FTOS Configuration Guide for the C-Series - Force10 Networks

Configuration Task List for RADIUS
To authenticate users using RADIUS, at least one RADIUS server must be specified so that the system can
communicate with and configure RADIUS as one of your authentication methods.
The following list includes the configuration tasks for RADIUS.
• Defining a aaa method list to be used for RADIUS on page 147 (mandatory)
• Applying the method list to terminal lines on page 148 (mandatory except when using default lists)
• Specifying a RADIUS server host on page 148 (mandatory)
• Setting global communication parameters for all RADIUS server hosts on page 149 (optional)
• Monitoring RADIUS on page 150 (optional)
For a complete listing of all FTOS commands related to RADIUS, refer to the Security chapter in the
FTOS Command Reference.
Note: RADIUS authentication and authorization are done in a single step. Hence, authorization cannot be
used independent of authentication. However, if RADIUS authorization is configured and authentication is
not, then a message is logged stating this. During authorization, the next method in the list (if present) is
used, or if another method is not present, an error is reported.
To view the configuration, use the show config in the LINE mode or the show running-config command
in the EXEC privilege mode.
Defining a AAA method list to be used for RADIUS
To configure RADIUS to authenticate or authorize users on the system, you must create a AAA method
list. Default method lists do not need to be explicitly applied to the line, so they are not mandatory. To
create a method list, enter one of the following commands in CONFIGURATION mode:
Command Syntax Command Mode Purpose
aaa authentication login
method-list-name radius
aaa authorization exec
{method-list-name | default} radius
tacacs+
CONFIGURATION Enter a text string (up to 16 characters long) as the
name of the method list you wish to use with the
RADIUS authentication method.
CONFIGURATION Create methodlist with RADIUS and TACACS+ as
authorization methods. Typical order of methods:
RADIUS, TACACS+, Local, None. If authorization
is denied by RADIUS, the session ends (radius
should not be the last method specified).
