What are HP-UX VLANs?

A Virtual LAN (VLAN) is a logical or virtual network segment that can span multiple physical network segments. Using VLANs, you can group switched-network end-stations by:

•department, such as engineering and manufacturing,

•type of user, such as power users or those with special needs,

•application, or

•project

instead of physical location (Figure 1-1).

VLANs isolate broadcast and multicast traffic by determining which destinations should receive that traffic, thereby making better use of switch and end-station resources. With VLANs, broadcasts and multicasts go only to the intended nodes in the virtual LAN.
