VLAN policies determine how VLANs function across your network environment.
A virtual local area network (VLAN) is a group of hosts with a common set of requirements, which communicate as if they were attached to the same broadcast domain, regardless of their physical location. A VLAN has the same attributes as a physical local area network (LAN), but it allows for end stations to be grouped together even if not on the same network switch.
The scope of VLAN policies can be distributed port groups and ports, and uplink port groups and ports.
