Ok, I'm confused, I thought I had to have a local?
yes, just 2 controllers so just make one active master and another passive master and that's it? No locals?
So I would be sending AP's to just one controller under normal conditions?
is an active/active setup possible?
Here are your options with two controllers:
master-local or master-backup master
In master-local, you can have both controllers active, but only one controller, the master, has the ability to write and/or change the configuration. You can leverage additional capacity, but if the master goes down, the local can step in, but will be a read-only controller; you would have to change it to a master and reboot to regain write ability for your WLAN.
In master/backup master, only a single master is active at a time. Both controllers share a VRRP, or high availability address that all the access points terminate their traffic on. If the active master goes down, the backup master controller will take control of the high availability address and continue to pass traffic for those access points. The backup master becomes the active master, and you can make changes on your network.
Does that make sense?
