Configuring RADIUS Authentication and Accounting
Configuring the Switch for RADIUS Authentication
• 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. HP recommends
that you begin with the default (five seconds).
• Determine how many times you want the switch to try contacting a RADIUS server before trying another RADIUS
server or quitting. (This depends on how many RADIUS servers you have configured the switch to access.)
• Determine whether you want to bypass a RADIUS server that fails to respond to requests for service. To shorten
authentication time, you can set a bypass period in the range of 1 to 1440 minutes for non-responsive servers. This
requires that you have multiple RADIUS servers accessible for service requests.
