CDP is used to obtain information about neighboring devices, such as the
types of devices connected, the interfaces they are connected to, the
interfaces used to make the connections, and the model numbers of the devices.
CDP is enabled on the Ethernet port of the access point by default. However,
CDP is enabled only on the radio port of the access point when the radio is
associated to another wireless infrastructure device, such as an AP or a
bridge. From the Services > CDP Page, CDP can be configured or
disabled
. Figure

the default CDP configuration on the AP. Figure

implement, monitor, and maintain CDP information. Examples of the show
cdp and show cdp entry command are shown in
