7 VLAN
VLAN is formulated not restricted to physical locations, which means the hosts in a
same VLAN can be placed at will. As shown below, each VLAN, as a broadcast domain,
divides a physical LAN into logical LANs. Hosts can exchange messages by means of
traditional communication. For the hosts in different VLANs, the device such as router
or L3 switch is a must.
VLAN is superior to the traditional Ethernet in terms of:
⚫ Broadcast domain coverage: the broadcast message in a LAN is limited in a VLAN
to save the bandwidth and handle the network-related issues more efficiently.
⚫ LAN security: VLAN hosts fail to communicate with each other since the messages
are separated by the broadcast domain in the data link layer. They need a router or
a Layer 3 switch for Layer 3 forwarding.
⚫ Flexibility of creating a virtual working team: VLAN can create a virtual working
team beyond the control of physical network. Users have access to the network
without changing the configuration if their physical locations are moving within the
scope. This management switch is compatible with VLAN types based on 802.1Q,
protocols, MAC, and ports. For default configuration, 802.1Q VLAN mode should
be adopted. Port VLAN is divided subject to a switch’s interface No. Network
administrator gives each switch interface a different PVID, namely a port default
VLAN. If a data frame without a VLAN tag flows into a switch interface with a PVID,
it will be marked with the same PVID, or it will get rid of an additional tag even
though the interface has a PVID.
⚫ The solution to a VLAN frame depends on the interface type, which eases member
definition but re-configures VLAN in case of member mobility.
