You can add up to ten RADIUS servers.

Enter the number of seconds AsyncOS stores the external authentication 
credentials before contacting the RADIUS server again to authenticate again in 
the “External Authentication Cache Timeout” field. Default is zero (0).

If the RADIUS server uses one-time passwords, for example passwords 
created from a token, enter zero (0). When the value is set to zero, 
AsyncOS does not contact the RADIUS server again to authenticate 
during the current session.
