6.3 Introduction to VLANs

A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.

In MTU (Multi-Tenant Unit) applications, VLAN is vital in providing isolation and security among the
subscribers. When properly configured, VLAN prevents one subscriber from accessing the network

Time Zone

Select the time difference between UTC (Universal Time Coordinated, formerly known as
GMT, Greenwich Mean Time) and your time zone from the drop-down list box.

Daylight Saving
Time

Daylight saving is a period from late spring to early fall when many countries set their
clocks ahead of normal local time by one hour to give more daytime light in the evening.

Select this option if you use Daylight Saving Time.

Start Date

Configure the day and time when Daylight Saving Time starts if you selected Daylight
Saving Time. The time is displayed in 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 2:00.

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
and the last field depends on your time zone. In Germany for instance, you would select
2:00 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 Daylight
Saving Time. The time field uses the 24 hour format. Here are a couple of examples:

Daylight Saving Time ends in the United States on the last Sunday of October. 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 and the last field depends on your time zone. In Germany for instance, you
would select 2:00 because Germany's time zone is one hour ahead of GMT or UTC
(GMT+1).
