Port
Specify the port number on the RADIUS server to which the ISG50 sends 
authentication requests. Enter a number between 1 and 65535. 
Timeout
Specify the timeout period (between 1 and 300 seconds) before the ISG50 
disconnects from the RADIUS server. In this case, user authentication fails. 
Search timeout occurs when either the user information is not in the RADIUS 
server or the RADIUS server is down. 
Key
Enter a password (up to 15 alphanumeric characters) as the key to be shared 
between the external authentication server and the ISG50. 
The key is not sent over the network. This key must be the same on the external 
authentication server and the ISG50. 
Group 
Membership 
Attribute
A RADIUS server defines attributes for its accounts. Select the name and number 
of the attribute that the ISG50 is to check to determine to which group a user 
belongs. If it does not display, select user-defined and specify the attribute’s 
number.  
This attribute’s value is called a group identifier; it determines to which group a 
user belongs. You can add ext-group-user user objects to identify groups based 
on these group identifier values. 
For example you could have an attribute named “memberOf” with values like 
“sales”, “RD”, and “management”. Then you could also create a ext-group-user 
user object for each group. One with “sales” as the group identifier, another for 
“RD” and a third for “management”.
