4-6.11.2 IEEE 802.1Q Tag-based VLAN
Tag-based VLAN is an IEEE 802.1Q standard which allows to create a VLAN across devices from different
switch venders. IEEE 802.1Q VLAN uses a technique to insert a “tag” into the Ethernet frames. Tag contains
a VLAN Identifier (VID) that indicates the VLAN numbers.
All ports on the switch belong to default VLAN, VID is 1. The default VLAN can’t be deleted. The maximum
VLAN group is up to 64.
Virtual Local Area Network (VLAN) can be implemented on the switch to logically create different broadcast
domain.
When the 802.1Q VLAN function is enabled, all ports on the switch belong to default VLAN of VID 1, which
means they logically are considered as members of the same broadcast domain. The valid VLAN ID number
ranges from 1 to 4094. The amount of VLAN groups is up to 256 including default VLAN that cannot be
deleted.
Each member port of an 802.1Q VLAN group is on either an Access Link (non VLAN-tagged) or a Trunk Link
(VLAN-tagged). All frames on an Access Link carry no VLAN identification, while all frames on a Trunk Link
are VLAN-tagged. In addition to above-mentioned 2 types, there is the third mode—Hybrid. A Hybrid Link
can carry both VLAN-tagged frames and untagged frames. A single port is supposed to belong to one VLAN
group, except it is on a Trunk/Hybrid Link.
The technique of 802.1Q tagging inserts a 4-byte tag, including VLAN ID of the destination port—PVID, in
the frame. With the combination of Access/Trunk/Hybrid Links, the communication across switches also can
make the packet sent through tagged and untagged ports.
4-6.11.2.1 802.1Q Configuration
VLAN Operation Mode
Select 802.1Q from the drop down list to configure Tag-based VLAN
settings.
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, meaning this limit is not enabled (all members in
different VLANs can access this switch).
Enable GVRP
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
