USER’S GUIDE AUTOMATIC TRANSFER SWITCH
100
RADIUS
RADIUS (Remote Authentication Dial-In User Service) is an authentication,
authorization, and accounting service. Use this option to centrally
administer remote access for each Automatic Transfer Switch.
When a user accesses the Automatic Transfer Switch, an authentication
request is sent to the RADIUS server to determine the user’s permission
level.
RADIUS user names are limited to 32 characters.
For more information on user permission levels, see Types of
user accounts.
RADIUS servers use port 1812 by default to authenticate
users. To use a different port, add a colon followed by the
new port number to the end of the RADIUS server name or
IP address.
