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 link types.

 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.

Note: Because the access port doesn’t have an understanding of tagged frame, the column

field of Tagged VID is not available.

 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

depends on the values filled in the Tagged VID column field. Please insert a

comma between two VIDs.

Note:

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

column field is not available.

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.
