Port-Based VLAN Example Configuration
This example demonstrates how the port-based VLANs work to meet your needs.
In this example, you create four new VLANS, you change the port membership for default
VLAN 1, and you assign port members to the four new VLANs:
1. In the Basic VLAN Configuration screen (see “Basic—VLAN Configuration” on page 4-9),
create the following VLANs, each with a defined description:
– A VLAN with VID 1. Enter the following description: IT.
– A VLAN with VID 2. Enter the following description: Sales.
– A VLAN with VID 3. Enter the following description: Market.
– A VLAN with VID 4. Enter the following description: Account.
2. In the VLAN Membership screen (see “Advanced—VLAN Membership” on page 4-12)
specify the VLAN membership as follows:
– For the default VLAN with VID 1 (IT), remove all members except for port 7 and port 8.
(All ports were automatically assigned to the default VLAN.)
– For the VLAN with VID 2 (Sales), specify the following members: port 1, port 2, port 3,
and port 8.
– For the VLAN with VID 3 (Market), specify the following members: port 2, port 3, port 4,
and port 8.
– For the VLAN with VID 4 (Account), specify the following members: port 5, port 6, and
port 8.
In this example, the specified VLANs and ports have the following functions:
• For the VLAN with VID 1, port 7 is used by the IT department to monitor and control
activities on all other VLANs.
• For the VLAN with VID 2, port 1 is used by the Sales department, port 2 connects to the
file archives, and port connects to the printer server.
• For the VLAN with VID 3: por t 4 is used by the Marketing department, port 2 connects to
the file archives, and port connects to the printer server. The file archives and the printer
server are shared with the Sales department,
• For the VLAN with VID 4: port 5 and port 6 are used by the for Accounting department.
Its work is kept secret from other departments except for the IT department.
• For all VLANs: port 8 provides Gigabit speed for an e-mail se rver and an Internet
connection and is accessible to all departments.
