VLAN
VLAN		In this application Vanguard 342 is directly connected to a VLAN switch. Switches
		are data link-layer devices that, like bridges, enable multiple physical LAN segments
		to be interconnected into a single larger network. The WAN traffic consists of data
		destined to remote resources. There should be virtually no traffic between local
		devices.
