Dual ACS 1121 setup Certificate help

[midsouthgeek]

I have two acs1121 appliances. Version : 5.2.0.26 Internal Build ID : B.3075 One is primary and one is secondary. The primary has a geo trust cert. It can authenticate to AD and allow Wireless access on my controllers. I would like to add the secondary into the mix. Will I need to have a seperate certificate for the secondary? Will computers authenticate with two seperate certs in a round robin senerio?

Thats for any help.

Yes you will need a separate certificate for the Secondary ACS server. Computers will authenticate with whichever ACS server is defined as the Primary AAA server under the WLAN on WLC.If your Primary ACS server goes down, WLC will utilize the Secondary ACS as a AAA server. However if you use a LoadBalancer, it can load balance radius requests between the two ACS servers, in which case both ACS's will be utilized.

Thanks,
