Configuring Port Scheduler Policies
The port-scheduler-policy command creates a port scheduler template which may be assigned to
an egress port. Only one port scheduler policy is allowed per port. There is a “default” port-
scheduler policy (which services the queues of the port in a Strict order) associated with each port.
To change the behavior, users can associate the port with another port-scheduler policy. The policy
contains mode commands to set the mode of scheduling (RR, Strict, WRR, WDRR) and queue
commands to set the weight of the queue (only 8 queues per port and queue settings only for
WRR/WDRR modes). In WRR/WDRR, a strict option treats that particular queue as a strict
queue, this leads to a hybrid mode of scheduling (WRR+Strict, WDRR+Strict).
