled APs always send CDP information.
