Start Date
Configure the day and time when Daylight Saving Time starts if you selected
Enable Daylight Saving
. The
o'clock
field uses the 24 hour format. Here are a
couple of examples:
Daylight Saving Time starts in most parts of the United States on the second
Sunday of March. Each time zone in the United States starts using Daylight
Saving Time at 2 A.M. local time. So in the United States you would select
Second
,
Sunday
,
March
and type 2 in the
o'clock
field.
Daylight Saving Time starts in the European Union on the last Sunday of March.
All of the time zones in the European Union start using Daylight Saving Time at
the same moment (1 A.M. GMT or UTC). So in the European Union you would
select
Last
,
Sunday
,
March
. The time you type in the
o'clock
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).
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:

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 type 2 in the
o'clock
field.
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

. The time you type in the

Logs
20.1
Overview
This chapter contains information about configuring general log settings and viewing the
ZyXEL Device’s logs.
The web configurator allows you to choose which categories of events and/or alerts to have
the ZyXEL Device log and then display the logs or have the ZyXEL Device send them to an
administrator (as e-mail) or to a syslog server.
20.1.1
What You Can Do in the Log Screens
•
Use the
View Log
screen (
Section 20.2 on page 275
) to see the logs for the categories that
you selected in the
Log Settings
screen.
•
Use The
Log Settings
screen (
Section 20.3 on page 276
) to configure the mail server, the
syslog server, when to send logs and what logs to send.
20.1.2
What You Need To Know About Logs
Alerts
An alert is a message that is enabled as soon as the event occurs. They include system errors,
attacks (access control) and attempted access to blocked web sites. Some categories such as
System Errors
consist of both logs and alerts. You may differentiate them by their color in the
View Log
screen. Alerts display in red and logs display in black.
Logs
A log is a message about an event that occurred on your ZyXEL Device. For example, when
someone logs in to the ZyXEL Device, you can set a schedule for how often logs should be
enabled, or sent to a syslog server.
20.2
The View Log Screen
Use the
View Log
screen to see the logs for the categories that you selected in the
Log
Settings
screen (see
Section 20.3 on page 276
). Click
Maintenance > Logs
to open the
View
Log
screen.
Entries in red indicate alerts. The log wraps around and deletes the old entries after it fills.
Click a column heading to sort the entries. A triangle indicates ascending or descending sort
order.
