Once you have assigned a priority to the port groups on the Switch, you can then assign this Class to each of the7 levels of 802.1p priorities. Click Apply to set your changes.

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.

Click on the Setup button to open the Setup Forwarding Ports page, as shown below.

Figure 6- 55. Setup Forwarding Ports window

This page allows you to determine which port on a given switch in a switch stack will be allowed to forward packets to other ports on that switch. Configuring traffic segmentation on the AT-9724TS is accomplished in two parts. First, you specify a switch from a switch stack by using the Unit pull-down menu, and then a port from that switch, using the Port pull-down menu.Then specify a second switch from the switch stack, and then you select which ports (or different ports on the same switch,) on that switch that you want to be able to receive packets from the switch and port you specified in the first part.

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 Unit drop-down menu under the Setup Forwarding ports heading allows you to select a switch from a switch stack using that switch’s Unit ID.The Forward Port click boxes allow you to select which of the ports on the selected switch will be able to forward packets.These are the ports that will be allowed to receive packets from the port specified above.

Click Apply to enter the settings into the Switch’s Traffic Segmentation table.
