information with other devices. For example, with GVRP function enabled
on two switches, the switches are able to automatically exchange the
information of their VLAN database. Therefore, the administrator doesn’t
need to manually configure whether the link is trunk or hybrid, the
packets belonging to the same VLAN can communicate across switches.
Mark this checkbox to enable GVRP protocol. This checkbox is available
while the VLAN Operation Mode is in 802.1Q mode.

Port

To select the port you want to configure

Link Type

This feature allows the administrator to decide a certain port to be an
Access Link, a Trunk Link, or a Hybrid Link.
¾

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 considered as the same VLAN group members.

¾

Trunk Link: A segment which provides the link path for one or more

VLAN-aware devices (switches). A Trunk Port, connected to the trunk
link, has an understanding of tagged frame, which is used for the
communication among VLANs across switches. Which frames of the
specified VIDs will be forwarded depend on the values filled in the
Tagged VID column field. Please insert a comma between two VIDs.

¾

Hybrid Link: A segment which consists of Access and Trunk links. The

hybrid port has both the features of access and trunk ports. A hybrid
port has a PVID belonging to a particular VLAN, and it also forwards
the specified tagged-frames for the purpose of VLAN communication
across switches.

Untagged VID

This column field is available when Link Type is set as Access Link or
Hybrid Link. Assign a number ranging from 1 to 4094.

Tagged VID

This column field is available when Link Type is set as Trunk Link or
Hybrid Link. Assign a number ranging from 1 to 4094.

After finishing necessary configurations, click on Apply to save the settings.

Since the access port doesn’t have an understanding of tagged frames, the column field of
Tagged VID will not be available when the port is configured as an Access Link.

1. A trunk port doesn’t insert tag into an untagged frame, and therefore the untagged VID

column field is not available when the port is configured as a Trunk Link.

2. It’s not necessary to type ‘1’ in the tagged VID. The trunk port will forward the frames of

VLAN 1.

3. The trunk port has to be connected to a trunk/hybrid port of the other switch. Both the

tagged VID of the two ports have to be the same.

1. It’s not necessary to type ‘1’ in the tagged VID. The hybrid port will forward the frames of

VLAN 1.

2. The hybrid port has to be connected to a trunk/hybrid port of the other switch. Both the

tagged VID of the two ports have to be the same.
