Wireless Client MAC flaps

Hi All,

I sometimes see the following log on the core C3750X.

%SW_MATM-4-MACFLAP_NOTIF: Host xxxx.xxxx.xxxx in vlan 100 is flapping between port Po1 and port Po2

Po1 is conneted to WLC through C2960S, and Po2 is connected to AP through another C2960S.

I cannot get why flapping happens between the port to WLC and that to AP.

EtherChannel is correctly configured as long as I see.

Any ideas on this problem?

Thank you in advance.

Re: Wireless Client MAC flaps

Don't quite understand. Your WLC is setup with LAG and you have an etherchannel going to only one switch. The AP's are on static ports and there is an etherchannel between the two switches? The access points are in local of FlexConnect mode?
