Enterasys Networks 6000, Matrix E7 Configuring Priority Queuing Based on MAC-layer Information

The Device View

To assign a transmit priority to a port:

1.Click to highlight the port interface of interest in the Port # column. Each interface is identified by its MIBII IfIndex.

2.Click on the Transmit Priority drop-down list box, and scroll to select the desired priority level (Normal–7) for forwarding packets received on the selected port.

NOTE

Since the SmartSwitch 6000 and Matrix E7 modules have two transmit queues, a priority of Normal will cause packets received on that port to be forwarded through the lower priority queue, and any priority of 1 through 7 will cause the packets to be forwarded through the higher priority queue. However, other tag-aware switches may use the full range of eight priority queues — so the priority that you assign may have bearing on how the frame is forwarded when it is received by another device.

3.Click the Apply button. The defined priority will appear next to the port in the Transmit Priority column.

Configuring Priority Queuing Based on MAC-layer Information

You can use the MAC Based Priority Configuration window, Figure 2-21, to determine packet queuing based upon the packet’s Source and/or

Destination MAC address, as well as the packet’s frame Type. These priority entries, based on the frame’s MAC-layer information, are maintained in the ctPriorityExtMACTable. You can create up to 1024 priority entries for queuing frames based upon on MAC-layer information.
