Chapter 9. VLANs

© Copyright Lenovo 2015
This chapter describes network design and topology considerations for using
Virtual Local Area Networks (VLANs). VLANs are commonly 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 113
 "VLAN Tagging/Trunk Mode" on page 117
 "VLAN Topologies and Design Considerations" on page 122
 "Protocol‐Based VLANs" on page 125
"Private VLANs" on page 128

Note: Basic VLANs can be configured during initial switch configuration (see
"Using the Setup Utility" in the Lenovo N/OS 8.2 Command Reference). More
comprehensive VLAN configuration can be done from the Command Line Interface
(see "VLAN Configuration" as well as "Port Configuration" in the Lenovo N/OS 8.2
Command Reference).
