Cisco AAA Radius Server Group question

[emilyforcisco1]

In the Cisco Air CT5760, when configuring a Radius Server Group, in AAA Security, are the "Assigned Servers" to the group used in "Round Robin", or does the authentication always use the top one unless it is "Offline"?

I can't seem to find any info on this from Cisco.

Hi,

First server in the list of Assigned server will always be used for serving AAA request until and unless it gets down or offline then it will Fallback to next server.

There is one more option in WLC called "aggressive failover" where primary server will be in use again if it got active again.
