Hi Ric

Thanks for the reply the AP was working fine prior to changing the switch, DHCP comes via our DHCP server in our DC downstairs, I have taken the AP off the ceiling and plugged it into a spare port at my desk and it works fine when clients connect they get an IP address without issue (different switch) Unfortunately I do not have the config for the Enterasys as it has been utilized elsewhere after wiping it.

Port detail below AP is set up on the DATA vlan

Could you please connect the client again to the SSID and then run the following on the switch....

show port 47 vlan
show fdb | i 47

Also please provide the AP and client MAC.
