I am running ArubaOS 6.1.3.6 on M3 modules (6000 series controller) in different geographic locations setup in a master/local configuration. All locations use the same VAPs, but different AP Groups. We currently use the same radius server group for the VAPs across all geo locations. However, we want to add a radius server at one location and have the APs in that AP group use that local radius as the primary radius server and a radius server in the original location as the backup radius server. Is there a way to do this with the same VAPs in different locations?
