I recently had a number of CAPWAP access points lose IP connectivity, but were still up at L2 and seen by CDP. Resetting them via PoE port shutdown recovered them, but no AP crash log or useful log info on the WLC. The AP also had no local logging info after the reset.
Does anyone know a way to get the AP to log locally to NVRAM? Or why this isn't enabled/possible?
I assume that syslog to a server will be of little benefit...
Thanks in advance.
Interesting issue. What model aps and what wlc code are you on ? I recently had an issue where aps would reset themselves back to factory default .. I sent those aps in for inspection. It was only a few ..

They are 3600 on v22.214.171.124
The IP was still showing in CDP but not responding on any port.
They got different IP addresses from the core switch DHCP pool when they came back up. I think this is just because they were offline for long enough to lose the binding.
Can only assume that something went wrong in the IP stack on the AP NIC

If console access is possible you may console to an AP during the issue and check any local logging. Check also if it still has an IP address or not during the issue. There will probaby be some info about why the AP L3 connectivity got broken.
Just a though.
