Chapter 9. VLANs
© Copyright Lenovo 2016
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 154
"VLAN Tagging/Trunk Mode" on page 156
"VLAN Topologies and Design Considerations" on page 161
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.
"Protocol‐Based VLANs" on page 166
"Private VLANs" on page 169
Note: VLANs can be configured from the Command Line Interface (see "VLAN
Configuration" as well as "Port Configuration" in the Command Reference).
