VLAN
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain, allows
the isolation of network traffic. Only the members of the VLAN will receive traffic from the
same members of VLAN. Basically, creating a VLAN from a switch is the logical equivalent of
reconnecting a group of network devices to another Layer 2 switch. However, all the network
devices are still physically plugged into the same switch.
The switch supports 802.1Q (tagged-based) VLAN. The default configuration of VLAN operation
mode is at
802.1Q
.
VLAN Configuration — 802.1Q
Tagged-based VLAN is an IEEE 802.1Q specification standard, and t is possible to create a VLAN
across devices from different switch vendors. 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 Tag-based VLAN, and enable or disable GVRP protocol. There are 256 VLAN
groups to provide configure. Enable 802.1Q VLAN, the all ports on the switch belong to default
VLAN, VID is 1. The default VLAN cannot 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 by using the VID of a
VLAN defined on the switch; the switch will automatically add that device to the existing VLAN.
