Chapter 9 VLAN Configuration
9.1 Introduction to VLAN
VLAN (Virtual Local Area Network) is a technology that divides the logical addresses of
devices within the network to separate network segments based on functions, applications or
management requirements. This way, virtual workgroups can be formed regardless of the physical
location of the devices. IEEE 802.1Q protocol was announced to direct the standardized VLAN
implementation. ES4710BD VLAN implementation follows IEEE 802.1Q.
VLAN technology can partition a big LAN into many separate broadcast domains dynamically
to meet demands.
Fig 9-1 A VLAN network defined logically
Each broadcast domain is a VLAN. VLANs have the same properties as the physical LANs,
except VLAN are a logically partitioned rather than physical. Therefore, the partition of VLANs can
be performed regardless of physical locations. Furthermore, broadcast, multicast and unicast traffic
within a VLAN are separated from other VLANs.
With the afore-mentioned features, VLAN technology provides us with the following
