Thanks Lee - The APs are using DHCP, and the DHCP seems to be fine (both servers up/passing IPs). Only 1 HA cluster (700+ APs) has had this problem, the other HA cluster has not (over 600 APs). The APs are not losing IP, nor rebooting - just dropping CAPWAP.

Do the APs use DHCP or static addresses? If DHCP, have you verified all is well in that regard between APs and server? -Lee Badman From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Danny Eaton Sent: Friday, February 07, 2014 11:19 AM To: [email protected] Subject: [WIRELESS-LAN] Cisco 7.6.100.0 question...... So, I've been running 2 WiSM-2 HA clusters running 7.6.100.0 in non-VSS for about a month. In the last week one of the clusters has had every AP (1142's and 3502's) drop the CAPWAP tunnel to the controller. The controller has not failed over, the 6500 chassis either reside in have not failed, OSPF or BGP flapped, the APs haven't even rebooted - just dropped the CAPWAP tunnel. The only thing I've seen in logs is this: AP 'ap-NAME_HERE, MAC: 00:25:45:XX:XX:XX disassociated previously due to AP Reset. Uptime: 0 days, 00 h 01 m 11 s . Reason: watchdog timer reset. I do have a TAC case open, but wanted to reach out and see if anyone else has seen similar behavior. Respectfully, Danny Eaton Snr.
