C1832 & C2960s

[mgerguis]

we have in office multiple switches but the POE connecting to the Cisco Aironet 1832i is a Cisco Catalyst 2960s-48, all was working with little problems / disruption until recently a lot of problems began to show connecting to Wi-Fi for several users, though no network setting changes occurred that could be relevant

the C1832 controller currently showing:

as for the switch:

[Aug 17 05:12:08.367: %SW_MATM-4-MACFLAP_NOTIF: Host a402.b949.7866 in vlan 1 is flapping between port Po1 and port Gi1/0/25]

where the PO1 is trunk for the switch uplink & Port#25 is for the C1832 connection

any help would be appreciated to resolve whatever the problem or at least point to where I need to be looking

MAC Flaps are normal when a cleint roams from an AP connected on a different switch to this switch or vice versa.

looking at the logs I assume you are running mobility express, can you check whether all the AP's are registered to the controller. Make sure that you capture the complete log and upload it to https://cway.cisco.com/wireless-debug-analyzer/ , so u can get more visibility in to what each log message says.

Thanks for your advise, appreciate help on how to export the log to upload to that tool as trying to export using CLI "show logging" is not providing a file accepted by the tool & no output is created when uploading.

did you do "config paging disable" before "show logging" on CLI?
