CDP on radio interface

[rsumpter]

Is there any benefit to turning on CDP for the radio interface?

Well I do not think you get any major benefits other then identifying the parameters set on the wireless device to which the radio interface is connected to. In case if you are running any VLANs on the AP it's better you disable CDP on the radio interface.

For  best performance on your wireless LAN, disable CDP on all radio  interfaces and on sub-interfaces if VLANs are enabled on the access  point.
