Suggestion for 2nd master controller (not redundancy master)

Hi Everyone,

I am trying to setup a 2nd master controller for a group of APs. We have aruba-master in our DNS for AP groups that talk to main master controller. So my question is how I can accomplish this by not manually configuring the 2nd master ip address in the each AP? I have 1st master and 2nd master are in the same network, and AP groups are in different network but APs getting IP from the same dhcp servers. I have tried the dhcp option 43 for 2nd master AP group but it does not work quite well, perhaps its dhcp issue I have dig into it. But I just wondering does anyone have different approach or share information about dhcp option? Thanks for any comment and suggestions.

Best Regards,

DHCP option 43 should be working, many customers use that. Your other option is to configure sub-domains, such as and You could then have, etc., but that's probably a bigger headache than figuring out your DHCP issue. You should probably consider moving away from DNS if you do DHCP just to keep things consistent.
