QoS Setup
A total of 4 prioritized queues are provided for Ethernet packets, denoted as Queue0 (lowest priority), Queue1,
Queue2 and Queue3 (highest priority). You may assign the different packet dropping ratio and service weights for
different queues. Refer to Chapter “ADVANCED FEATURES” for more CC100
QoS mechanism details.
For example, according to the following setting diagram we classify TCP/UDP packet with port ‘1234’ or ‘80’
(decimal) as the highest priority packet goes to Queue3, port ‘23’ goes to Queue2 and port ‘161’ goes to Queue1.
Queue3 will not discard any packet (Drop Ratio 0%), and packets in Queue3 are transmitted 4 times faster than
packets in Queue0 according to their ‘Service Weight’. Packets in Queue0/Queue1/Queue2 will be discarded
according to their ‘Drop Ratio’ in case of any congestion.
