A few times a week, I get an alert saying that an AP or list of APs have disassociated from the Controller. This is the message I get:
Virtual Domain: ROOT-DOMAIN
"PI has detected one or more alarms of category AP and severity Critical in Virtual Domain ROOT-DOMAIN for the following items:
1. Message: 802.11b/g/n interface of AP RC302 is down: Controller ..."
I am using the following AP:
AP Type: CAPWAP
AP Model: AIR-LAP1142N-A-K9
IOS Version: 15.2(4)JB6$
The Controller is a Cisco 5500 series running 7.6.130
After about 7 minutes or so they reassociate. What could be causing this?
