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.
