CHAPTER 6
VLANs
This chapter describes network design and topology considerations for using Virtual Local Area
Networks (VLANs). VLANs commonly are used to split up groups of network users into
manageable broadcast domains, to create logical segmentation of workgroups, and to enforce
security policies among logical segments. The following topics are discussed in this chapter:
“VLANs and Port VLAN ID Numbers” on page 88
“VLAN Tagging” on page 90
“VLAN Topologies and Design Considerations” on page 94
This section discusses how you can connect users and segments to a host that supports many
logical segments or subnets by using the flexibility of the multiple VLAN system.
“Private VLANs” on page 98
Note – VLANs can be configured from the Command Line Interface (see “VLAN Configuration”
as well as “Port Configuration” in the Command Reference).
