request to a RADIUS server. At the end of
the timeout period, if no connection has been
established, authentication will fail.
• interval is an integer that indicates
the time interval in seconds (s), minutes
(m), or hours (h). If you do not specify a
measurement unit, seconds is assumed.
The range is 1–10000 seconds. The default
is 10 seconds.
fallback on|off
Specifies the desired fallback mode. Valid
options are:
•
on—if the RADIUS servers are
unreachable, the local passwords defined
on the Nortel SNAS are used as fallback
• off—if the RADIUS servers are
unreachable, the only way to access
the system is to reinstall the software (boot
install)
The default is on.
ATTENTION
With the fallback mode set to on, unwanted
access to the Nortel SNAS is possible
using a serial cable if the network cable
is disconnected and the local password is
known.
