Chapter 3.VLAN Configuration
VLAN is a very important technology in a switch, it’s used often in real networks and is a critical
method to partition the whole network topology to multiple subnetworks. VLAN means Virtual
Local Area Network, it’s a logical network by organizing together multiple devices, no matter
where they are physically in the network. Though logically, each vlan has the same functionality
and characteristics of traditional physical networks. Each vlan represents a broadcast domain,
broadcast packets can only transmit inside the vlan, not allowed to span multiple vlans.
Communication spanning multiple vlans needs to accomplished by layer 3 transmission.
The iSpirit 3026 switch supports VLAN and Private VLAN, so usually VLAN is also called normal
VLAN. This chapter introduces normal VLAN configuration, for private VLAN, please refer to the
corresponding chapter.
