HP ProCurve 6120G/XG Manual page 227

Adds a server to the RADIUS configuration or (with no)
deletes a server from the configuration.
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 man­
agement (OOBM) port.
[acct-port < port-number >]
Optional. Changes the UDP destination port for
accounting requests to the specified RADIUS server. If
you do not use this option, the switch automatically
assigns the default accounting port number. (Default:
1813)
[key < key-string >]
Optional. Specifies an encryption key for use during
accounting or authentication sessions with the speci­
fied server. This key must match the encryption key
used on the RADIUS server. Use this command only if
the specified server requires a different encryption key
than configured for the global encryption key.
Note: When you save the config file using Xmodem
or TFTP, the key information is not saved in the
file. This causes Radius authentication to fail
when the config file is loaded back onto the switch.
(For a more complete description of the radius-server command and its
options, turn to page 5-14.)
