Configuring Priority Queuing Based on MAC-layer Information
You can use the MAC Based Priority Configuration window, Figure2-19, 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.

NOTE
Since the SmartSwitch 2000 device has 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 f orwarde d
when it is received by another device.
Click Add to enter a
MAC Address to which
you want to assign a
higher priority
transmission queue.
Select whether you want
the address type to be
destination, source, or
either type.
Determine whether to apply the
priority to all frames with the given
address and SA/DA type, or only
to frames of a specific type.
Finally, select a priority level,
and click Apply.
