4.4.7 VLAN configuration

A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast

domain. It allows you to isolate network traffic so only members of the same

VLAN receive traffic from other VLAN members. Creating a VLAN from a

switch is logically equivalent to 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

protocol-based VLANs. In the default configuration, VLAN support is

enabled and all ports on the switch belong to the default VLAN, whose

VLAN ID (VID) is 1.

Note: The default VLAN cannot be deleted.

Port-based VLANs (IEEE 802.1Q VLAN)

This feature is an IEEE 802.1Q specification standard. Therefore, it 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.
