VLAN
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast
domain, which allows you to isolate 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 logically equivalent of reconnecting a group of network devices to
another Layer 2 switch. However, all the network devices are still plugged into the
same switch physically.
The switch supports port-based and 802.1Q (tagged-based) VLAN. The default
configuration of VLAN operation mode is at “
802.1Q
”.
5.1.8.1
VLAN Setting - IEEE 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 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 configure. Enable 802.1Q VLAN, the all ports on the
switch belong to default VLAN, VID is 1. The default VLAN cannot be deleted.
