VLAN Configuration Results
If a packet comes in on port 2, it can go to ports 1, 3, 4, 5, 6, 7, 8, and 25, as those are the only ports
in that VLAN. A Sales person on Port 2 can get to the Internet, send and receive e-mail, but cannot
access the marketing department print server or file archives.
If a Marketing user sends out a broadcast message, the Sales and Accounting departments are not
affected by the message, because it does not go out on their ports. Only the Marketing department
and the IT group will receive the broadcast message.
If an IT user sends out a broadcast message, everyone receives it.
