7.5 Technical Reference
This section provides some technical information about the topics covered in this
chapter.
7.5.1 Administrator Authentication on RADIUS
The administrator authentication on RADIUS feature lets a (external or internal)
RADIUS server authenticate management logins to the NWA. This is useful if you
need to regularly change a password that you use to manage several NWAs.
Activate administrator authentication on RADIUS in the System > Password
screen and configure the same user name, password and RADIUS server
information on each NWA. Then, whenever you want to change the password, just
change it on the RADIUS server.
7.5.2 Pre-defined NTP Time Servers List
When you turn on the NWA for the first time, the date and time start at 2000-01-
01 00:00:00. When you select
Auto in the System > Time Setting screen, the
NWA then attempts to synchronize with one of the following pre-defined list of
NTP time servers.
End Date Configure the day and time when Daylight Saving Time ends if you
selected
Enable Daylight Saving . The o'clock field uses the 24
hour format. Here are a couple of examples:
Daylight Saving Time ends in the United States on the first Sunday
of November. Each time zone in the United States stops using
Daylight Saving Time at 2 A.M. local time. So in the United States
you would select
First , Sunday , November and 2:00 .
Daylight Saving Time ends in the European Union on the last
Sunday of October. All of the time zones in the European Union
stop using Daylight Saving Time at the same moment (1 A.M. GMT
or UTC). So in the European Union you would select
Last ,
Sunday , October . The time you type in the at field depends on
your time zone. In Germany for instance, you would type 2
because Germany's time zone is one hour ahead of GMT or UTC
(GMT+1).
