Traffic Segmentation
Traffic segmentation is used to limit traffic flow from a single port to a group of ports on either a single Switch (in standalone mode) or a group of ports on
another switch in a switch stack.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.
In the Configuration folder open the
QoS folder and click Traffic Segmentation,to view the screen shown below.

Clicking the
Apply button will enter the combination of transmitting port and allowed receiving ports into the Switch’s Traffic Segmentation table.
The
Unit drop-down menu at the top of the page allows you to select a switch from a switch stack using that switch’s Unit ID.The Port drop-down menu
allows you to select a port from that switch.This is the port that will be transmitting packets.
The
