I bought Deploying and Troubleshooting Cisco Wireless LAN controllers last month and I'm reading it. On page 52 it states that I have to configure option 60 in my DHCP scope in order for my scope to deliver option 43 to the access point in order for it to be able to find the controller. It also states that one DHCP scope can only support one access point type.
I have my scopes built and they work flawlessly without option 60. I have scopes all similar to this:
ip dhcp pool AP_VLAN
network 10.127.103.0 255.255.255.0
dns-server 10.10.10.10 (name changed to protect the innocent)
option 43 hex f140.0a81.ff0b.0a81.ff0c.(this list goes on for a total of 16 controllers)
None of my controllers are on the 10.127.0.0 network, so they need the option to find the controllers. I have Cisco 1142s, 1252s, 1240s and 1230s on these DHCP scopes/segments, and they all work just fine. - without any DHCP option 60 set anywhere.
Can anyone explain this for me?
