For a network port, the scheduling behavior is similar, except that per SAP scheduler is not present in the hierarchy. Instead, per port scheduler distributes the available port bandwidth to all the queues configured on the port in two passes with the behavior being similar to the per SAP scheduler (as mentioned above). Additionally, all the traffic sent out on the network port uses a set of 8 queues which are mapped to the 8 forwarding classes. This is shown in the following figure.
