Thanks for your reply.
For now we are not ruling out the MAC FLAPS as the possible cause of the AP reboot and sluggish network access as so far its only the logs we see on the switches.
Can you suggest other things we need to look at to isolate the issue that we are experiencing?
Just to add that with regards to spanning-tree, the Core Switch is defined as the Root Bridge with Spanning Tree BPDU Guard Default enabled on all switches. All Access Switches are connected to the Core Switch with single line fiber (no redundancy link) except for the one location which we have 2 links we bundled as Etherchannel.
The ZoneDirector was enabled as meshed as we are using mesh AP some locations without available cabling.
In another setup we have which is similar with the one I described above, we are seeing that whenever a syslog was generated for MAC FLAP on the switch, we noticed that on the POS (Point of Sale) Unit the response becomes sluggish, almost unusable at the time it occurs.
Thanks and Best Regards,
