RADIUS Authentication and Accounting
Configuring the Switch for RADIUS Authentication
[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)
[key < key-string >]
Optional. Specifies an encryption key for use during
authentication (or accounting) sessions with the specified
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 break when the
config file is loaded back onto the switch.
no radius-server host < ip-address > key
Use the no form of the command to remove the key for a
specified server.
For example, suppose you have configured the switch as shown in figure 6-3
and you now need to make the following changes:
1. Change the encryption key for the server at 10.33.18.127 to “source0127”.
2. Add a RADIUS server with an IP address of 10.33.18.119 and a server-
specific encryption key of “source0119”.
