I keep having these Errors on a Cisco 3750, only thing on this switch is APs.

Could this be why the AP are so hit or miss or keep messing up and If so what would be a good way to fix this?

Thank you

This normal if wifi client do roaming 

You can use 

No mac address notify mac move

Hi,

It appears that you have some sort of loop on the network, because the same MAC address shows up on multiple physical ports. Are all the APs connected to this switch using a single link or multiple? Are you using any hubs anywhere on the network?

Also, on your trunk ports to APs, it is always a good idea to allow only the vlans that need to be on the trunk port and not all vlans.

switchport trunk allowed vlan x, y, z
