Fig 9-2 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.
Configuration
Item
Configuration description
VLAN2 Site A and site B switch port 2 -8.
VLAN100 Site A and site B switch port 9 -15.
VLAN200 Site A and site B switch port 16 -22.
Trunk port Site A and site B switch port 23.
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 24 is spared and can be used for management port or
for other purposes.
