AAA Server Groups

You can specify remote AAA servers for authentication, authorization, and accounting using server
groups. A server group is a set of remote AAA servers that implement the same AAA protocol. The
purpose of a server group is to provide for failover servers in case a remote AAA server fails to respond.
If the first remote server in the group fails to respond, the next remote server in the group is tried until
one of the servers sends a response. If all the AAA servers in the server group fail to respond, then that
server group option is considered a failure. If required, you can specify multiple server groups. If a
Nexus 5000 Series switch encounters errors from the servers in the first group, it tries the servers in the
next server group.

If the method is for all RADIUS servers, instead of a specific server group, the Nexus 5000 Series
Note
switches choose the RADIUS server from the global pool of configured RADIUS servers in the order of
configuration. Servers from this global pool are the servers that can be selectively configured in a
RADIUS server group on the Nexus 5000 Series switches.

The accounting log for all switches in the fabric can be centrally managed.
User attributes for each switch in the fabric than using the local databases on the switches are easier
to manage.
