GS748T Software User Manual

Setting up third VLAN group (Marketing), VLAN ID = 03, with membership of ports 7~14, 25.

Setting up fourth VLAN group (Accounting), VLAN ID = 04, with membership of ports 19~20, 25.

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 groups except port 25.

Ports 7 and 8 are kept for connected file server and printer server use. Sales and Marketing departments can share file archives and printing services.

Port 25 provides Gigabit speed for e-mail 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.

Results of this Configuration

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.
