About VLANs	The VLAN concept in LAN technology helps minimize broadcast and
	multicast traffic. It also makes end-station moves, adds, and changes
	easier for the network administrator.
	In the CoreBuilder system, VLANs allow you to:
	■ Create independent broadcast domains to optimize network performance
	and create firewalls
	■ Form flexible user groups independent of the users’ physical network
	locations

Types of VLANs You can use several types of VLANs to group users. These types include:

■Port group VLANs

■MAC address group VLANs

■Application-oriented VLANs

■Protocol-sensitive VLANs
