Figure 43: Physical topology of the addition of new hosts with VLAN-aware equipment
Besides the physical installation, VLAN mechanism will make the hosts see each
other as if they were at the same physical LAN, as shown in the next figure. Thus,
there is no more dependency on the equipment connections. With VLAN, it is possible

Traffic segregation through Virtual LAN (VLAN) is standardized by IEEE 802.1Q
document. The standard added 4-bytes in the Ethernet frame, where information
