This feature provides administrators to limit traffic flow from a single port to a group of ports on a single
Switch. This method of segmenting the flow of traffic is similar to using VLANs to limit traffic, but is more
restrictive.

and select Port Map then click Apply to enter the settings into the Switch’s Traffic Segmentation table.
