Cisco WLC and AP DHCP Options

For Cisco AP's to get registered to a WLAN Controller on a different subnet, you have to do a bit of work on your DHCP server. This is where it gets interesting.

I found an article online from Cisco that you can follow to get these AP's working with your WLC. You can find that article here.

The one thing I did differently in the Predefined Options was instead of using Binary in the data type, I used IP Address and then edited the Array to include the IP Address of the WLC. Then in the scope options, the IP address has been specified and is good to go.

The AP gets the Option 43 to get the files from the WLC and then registers after any firmware upgrade the controller could be offering.

All set and good to go.
