NPM Wireless Shows AP as down but it isn't?

Question

Hi all,

Anyone come across this before?

We have a virtual Cisco WLC running on a HyperV ** platform and until this past weekend all looked fine. However, it is showing one AP (our of approx 120) as down, but all of our checks show the AP is up and running just fine. Logging on to the WLC we can see it as up. We can ping it's listed IP, and a Show CDP Nei from its connected switch confirms it as up. As far as we can see, there has been no drop on this AP, but NPM thinks otherwise.

Any thoughts?

One other aspect that may (or may not) have an impact, is that we have the 'Remove Disappeared APs in Orion' set to off (unticked).

** I mention this specifically as the client recently migrated from an older ESX vWLC to this platform - and this is the only recent change.

SOLVED IT - or why you should never just listen to someone else.

Turns out, a section of the Cisco WLC I hadn't paid attention to in the past shows the 'admin status' of the AP. This one was set to disabled, so a simple change, repoll of the WLC and wait a minute caused it to show up as green.
