A vlan can span multiple interconnected switches.
<h3>
What is a vlan?</h3>
A virtual LAN (VLAN) is a logical overlay network that groups together a subset of devices that share a physical LAN, isolating the traffic for each group.
A LAN is a group of computers or other devices in the same place -- e.g., the same building or campus -- that share the same physical network.
Each virtual switch, or VLAN, is simply a number assigned to each switch port.
For example, the two switch ports in the red mini-switch might be assigned to VLAN #10 . The two ports in the orange mini-switch might be assigned to VLAN #20 .
VLANs can be used for different groups of users, departments, functions, etc., without needing to be in the same geographical area.
VLANs can help reduce IT cost, improve network security and performance, provide easier management, as well as ensuring network flexibility.
