7 Appendix- VLAN Example
LAN switches can segment networks into logically defined virtual work-
groups.This logical segmentation is commonly referred as a virtual LAN
(VLAN). This logical segmentation of devices provides better LAN adminis-
tration, security, and management of broadcast activity over the network. Vir-
tual LANs have become an integral feature of switched LAN solutions.
The VLAN example below demonstrates a simple VLAN
configuration.
If a single port is a member of VLANs 2, 3 and 4, the port expects to see traffic
tagged with either VLAN 2,3 or 4.
The PVID (Port Virtual Identification) could be something entirely different,
for example '12' and things would still work fine, just so incoming traffic was
tagged.
Example:
Project A = (VLAN2, ports 1,2)
Project B = (VLAN3, ports 3,4)
Project C = (VLAN4, ports 5,6)
Project P = (VLAN 9, port 7)
