VLAN
This chapter provides an overview of VLAN and explains how to use it with the SuperStack II Switch 1000.
VLAN Overview
VLAN stands for virtual local area network.VLAN is a network configura- tion tool that allows you to “group” together specific ports on the same switch, designating them as their own virtual network segments.
With the SuperStack II Switch 1000 Personality Module, the use of VLAN lets you:
❏Create up to 16 separate user groups
❏Limit broadcast and multicast traffic
❏Increase security (by specifying which segments can communicate with each other)
❏Allocate network resources (such as servers)
❏Designate specific application groups
You can create up to 16 separate VLANs on the SuperStack II Switch 1000 by assigning each port on the switch to a VLAN number. By group- ing certain ports together, you effectively “cut” the switch into com- pletely independent segments.
For example, you can designate ports 2, 6, and 8 to be on VLAN1 and ports 1, 10, and 12 to be on VLAN2. As a result, each group of ports will have its own workgroup and resources within its domain. You can cre- ate and reconfigure these workgroups, reallocate resources as required, and gather statistics at the VLAN group and port levels.
