This appendix contains:

■

A description of Virtual LAN (VLAN) concepts and their operational aspects 
in the CoreBuilder

™

 6000 system

■

Examples of VLAN configurations

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

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
