(per official RADIUS assigned ports)

Note: RADIUS packages are available for all major Linux distributions.
When you communicate with the RADIUS server, use a shared secret of your choosing
to:
• Authenticate the SMS2000 with the RADIUS server.
• Verify responses returned from the RADIUS server to the SMS2000.
Note:
The auth add radius command does not automatically assume that the
same RADIUS server (with the same name and secret) is used for accounting,
you must configure it with these settings using the acct add command.

primary-only=times] [timeout=seconds] [deadtime=minutes] [alias]
