Chapter 16. VLAN Configuration
VLAN Introduction 16.1
Virtual LAN (VLAN) refers to a group of logically networked devices on one or more LANs that are configured
so that they can communicate as if they were attached to the same wire, when in fact they are located on a
number of different LAN segments. In 1999 IEEE established IEEE 802.1Q Protocol Standard Draft used to
standardize VLAN realization project. Because VLANs are based on logical instead of physical connections, it
is very flexible for user/host management, bandwidth allocation and resource optimization.
There are the following types of Virtual LANs:
Port-Based VLAN: each physical switch port is configured with an access list specifying membership in a
set of VLANs.
802.1Q trunk mode is supported on the interface.
Access mode interface is supported.
Port-Based Vlan is to ascribe port to one subset of vlan that the switch supports. If this vlan subset has
only one vlan, then this port is access port. If this vlan subset has multiple vlan, then this port is trunk port.
There is one default vlan among the multiple vlan, and the vlan id is the port vlan id (PVID).
Vlan-allowed range is supported on the interface.
Vlan-allowed parameter is used to control vlan range that the port belongs. Vlan-untagged parameter is
used to configure port to send packets without vlan tag to the corresponding vlan.

16.3.1 Adding/Deleting VLAN
A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that
communicate as if they were attached to the same wire, regardless of their physical location. A VLAN has the
same attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not
located on the same LAN segment. A VLAN may have multiple ports and all unicast, multicast and broadcast
message can only be forwarded from the same VLAN to the terminal. Each VLAN is a logistical network. If the
data wants to reach another VLAN, it must be forwarded by router or bridge.
