HP ProCurve Switch 6120G/XG Manual page 182

Note
If you want to configure RADIUS accounting on the switch, go to page 5-37:
"Configuring RADIUS Accounting" instead of continuing here.
Syntax: [no] radius-server host < ip-address > [oobm]
Adds a server to the RADIUS configuration or (with no)
deletes a server from the configuration. You can configure
up to three RADIUS server addresses. The switch uses the
first server it successfully accesses. (Refer to "Changing
the RADIUS Server Access Order" on page 5-50.)
For switches that have a separate out-of-band manage-
ment port, the oobm parameter specifies that the RADIUS
traffic will go through the out-of-band management
(OOBM) port.
[auth-port < port-number >]
Optional. Changes the UDP destination port for authenti-
cation requests to the specified RADIUS server (host). If
you do not use this option with the radius-server host
command, the switch automatically assigns the default
authentication port number. The auth-port number must
match its server counterpart. (Default: 1812)
[acct-port < port-number >]
Optional. Changes the UDP destination port for account-
ing requests to the specified RADIUS server. If you do not
use this option with the radius-server host command, the
switch automatically assigns the default accounting port
number. The acct-port number must match its server coun-
terpart.(Default: 1813)
