DHCP using different subnet

Ok....I'm trying to get a guest network up and running.  I have all of my APs statically assigned in one subnet and want to use one of the APs as a DHCP server handing out addresses using a different subnet.  Is this possible?  If so, how do I set it up.  Right now, I have the server and the relay setup, but it is telling me I can't have the  server ip be the same as the management interface (which is the static IP of the AP that I want to use as a DHCP server) Any help would be great. Thanks.

That's correct - you cannot have the server IP and the mgt0 IP be the same. For an AP to be a DHCP server, it needs to consume 2 addresses in the scope... 1 for mgt0, the other for that DHCP server object.

There isn't a separate document just for this, but it is explained in the DHCP Servers & Relay Agents Help topic. See the "Adding a New DHCP Server Configuration" section where you'll find a description for the situation you're describing; that is, for configuring an AP to be a DHCP server for clients in multiple VLANs.
