RADIUS Authentication and Accounting
General RADIUS Setup Procedure
General RADIUS Setup Procedure
Preparation:
1. Configure one to three RADIUS servers to support the switch. (That is,
one primary server and one or two backups.) Refer to the documentation
provided with the RADIUS server application.
2. Before configuring the switch, collect the information outlined below.
Table 5-1. Preparation for Configuring RADIUS on the Switch
• Determine the access methods (console, Telnet, Port-Access (802.1X), SSH, and/or web browser interface) 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 5-1. 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 three 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.

Webui, Web-Auth, and Mac-Auth access is available on the 2600, 2600-PWR,
and 2800 switches (not on the 4100 and 6108 switches).
