Traffic Segmentation
The traffic segmentation table is used to limit traffic flow from a
single port to other ports on the switch. It cannot be used to
segment traffic between switch units in a stack. For this it
would be appropriate to use VLANs or a filtering method. This
provides an additional tool to direct traffic flow without relying
on the Master CPU.
