Traffic Segmentation Settings
Traffic segmentation is used to limit traffic flow from a single or group of ports, to a group of ports. This method of
segmenting the flow of traffic is similar to using VLANs to limit traffic, but is more restrictive. It provides a method of
directing traffic that does not increase the overhead of the master switch CPU.
