RADIUS Authentication, Authorization, and Accounting
General RADIUS Setup Procedure
General RADIUS Setup Procedure
Preparation:
1. Configure one to fifteen RADIUS servers to support the switch. Refer to
the documentation provided with the RADIUS server application.
2. Before configuring the switch, collect the information outlined below.
Table 6-1. Preparation for Configuring RADIUS on the Switch
• Determine the access methods (console, Telnet, Port-Access (802.1X), WebAgent and/or SSH) for which you want
RADIUS as the primary authentication method. Consider both Operator (login) and Manager (enable) levels, as well
as which secondary authentication methods to use (local or none) if the RADIUS authentication fails or does not
respond.
Figure 6-1. Example of Possible RADIUS Access Assignments
• Determine the IP address(es) of the RADIUS server(s) you want to support the switch. (You can configure the switch
for up to fifteen RADIUS servers.)
• If you need to replace the default UDP destination port (1812) the switch uses for authentication requests to a specific
RADIUS server, select it before beginning the configuration process.
• If you need to replace the default UDP destination port (1813) the switch uses for accounting requests to a specific
Radius server, select it before beginning the configuration process.
• Determine whether you can use one, global encryption key for all RADIUS servers or if unique keys will be required
for specific servers. With multiple RADIUS servers, if one key applies to two or more of these servers, then you can
configure this key as the global encryption key. For any server whose key differs from the global key you are using,
you must configure that key in the same command that you use to designate that server’s IP address to the switch.

Note: The WebAgent
access task shown in this
figure is available only on
the switches covered in
this guide.
Console access requires
Local as secondary
method to prevent lockout
if the primary RADIUS
access fails due to loss of
RADIUS server access or
other problems with the
server.
