C-2 Port-Based VLAN
July 2005
• Setting up first VLAN group (IT), VLAN ID = 01, with membership of all ports.
Since VLAN ID 01 has been setup by default, you will have to remove the ports that belong to
all other VLAN group except port 25.
• Ports 7 and 8 are kept for the usage of connecting file server and printer server. Sales and
Marketing departments can share file archives and printing services.
• Port 25 provides Gigabit speed for email server and Internet connection.
The specific ports above have the following functions:
• VLAN 1: Port 15 – Port 18, Port 21 – Port 24, Port 26, for IT department to monitor and
control activities on all other VLANs
• VLAN 2: Port 1 – Port 8, for Sales department, port 7 and 8 connect to file archives and printer
server.
• VLAN 3: Port 7 – Port 14, for Marketing department, port 7 and 8 connect to file archives and
printer server.
• VLAN 4: Port 19 – Port 20, for Accounting department, its work is kept secret from other
departments except IT.
Scenarios:
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 email, 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 will not
be affected by the message, as it will not go out on their ports. Only the Marketing department and
the IT group will get the broadcast message.
If an IT user sends out a broadcast message, everyone will get it.
