thanks for the input, appreciate the help.  Meraki's website suggested configuration with a 3850 is LACP.  Do AP's do PaGp? ... View more

Thanks for the suggestion, I am  planning on removing the port aggregation from the MR52, and remove LACP from the switch. ... View more

The AP go from my Cisco 3850 to my Nexus 9k, and the MAC address I see in the logs is the MAC address of the MR52 AP. ... View more

I have read other posts about MAC flapping, but there was nobody in the building, and no mac where roaming between AP's, and the MAC address is my AP. ... View more

Second attempt failed to upgrade MR52's, packet loss in AP's and slowness in switch after upgrade with MAC Flapping.  Everything works great on 25.13, but when I upgrade to 28.5, AP's show 100% loss when I ping them, and my Cisco 3850 switch runs super sluggish.  Tech Support helped me rollback to 25.13, but how to I get to a stable release?  The moment the AP's upgraded, and rebooted.  I see this in my Cisco 3850's, these mac flapping logs, and the MAC address is my MR52's.   Jan 10 18:26:08.134 MST: %SW_MATM-4-MACFLAP_NOTIF: Host e055.3dc0.2cb0 in vlan 72 is flapping between port Po24 and port Po1 Jan 10 18:26:08.571 MST: %SW_MATM-4-MACFLAP_NOTIF: Host e055.3dc0.30e2 in vlan 72 is flapping between port Po1 and port Po24 Jan 10 18:26:09.061 MST: %SW_MATM-4-MACFLAP_NOTIF: Host e055.3dc0.357a in vlan 72 is flapping between port Po1 and port Po24 Jan 10 18:26:11.991 MST: %SW_MATM-4-MACFLAP_NOTIF: Host e055.3dc0.22a0 in vlan 72 is flapping between port Po1 and port Po24 Jan 10 18:26:14.350 MST: %SW_MATM-4-MACFLAP_NOTIF: Host e055.3dc0.2cb0 in vlan 72 is flapping between port Po1 and port Po24 Jan 10 18:26:14.373 MST: %SW_MATM-4-MACFLAP_NOTIF: Host e055.3dc0.357a in vlan 72 is flapping between port Po1 and port Po22 Jan 10 18:26:14.375 MST: %SW_MATM-4-MACFLAP_NOTIF: Host e055.3dc0.30e2 in vlan 72 is flapping between port Po1 and port Po22 Jan 10 18:26:15.415 MST: %PLATFORM_MATM-4-QUEUE_OVERLIMIT: MATM dropped learn cache batch messages as queue limit has reached.
