Bridge > VLAN > Tagged VLAN
A VLAN is a group of ports that can be anywhere in the network, but communicate as
though they were in the same area.
VLANs can be easily organized to reflect department groups (such as R&D, Marketing),
usage groups (such as e-mail), or multicast groups (multimedia applications such as
video conferencing), and therefore help to simplify network management by allowing
users to move devices to a new VLAN without having to change any physical
connections.
1. Log into your switch
management page (see “
Access your switch management page
on page 7).
2. Click on
Bridge
, click on
VLAN,
and click on
Tagged VLAN
and then
Create New VLAN
.
3. Review the settings.
•
New VLAN ID
–
Enter the VLAN ID for the new VLAN.
•
Tag Settings
–
Clicking the icons under each port will change the member state
from Not Member, Tag egress packets, and Untag egress packets. Clicking the
All icon will change tag settings for all ports.
On a port, the tag information within a frame is examined when it is received to
determine if the frame is qualified as a member of a specific tagged VLAN. If it is, it is
eligible to be switched to other member ports of the same VLAN. If it is determined that
the frame’s tag does not conform to
the tagged VLAN, the frame is discarded. Since
these VLAN ports are VLAN aware and able to read VLAN VID tagged information on a
frame and forward to the appropriate VLAN, typically tagged VLAN ports are used for
uplink and downlink to other switches to carry and forward traffic for multiple VLANs
across multiple switches. Tagged VLAN ports can be included as members for multiple
VLANs. Computers and other edge devices are not typically connected to tagged VLAN
ports unless the network interface on these device can be enabled to be VLAN aware.
Select the tagged VLAN ports to add to the new VLAN.

Note:
By default, the default VLAN VID 1 is set as the Management VLAN.
4. Click
Apply
to save configuration changes to the NV-RAM to ensure that if the switch
is rebooted or power cycled, the configuration changes will still be applied.
5. The created Tagged VLANs will be displayed on the
Tagged VLAN
page. This switch
supports a maximum of 16 VLANs.
