We have 5 Aironet 1100 series APs deployed in one of our buildings. A few days ago, 3 of them showed down in our monitoring. The next day the other 2 showed down. When I go to the switches that they are attached to and do a show cdp neighbor detail, I see all the access points but NO IP address. Also, when I went to to site, I can connect to the APs via wireless and be on the network just fine. We have static IP addresses assigned to them. However, they are not pingable and do not show up in the ARP table of the switch.
They have been running a couple of years without changes.
