Configuring Egress Scheduling

This procedure explains how to select and configure a scheduling

method for QoS. Scheduling determines the order in which the ports

handle packets in their egress queues. For an explanation of the two

scheduling methods, refer to the AT-S62 Menus Interface User’s Guide.

Scheduling is set at the switch level. You cannot set this at the port level.

To change scheduling, perform the following procedure.

1. From the Home Page, select Configuration.

2. From the Configuration menu, select the Services menu option.

3. Select the Queuing & Scheduling tab.

The Scheduling tab is shown in Figure 51 on page 160.

Note

The Configure CoS Queues to Egress Queues section in the tab is

explained in the previous procedure Mapping CoS Priorities to

Egress Queues on page 159.

4. To select a scheduling method, click either Strict Priority or

Weighted Priority in the Configure Egress Weights section of the

tab. The default is Strict Priority.

Skip the next step if you select Strict Priority. Queue weights do

not apply to Strict Priority scheduling.

5. If you selected Weighted Priority, use the Queue # Weight fields to

specify for each queue the number of packets you want a port to

transmit before it goes to the next queue.

Leaving the default value of 1 for each queue results in all egress

queues being given the same priority.

6. Click Apply.

7. To permanently save the change, click the Save Config menu option.
