4 Set the primary encryption key or secret. Use the following command:
This is the first key the RAS 1500 uses to encrypt passwords and the
RADIUS server uses to decrypt them. The RADIUS server(s) must be set to
the same secret (encryption) key. The encryption key is entered into the
clients file for the RADIUS server. The encryption key can be up to 15
characters long. See your RADIUS documentation for more information.
set authentication primary_secret <encryption key>
5 Optional. Set the secondary secret key. Use the following command:
set authentication secondary_secret <encryption key>
6 Set the number of retransmissions. This value is the total number of times
the RAS 1500 retransmits an authentication request to both primary and
secondary RADIUS servers. Use the following command:
set authentication retransmissions <count>
7 Set the UDP port to match the UDP port setting on the RADIUS server.
The default is 1645. Use the following command:
set authentication primary_port <port_number>
or
set authentication secondary_port <port_number>
8 Set the interval (in seconds) between retransmissions. Use the following
command:
set authentication timeout <number_seconds>
9 Configure authentication:
set ppp receive authentication [CHAP | PAP | either | none]
The following example configures authentication and saves the changes.
(Three separate commands are shown.)
set authentication type radius primary_server 3.3.3.2
secondary_server 3.3.3.4 primary_secret nuncio
secondary_secret pope retransmissions 3 timeout 60
primary_port 5555 secondary_port 5556
