Timeout Specify the timeout period (between 1 and 300 seconds) before the ISG50

Key Enter a password (up to 15 alphanumeric characters) as the key to be shared

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”.
