port-security MAC address restrictions and flexconnect

Hi - has anyone else seen this issue?

We use port-security on flexconnect ports limiting the maximum mac addresses to 100. The ports are configured so that the native vlan is the AP management vlan and we tag the wireless client vlan.

Recently we had an issue where we were seeing MAC address restriction violations on the ports connected to AP's. Although we could not see the violations happen in realtime they were in the switch logs. In Cisco Prime we checked the client counts on the AP's and they were less than 10 at that time the error occurred.

 

We then increased the max mac addresses to 200 and still saw the same issue. Removing port-security seemed to fix the problem.

This was the model and version of the switches.

WS-C2960X-24PS-L   15.0(2)EX4            C2960X-UNIVERSALK9-M

Has anyone else had this? 

 

Any help much appreciated.
