7.3 VLAN ( Virtual LAN )
A VLAN ( Virtual LAN ) is a group of switching ports designated by the switch as belonging to the same broadcast
domain. This feature allows the workgroup to be defined on the basis of their logical location instead of their
physical location, and this does not require recalling.
If a broadcast packet is received from a port, it will forward this broadcast packet only to those ports belonging to
the same VLAN. VLAN classification of every packet is done in the following way: If the packet is tagged with
non-zero VLAN-id field then this is used as the VLAN id. Otherwise the default VLAN id of the input port is used.
You can assign a single switch port to two or more VLANs. The factory default VLAN is that all ports belong to
the same VLAN group 1. VLAN also enable you to configure tag-based VLANs to help isolate broadcast traffic
and increase security. Creating VLANs increases network flexibility by allowing you to reassign devices to
accommodate network moves, additions, and changes, eliminating the need to change physical cabling.
The switch supports up to 4095 tag-based 802.1Q-compatible virtual LANs (VLANs).
