• Use Delete  to delete the VLAN. 
• Use  Edit  to modify group name, VLAN ID, or add/remove the members of the existing VLAN group. 
 
Note 
Remember to execute the “Save Configuration” action, otherwise the new 
configuration will lose when switch power off. 
 
 
802.1Q VLAN 
 
Tagged-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. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers. 
You can create Tag-based VLAN, and enable or disable GVRP protocol. There are 256 VLAN groups to 
provide configuration. Enable 802.1Q VLAN, all ports on the switch belong to default VLAN of VID 1. The 
default VLAN can’t be deleted. 
 
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. 
GVRP is based on GARP (Generic Attribute Registration Protocol), a protocol that defines procedures by 
which end stations and switches in a local area network (LAN) can register and de-register attributes, 
such as identifiers or addresses, with each other. 
Every end station and switch thus has a current record of all the other end stations and switches that can 
be reached.
