MAC FLAPPING

How to stop MAC flapping?

On what ports? If you see it on AP ports that have a ssid in bridge mode its expected behavior. (Clients moving from AP to AP)

Thank you! Yes we have checked this and some mac addresses seem to roam around APs which caused the flapping

As ww has stated if those are mac addresses from wireless clients and you have alot of roaming then you won't be able to get rid of these warnings.  Catalyst switches also exhibit this so I guess the default timewindow switches use to determine if a mac is flapping might be too long.

Thank you! This is of great help
