Security Management RADIUS
4. Define the Method of access to the ML device:
Local (ML factory default) - access is verified according to the user information
stored in the ML device.
Radius and Local - the Radius server (including backup Server) and then locally
stored on ML user information is queried for authentication.
Radius - only the Radius can authenticate access. If the Radius is not available, then
access the ML is not allowed.
5. If a backup Radius Server exists, under Backup Server:
Check-mark the Enable option
Enter the IP address of the backup Radius Server.
NOTE: If a backup server is not defined (0.0.0.0 by default) query is skipped. If both
Servers are configured with the same IP, queries will be sent twice (if no reply from
Primary Server).
