4.4.12 Advanced Settings > VLAN > 802.1Q 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 tosimplify network management by allowing users to move devices to a new VLAN without having to
changeany physical connections.
By default, 802.1Q VLAN is disabled. With 802.1Q VLAN enabled, the VLAN VID 1 is created by default
with an empty VLAN name field and all ports are configured as
“ Untagged ” members.
The 802.1Q VLAN configuration is accomplished in following steps:
• Creating a new VID group
• Assigning ports as Access or Trunk.
• Configuring the PVID of access VLAN
• Advanced Settings > VLAN > 802.1Q VLAN : Click Apply to create a new VID group.
• Advanced Settings > VLAN > 802.1Q VLAN Port Setting > Edit : Change the Port VLAN Mode
act as Access or Trunk.
• PVID settings : Port VLAN ID (PVID) is an identification that encompasses a particular switch
port ’ s identification and VLAN membership. This identification is used to classify the incoming
untagged frames.
• Click Edit to configure the PVID of a port.
Delete : Click to delete the VLAN group.
