Configuring CoS

To configure CoS for a port, perform the following procedure:

1. From the Main Menu, type 1 to select Port Menu.

The Port Menu is shown in Figure 26 on page 102.

2. From the Port Menu, type 1 to select Port Configuration. The

following prompt is displayed:

Enter port-list:

3. Enter the port you want to configure. For information on entering

ports, refer to Specifying Ports on page 34.

The Port Configuration menu for the selected port(s) is displayed.
Option 3 control CoS.

4. Type 3 to toggle Option 3 - Override Priority through the possible

settings. The settings are:

❑ No Override - All ingress tagged frames with a priority of 0 to 3 are

sent to the low priority egress queue and tagged frames with a
priority of 4 to 7 are sent to the high priority egress queue. Ingress
untagged frames are sent to the low priority queue.

❑ Low Priority - All ingress tagged and untagged frames are

directed to the low priority egress queue.

❑ High Priority - All ingress tagged and untagged frames received

on a port are directed to the high priority egress queue.

5. After making changes, type R until you return to the Main Menu. Then

type S to select Save Configuration Changes.

Note

The tagged information in a frame is not changed as the frame
traverses the switch. A tagged frame leaves a switch with the same
priority level that it had when it entered, regardless of the priority
queue that handled the frame.

Note

To view the priority queue assignment for a port, use the Port Status
selection in the Port Menu.
