Chapter 8 RADIUS Table 12 ADVANCED > RADIUS LABEL DESCRIPTION Shared Secret Enter a password (up to 64 characters) as the key to be shared between Key the RADIUS server and the N4100. The key is not sent over the network. This key must be the same on the RADIUS server and the N4100. Secondary RADIUS Server Server IP/ Enter the IP address or the domain name of the RADIUS server. Domain Name Authentication Port Enter the port number that the RADIUS server uses for authentication. You only need to change this value from the default if your network administrator gave you a specific port number to use. The allowed numbers are from 0 to 65535. Accounting Port Enter the port number that the RADIUS server uses for accounting. You only need to change this value from the default if your network administrator gave you a specific port number to use. The allowed numbers are from 0 to 65535. Shared Secret Enter a password (up to 64 characters) as the key to be shared between Key the RADIUS server and the N4100. The key is not sent over the network. This key must be the same on the RADIUS server and the N4100. Retry times when Primary fail At times the N4100 may not be able to use the primary RADIUS server. Select the number of times the N4100 should reattempt to use the primary RADIUS server before attempting to use the secondary RADIUS server. This also sets how many times the N4100 will attempt to use the secondary RADIUS server. For example, you set this field to 3. If the N4100 does not get a response from the primary RADIUS server, it tries again up to three times. If there is no response, the N4100 tries the secondary RADIUS server up to three times. Accounting Service If there is also no response from the secondary RADIUS server, the N4100 stops attempting to authenticate the subscriber. The subscriber will see a message that says the RADIUS server was not found. Select Disable if you will not use an external RADIUS server to perform accounting for the wireless client accounts. Select Enable to use an external RADIUS server to perform accounting for the wireless client accounts. Interim Update Time Specify the time interval for how often the N4100 is to send a subscriber status update to the RADIUS server. Authentication Method Enter the authentication protocol that the RADIUS server uses. PAP (Password Authentication Protocol) requires users to enter a password before accessing a secure system. The user's name and password are sent over the wire to a server where they are compared with a database of user account names and passwords. CHAP (Challenge Handshake Authentication Protocol) avoids sending passwords over the wire by using a challenge/response technique. 96 N4100 User's Guide
