Suddenly, Cisco 3500 APs on two controllers running 7.6.110 are letting go of the controllers frequently, and intermittently. The APs are managed on dedicated private space, on the same VLAN as the controllers. The APs ARE NOT LOSING IP ADDRESSES OR SWITCH CONNECTIVITY AND NO SWITCHES INVOLVED ARE PROBLEMATIC. It feels suddenly like the VLAN is going haywire (one VLAN among dozens on same switches that are fine), with no explanation found yet, or code funkiness.
My question is coming from the code side- has anyone been through this sort of condition on Cisco AP/controllers on or near this 7.6.110 code version? APs get good DHCP, find controller, settle in, start serving clients. Randomly and frequently, AP will either jump to another controller or fall off totally and eventually reboot. Condition repeats. Just looking for ideas from code side, if it's ringing any bells.
