RADIUS Authentication, Authorization, and Accounting
Configuring the Switch for RADIUS Authentication
Using Multiple RADIUS Server Groups
The authentication and accounting features on the switch can use up to fifteen
RADIUS servers. This option allows the RADIUS servers to be put into groups.
Up to 5 groups of 3 RADIUS servers each can be configured. The authentica-
tion and accounting features can choose which RADIUS server group to
communicate with. End-user authentication methods (802.1X, MAC-based
and web-based) can authenticate with different RADIUS servers from the
management interface authentication methods (console, telnet, ssh, web).
Commands
Several commands are used to support the RADIUS server group option. The
RADIUS server must be configured before it can be added to a group. See
“Configuring the Switch for RADIUS Authentication” on page 6-6 for more
information about configuring RADIUS servers.

Because the radius-server command includes an
acct-port keyword with a non-default UDP port
number of 1750, the switch assigns this value as the
UDP accounting port.
Syntax: [no] radius-server host < ip-address >
Adds a server to the RADIUS configuration or (with no ) deletes
a server from the configuration. You can configure up to
fifteen RADIUS server addresses. The switch uses the first
server it successfully accesses.
