domain in cdp entry

Why is CDP showing a domain of on APs connected to my switch?  There is no "ip domain-name" configured on these controller-based APs.  APs have been rebooted since final download from controller.  Output of "sh cdp ne":
                 Gig 2/0/17        179                    AIR-LAP12 Gig 0
                 Gig 1/0/1         124                    AIR-LAP12 Gig 0
                 Gig 4/0/1         168                    AIR-LAP12 Gig 0
                 Gig 1/0/2         131                    AIR-LAP12 Gig 0
                 Gig 3/0/1         177                    AIR-LAP12 Gig 0

Probably just a default in the configuration. Configure your own domain name and it will show that.
I can see that you run a cisco WLC. The reason you see the domain is because of this.

The LWAPP communication is x509 certificate encrypted and signed with a key for the AP itself. However to create a key 2 things must be present.

1. A hostname
2. A Domain name

As a LWAPP AP isnt configurable before it has connected to the controller, via x509 communication, so the domain defaults to which is preconfigured for the AP certificate.

Hope this answers your question.

How do I get the APs to recognize the domain name configured in the switch that the controllers are in (this is a Cisco WiSM in a 6509)

Do you Provide your APs with an IP address from a DHCP server?
Define a hostname (hostname XXXX ) and set a new domain name (ip domain-name XXXX)  in your devices AND wireless controller.
Generate again the keys

This will solve your problem

APs use DHCP and Option 43 to get initial IP address and locate their controller.  APs are then named and assigned static IPs.
Yeah nevermind my comment about DHCP I was in "somewhere else than here land" when I wrote that.

I havnt tried it myself, but cant think of a reason why is shouldnt work, to do what ampranti says if the commands are available.
