aironet 1142 wap with a controller

[mialbert]

I have an aironet 1142 wap that is at a branch site fronted by a c1900isr.  I'd like the wap to be configured by a controller that is at the main site and on a different subnet from the branch site.  I hooked the wap on a cross connection direct to the c1900isr router at the branch site.  The wap did not reach the controller to get a configuration.  Below is a log excerpt

This may look to be a dns issue, or does the main site controllers need to have the remote subnet defined in them first.

Can your WAP ping the Management IP address of the WLC?

Did you configure DNS and/or DHCP option 43?

What firmware is the controller running on?

[George Stefanick]

Also, what is the ip of your WLC?

[mialbert]

Yes i believe it can ping the wlc fine.  what kind of dns configuration am i going to need. 

[George Stefanick]

If the AP isn't finding the controller you can do one of the following:

Put the ap on the same vlan as the controller management

Configure option 43

Configure DNS

Configure IP Forward

The DNS config, you would create a A record for CISCO-CAPWAP-CONTROL and point it to your WLCs management IP address.

Yes i believe it can ping the wlc fine. 

Sorry, I don't take this answer.  It's either you can or you can't.  Please verify that you can.

And if you can, console into the WAP and enter this command "capwap ap controller ip address ".
