User Guidelines
Assigning a name to multiple RADIUS servers associates the servers into a
list. Server groups may be used to control which authentication servers are
prioritized for traffic.
Names may consist of alphanumeric characters and the underscore, dash and
blanks. Embed the name in double quotes to use a name with blanks.
NOTE:
When multiple RADIUS servers are configured with different list names, e.g.
ServerName is name1 and address is 1.1.1.1 ServerName is name2 and address is 1.1.1.2
the RADIUS request is always sent to the first lexicographically ordered server list, i.e.
communication with the name1 server list is attempted before moving on to the name2
server list. Even if the priority value of servers in the name2 list is lower (lower value
indicates higher priority) the request is sent to the name1 servers. If no servers respond in
the name1 list, the request is sent to the second name list in lexicographic order, et. seq.
A server group may consist of multiple primary server and multiple secondary
servers. Within a server group, communication the primary servers is
attempted first in priority order. From the multiple secondary servers, the
server with the lowest priority value is tried after the primary fails. For a server
group where all priorities are equal, communication is attempted based on
the server name lexicographic order. For example, if name9, name1, name6
are configured in a server group, communication is attempted in the order
name1, then name6, then name9.
Use the show aaa servers name command to display the server groups.
