802.1Q VLAN
Tag-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible 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. The Tag contains a VLAN Identifier
(VID) that indicates the VLAN numbers.
You can create a Tag-based VLAN, and enable or disable GVRP protocol. There are
256 VLAN groups. If 802.1Q VLAN is Enabled then all ports on the switch belong to the
default VLAN, VID is 1. The default VLAN can’t be deleted.
GVRP allows automatic VLAN configuration between the switch and nodes. If the switch
is connected to a device with GVRP enabled, you can send a GVRP request using the
VID of a VLAN defined on the switch; the switch will automatically add that device to the
existing VLAN.
