802.1Q Configuration
 Pull down the selection item and focus on 802.1Q then press to set the
VLAN Operation Mode in 802.1Q mode.
 Enable GVRP Protocol: GVRP (GARP VLAN Registration Protocol) is a protocol
that facilitates control of virtual local area networks (VLANs) within a larger network.
GVRP conforms to the IEEE 802.1Q specification, which defines a method of
tagging frames with VLAN configuration data. This allows network devices to
dynamically exchange VLAN configuration information with other devices. For
example, having enabled GVRP on two switches, they are able to automatically
exchange the information of their VLAN database. Therefore, the user doesn’t need
to manually configure whether the link is trunk or hybrid, the packets belonging to the
same VLAN can communicate across switches. Tick this checkbox to enable GVRP
protocol. This checkbox is available while the VLAN Operation Mode is in 802.1Q
mode.
 Management VLAN ID: Only when the VLAN members, whose Untagged VID
(PVID) equals to the value in this column, will have the permission to access the
switch. The default value is ‘0’ that means this limit is not enabled (all members in
different VLANs can access this switch).
 Select the port you want to configure.
 Link Type : There are 3 types of link type.
 Access Link: A segment which provides the link path for one or more stations
to the VLAN-aware device. An Access Port (untagged port), connected to the
access link, has an untagged VID (also called PVID). After an untagged frame
gets into the access port, the switch will insert a four-byte tag in the frame. The
contents of the last 12-bit of the tag is untagged VID. When this frame is sent
out through any of the access port of the same PVID, the switch will remove the
tag from the frame to recover it to what it was. Those ports of the same
untagged VID are regarded as the same VLAN group members.
