Planning Your Internal Network - LevelOne WHG-311 User Manual

5.6.1. Planning Your Internal Network


Simple network environment
For most simple internal network, such as there are just only two subnets. Using Port-Based model is an easy
and better way. In Port-Based mode, each LAN port can only serve traffic from one Service Zone. An example
of network application diagram is shown as below: one Service Zone for Employees and one for Guests.
The switches deployed under WHG Controller in Port-Based mode must be Layer 2 switches only.

Multi subnet network environment
On the other hand, if the internal network is a Multi subnets network environment, Tag-Based model will satisfy to
your conditions. In Tag-Based mode, each LAN port will serve traffics from different Service Zones; a VLAN switch
or VLAN AP is required to take care of the VLAN tags carried within the message frames.
An example of network application diagram is shown as below: more than two Service Zones for different
departments.
The switch deployed under WHG Controller in Tag-Based mode must be a VLAN switch only.
