What are HP-UX VLANs?

Chapter 110

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).

Figure 1-1 VLANs (Virtual LANs)

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.
