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
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.
