• Higher security - If each computer has a separate physical connection to the switch, then
broadcast traffic in each VLAN is never sent to computers in another VLAN.
• Better manageability - You can align network policies more appropriately for users. For example,
you can create different policy route rules for each VLAN (each department in the example
above), and you can set different bandwidth limits for each VLAN. These rules are also
independent of the physical network, so you can change the physical network without changing
policies.
In this example, the new switch handles the following types of traffic:
• Inside VLAN 2.
• Between the router and VLAN 1.
• Between the router and VLAN 2.
• Between the router and VLAN 3.
