Chapter 8 RADIUS

N4100 User’s Guide

Shared Secret 
Key

Enter a password (up to 64 characters) as the key to be shared between 
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/
Domain Name 

Enter the IP address or the domain name of the RADIUS server.

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 
Key

Enter a password (up to 64 characters) as the key to be shared between 
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.

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.

Accounting 
Service

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.
