Does anyone know if DHCP Option 43 is available on the Catalyst 3560G. I have 3 controllers and I want to make my 1130 series APs join the appropriate controller. I believe DNS is currently being used which is pushing all my APs to the same controller.
Does anyone of instructions on how to configue option 43 on the 3560?
Scott is right, they will still join on controller. To move the ap's to the correct controller, you either have to manually set the primary, secondary and or tertiary on each controller or if you have ECS, you can push out a template to specifice ap's.
The hard way using option 43 is that you stage certain ap's witha specific controller using option 43 then change the ip in the option 43 to the other controller and boot up the ap's for that. etc....
Within DHCP option 43 you can add any number of controller IP addresses. I have not tested if this works or not, but the premise is if the first controller in the list is not available it will use the next.
Once the AP has connected you will want to use WCS or manually configure the primary/secondary/tertiary controller on each AP. You could get away with not doing this (and allowing DHCP option to provide failover options) but failover time would increase, the AP would most likely need to reload to find another controller (again, untested).
