Section 8.5
Managing VLANs
A Virtual Local Area Network (VLAN) is a group of devices on one or more LAN segments that communicate as if
they were attached to the same physical LAN segment. VLANs are extremely flexible because they are based on
logical connections, rather than physical connections.
When VLANs are introduced, all traffic in the network must belong to one VLAN or another. Traffic on one VLAN
cannot pass to another, except through an inter-network router or Layer 3 switch.
VLANs are created in three ways:
•
Explicitly
Static VLANs can be created in the switch. For more information about static VLANs, refer to Section 8.5.5,
“Managing Static VLANs” .
