•Types of VLANs (Section 12.2)

•Benefits and Restrictions (Section 12.3) of VLANs

•VLAN Terms (Section 12.4)

•VLAN Operation (Section 12.5)

•Configuration Process (Section 12.6)

•VLAN Switch Operation (Section 12.7)

•VLAN Configuration (Section 12.8)

•Summary of VLAN Local Management (Section 12.9)

•Quick VLAN Walkthrough (Section 12.10) setting up a Static VLAN using Local Management

•Examples (Section 12.11) showing how VLAN-aware switches can be configured based on a given problem
