CDP Disabled Cisco 1142 / 3502 Lightweight APs

These little gotchas are coming in thick and fast, this time CDP is disabled by default after the APs join the WLC or they don’t show up after a power outage.

What does it affect?

Seems to be affecting 3502 / 1142 APs so far

What happens?

The APs don’t show up in cdp neighbours when issuing a show cdp neighbours on the switch they are attached to.

Whats the fix?

Log into the CLI and issue the following commands:

(Cisco Controller) > config ap cdp enable all
(Cisco Controller) > config ap cdp interface ethernet 0 enable all
(Cisco Controller) > save config

Do a show cdp neighbours on your attached switch to confirm the APs are now showing up.
