Configuring QoS
Policy
The procedure for configuring QoS policy is as follows:
1 Define a class and define a group of traffic classification rules in class view.
2 Define a traffic behavior and define a group of QoS actions in traffic behavior
view.
3 Define a policy and specify a traffic behavior corresponding to the class in policy
view.
4 Apply the QoS policy in Ethernet port view/port group view.
