Configuration

Figure 2-19 Typical VLAN Application Topology

The existing LAN is required to be partitioned to 3 VLANs due to security and

application requirements. The three VLANs are VLAN2, VLAN100 and VLAN200. Those

three VLANs are cross two different location A and B. One switch is placed in each site,

and cross-location requirement can be met if VLAN traffic can be transferred between the

two switches.

Connect the Trunk ports of both switches for a Trunk link to convey the cross-switch

VLAN traffic; connect all network devices to the other ports of corresponding VLANs.

In this example, port 1 and port 12 are spared and can be used for management port

or for other purposes.

The configuration steps are listed below:

Switch A:

Switch(config)#vlan 2

Switch(Config-Vlan2)#switchport interface ethernet 1/0/2-4

Switch (Config-Vlan2)#exit

Switch (config)#vlan 100
