TRENDnet User's Guide
The VLAN table displays the current list of VLANs. By default, all ports are assigned as
untagged members of VLAN ID 1. The color code on each port indicates the type of
membership for each port assigned to a specific VLAN. Up to 32 VLANs can be created.

Untagged port member – Green

Tagged port member – Orange

Non- member or restricted port - Gray

VLAN ID – Displays the VLAN ID.

Modify – Click modify to edit the VLAN configuration. The default VLAN cannot
be modified.

Delete – Click delete to delete the VLAN. The default VLAN cannot be deleted.

Management VLAN – Click the drop-down list and select Enabled to allow
access to the switch management page through the new VLAN. If you want to
restrict management access through this VLAN, select Disabled.
Note: By default, the default VLAN VID 1 is set as the Management VLAN.
To create a new VLAN, click Create New VLAN.
Enter the VLAN ID to assign to the new VLAN. (ex. ID 100)
By default, all ports are set as tagged members of the new VLAN.
To change the port membership to untagged or non-member, click on the port box
multiple times to cycle through the port membership type based on the color code.

After you have assigned all the ports with the desired port membership to the new
VLAN, click Apply.
Note: when untagged or VLAN-unaware ports are assigned to a VLAN, the port VLAN ID
should be assigned the same ID as the VLAN to be properly configured. (ex. If adding
ports 7 & 8 as untagged port members of VLAN ID 100, the PVID assignment for ports 7
& 8 should be set to 100.)
Tagged/Untagged/Non-Member VLAN 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.
