Configuring User Authentication Security
176 Perle 833IS User Guide
Authentication Protocol
Selects the Authentication protocol to be used between the 833IS and the RADIUS
server. Click on the check box to enable CHAP or PAP authentication protocols. If
both are checked, the 833IS will first attempt to retrieve the user name and password
using CHAP. If CHAP is not supported by the client, it will then use PAP.
IP Address
The Internet Protocol address of the RADIUS server.
UDP port
The UDP port to be used to communicate with the RADIUS server. The default is
1812 for an authentication server and 1813 for an accounting server.
Secret
The secret key that is shared between the 833IS and the RADIUS server to encrypt
the data. This key must match the key configured on the RADIUS server.
Timeout Value
The length of time in seconds for the 833IS to wait for a reply from the RADIUS
server. The default is 3 seconds.
Number of Retries
The number of times the 833IS will retry a request if no answer is received from the
RADIUS server. The default value is 2.
The user is not required to configure a backup RADIUS authentication server, a
RADIUS accounting server or a backup RADIUS accounting server. If an
accounting RADIUS server is not configured, the accounting information will be
forwarded to the authentication RADIUS server.
For a complete list of the RADIUS server attributes supported by the 833IS, please
refer to “Appendix 4: RADIUS Server Attributes”.
Axent
Axent (previously known as Assurenet or Digital Pathways) is a software based
security server that provides user authentication with SecureNet Key cards. When
the remote Client connects, the 833IS will ask the Axent server to start the
authentication process. The 833IS then acts as a path between the remote Client and
the Axent server. The remote Client enters a TTY or terminal mode. The Axent
server will then prompt the Dial-In user for their user ID and security token from the
