Is it only 11a radios? Are you getting DFS events? If so, I'm dealing
with this right now with TAC. Check your AP log for a DFS message.

Anyone with Cisco APs and Cisco Prime get these odd alerts from PI
that state the radio is administratively up but operationally down
with a reason of unknown? I have been getting a slew of these
lately. We have introduced quite a few 1702’s into our environment
and I am wondering if there is some issue with recalculation, or
something that triggers a radio reset to resolve a different issue?
Below is the alert notification. Cisco forums haven’t been much help,
so I figured I’d take a shot at the group. Thanks!
