1.1 VLAN Overview
Virtual Local Area Network (VLAN) groups the devices of a LAN logically but not
physically into segments to implement the virtual workgroups. IEEE issued the IEEE
802.1Q in 1999, which was intended to standardize VLAN implementation solutions.
Through VLAN technology, network managers can logically divide the physical LAN
into different broadcast domains. Every VLAN contains a group of workstations with the
same demands. The workstations of a VLAN do not have to belong to the same
physical LAN segment.
With VLAN technology, the broadcast and unicast traffic within a VLAN will not be
forwarded to other VLANs, therefore, it is very helpful in controlling network traffic,
saving device investment, simplifying network management and improving security.
VLANs are divided into four categories:
Port-based VLAN
MAC-based VLAN
Network layer-based VLAN
Policy-based VLAN
S6500 Series Switches support the port-based VLAN and the network layer-based
VLAN. The network layer-based VLANs are divided by protocols such as IP and IPX, so
they are called protocol-based VLANs.
Dividing VLANs based on port is the simplest and most efficient. It defines VLAN
members according to switch ports.
Protocol-based VLAN is divided according to protocol types. Though this method is
based on protocols, it is not related to routes and has nothing to do with routing at the
network layer.
1.2 VLAN Common Configuration
VLAN common configurations refer to those configurations suitable for both the
port-based VLAN and the protocol-based VLAN.
VLAN configuration includes:
Create/Delete a VLAN
Set Ethernet Port or VLAN Broadcast Suppression
