What is a VLAN?
Rating:
A VLAN is a broadcast domain created by a switch. Each broadcast domain connected to the interfaces of the switch is known as a separate VLAN. A VLAN should be configured when a LAN has lots of traffic or more than 200 devices. It is also required when groups of users need more security or when a group of users have the same type of work and need to be on the same broadcast domain.
