Configuring RADIUS Authentication and Accounting

Outline of the Steps for Configuring RADIUS Accounting

1.

Configure the switch for accessing a RADIUS server.

You can configure a list of up to three RADIUS servers (one primary, two backup). The switch 
operates on the assumption that a server can operate in both accounting and authentication 
mode. (Refer to the documentation for your RADIUS server application.) 

•

Use the same 

radius-server host command that you would use to configure RADIUS 

•

Provide the following:

–

A RADIUS server IP address.

–

Optional—a UDP destination port for authentication requests. Otherwise the switch 
assigns the default UDP port (1812; recommended).

–

Optional—if you are also configuring the switch for RADIUS authentication, and 
need a unique encryption key for use during authentication sessions with the  
RADIUS server you are designating, configure a server-specific key. This key over-
rides the global encryption key you can also configure on the switch, and must match 
the encryption key used on the specified RADIUS server. For more information, refer 
to the "

[key < key-string >]" parameter on page 109. (Default: null)

2.

Configure the types of accounting you want the switch to perform, and the controls for sending 
accounting reports from the switch to the RADIUS server(s). 

•

•

 At session start and 

stop or only at session stop

3.

(Optional) Configure session blocking and interim updating options

•

 Periodically update the accounting data for sessions-in-progress

•

 Block the accounting session for any unknown user with no 

username accesses the switch
