The Switch's default settings draw down seven hardware classes of service in order, from the highest priority class (Class 6) to the lowest priority class (Class 0). Starting with the highest priority class (Class 6), the highest priority class will transmit all of the packets and empty its buffer before allowing the next lower priority class to transmit its packets. The next highest priority class will empty before proceeding to the next class and so on. Lower priority classes are allowed to transmit only if the higher priority classes in the buffer are completely emptied. Packets in the higher priority classes are always emptied before any in the lower priority classes. The default settings for QoS scheduling employ this strict priority scheme to empty priority classes. The config scheduling command can be used to specify the weighted round-robin (WRR) rotation by which these seven hardware priority classes of service are reduced. To use a weighted round-robin (WRR) scheme, the max_packets parameters must not have a value of zero (0). (See Combination Queue below.) The max_packet parameter allows you to specify the maximum number of packets a given priority class can transmit per weighted round-robin (WRR) scheduling cycle. This provides for a controllable CoS behavior while allowing for other classes to empty as well. A value between 0 and 15 packets can be specified per priority queue. 106
