Recommended QoS policy configuration procedure

Remarks
1. Configuring a
class.
Optional.
This task creates a class and configures classification rules for the class.
The system-defined classes include default-class, ef, af1, af2, af3, af4, ip-prec0,
ip-prec1, ip-prec2, ip-prec3, ip-prec4, ip-prec5, ip-prec6, and ip-prec7.
You cannot modify or delete a system-defined class. Support for the system-defined
classes depends on the device model. For more information, see the traffic classifier
command in Network Management Command Reference.
2. Configuring a
traffic behavior.
Optional.
This task creates a traffic behavior and configures actions for the traffic behavior.
By default, the system-defined traffic behaviors include ef, af, be, be-flow-based,
and so on.
You cannot modify or delete a system-defined traffic behavior.Support for the
system-defined traffic behaviors depends on the device model. For more
information, see the traffic behavior command in Network Management Command
Reference.
3. Configuring a
policy.
Optional.
This task creates a QoS policy and configures class-behavior associations for the
QoS policy.
The system-defined policy is policy default, whose contents are as follows:
• System-defined class ef is associated with system-defined traffic behavior ef.
• System-defined classes af1 through af4 are associated with system-defined traffic
behavior af.
• System-defined class default-class is associated with system-defined traffic
behavior be.
You cannot modify or delete the system-defined policy.
A class can be associated with only one traffic behavior in a QoS policy. If a class
is associated with multiple traffic behaviors, the last associated one takes
effect.Support for the system-defined policy depends on the device model. For more
information, see the classifier behavior command in Network Management
Command Reference.
4. Applying the
policy to an
interface.
Required.
Apply the QoS policy to the specified interface.
5. Configuring port
bandwidth limit.
When CBQ is configured on an interface, you can set the maximum available
interface bandwidth, which can be used for bandwidth check when CBQ enqueues
packets.
Configuring a class
To configure a class, create it first, and then configure classification rules for it.
Creating a class
1. Select Firewall > QoS > Classifier from the navigation tree.
