Catalyst Express 500 error

we have an AP in a port and every few days we get an error that reads "Port XX: Dynamic Host Configuration Protocol (DHCP) reply messages dropped for non-existing or disconnected devices on this interface."

Recommendation is "Reconnect the device. Check if unauthorized device is connected to this network. Disconnect the unauthorized device.

No matter what port we plug the AP in, we'll get this message. We've assigned SmartRoles on the ports and we still get it. Any thoughts?

Re: Catalyst Express 500 error

1.Is this message coming at regular interval ?

2.If it is not coming at regular interval , then it looks like some unauthorized device trying to connect through wireless network ..

HTH..rate if helpful..
