priority queue. However, the SmartSwitch 2000 will tag outgoing frames with the
full range of eight priority levels, so that upon reception, a device that supports
the entire range of priority queuing will forward the frame appropriately.
You can use SPECTRUM Element Manager to conÞgure the criteria that
determine the priority in which frames will be queued for transmission by your
SmartSwitch 2000. Several different criteria can be used to determine a frameÕs
transmission queue order:
¥ The device and port at which the frame was received.
¥ The destination and/or source MAC address associated with the frame.
¥ A combination of destination and/or source MAC address and the frameÕs
protocol type.
¥ The frameÕs protocol type.
When you conÞgure the transmission queue for a speciÞc frame, an entry is made
in one of three priority tables maintained by the SmartSwitch 2000 device. These
tables are used to determine which transmit queue to use Ñ normal priority or
high priority Ñ when forwarding frames.
¥ The ctPriorityExtPortTable maintains priority entries based on a frameÕs receive
port.
¥ The ctPriorityExtMACTable maintains priority entries based on a frameÕs
MAC-layer information.
¥ The ctPriorityExtPktTypeTable maintains priority entries based on the frameÕs
protocol type.
The following sections discuss how to use the Port Priority ConÞguration
window, the MAC Based Priority ConÞguration window, and the Frame Priority
ConÞguration window to make entries in these transmit priority tables.
Configuring Priority Queuing Based on Receive Port
You can use the Port Priority ConÞguration window, Figure 2-20, to determine
packet queuing based solely upon the port at which the packet was received. This
allows you to ensure that a connected user or LAN segment will have priority
when frames that were received on that port are queued for transmission.
