RADIUS Authentication, Authorization, and Accounting

General RADIUS Setup Procedure

General RADIUS Setup ProcedurePreparation:

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), web browser interface 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.

Note: The Webui 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.

•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.

•Determine an acceptable timeout period for the switch to wait for a server to respond to a request. ProCurve recommends that you begin with the default (five seconds).
