Configuring Qos; Non-Policy Approach; Policy Approach - HP A6600 Configuration Manual

Configuring QoS

The following approaches are available for configuring QoS:
Some features support both approaches, but some support only one.

Non-policy approach

In non-policy approach, configure QoS service parameters directly without using a QoS policy. For example,
use the line rate feature to set a rate limit on an interface without using a QoS policy.

Policy approach

In policy approach, you configure QoS service parameters by using QoS policies. A QoS policy defines the
shaping, policing, or other QoS actions to take on different classes of traffic. It is a set of class-behavior
associations.
A class is a set of match criteria for identifying traffic. It uses the AND or OR operator:
If the operator is AND, a packet must match all the criteria to match the class.

If the operator is OR, a packet matches the class if it matches any of the criteria in the class.

A traffic behavior defines a set of QoS actions to take on packets, such as priority marking and redirect.
By associating a traffic behavior with a class in a QoS policy, you apply the specific set of QoS actions to the
class of traffic.
