Examine the local network topology and determine where subdivision into VLANs is appropriate.
For a basic example of such a topology, refer to Figure 5–1.
Create a numbering scheme for the VIDs, and assign a VID to each VLAN.
A VLAN numbering scheme might already exist on the network. If so, you must create VIDs within the existing VLAN numbering scheme.
On each system, determine which interfaces will be members of a particular VLAN.
Check the connections of the interfaces to the network's switches.
Note the VID of each interface and the switch port where each interface is connected.
Configure each port of the switch with the same VID as the interface to which it is connected.
Refer to the switch manufacturer's documentation for configuration instructions.
