• In a port, one H2 node and three H1 nodes are supported. The H1 node holds 8 unicast queues for data traffic, 8 unicast queues for control traffic, and 8 multicast queues for data traffic. • The H1 nodes mapped to data traffic are scheduled with DWRR and weight of 50 each. The H1 node mapped to control traffic is scheduled with strict priority. • The weights corresponding to each traffic class are applied at queue levels for both unicast and multicast queues. • The bandwidth distribution might go to a minimum of 50, based on the traffic flow in a port. This is determined by the weight of a particular traffic class and traffic type. • The bandwidth sharing based on ETS happens only between same type of queues. • You can enable strict priority queuing only for the same type of traffic.
