Huawei quidway s7700 - Configuring Complex Traffic Classification; Configuring a Traffic Policing Action on the

No. Data
1 Name of the traffic classifier and related parameters
2 Name of the traffic behavior and CAR parameters: CIR, (optional) CBS, (optional)
PIR, (optional) PBS, (optional) color, (optional) coloring mode, and (optional) CoS
3 Name of the traffic policy, and object and inbound or outbound direction to which
traffic policing based on a traffic classifier is applied
2.3.2 Configuring Complex Traffic Classification
The S7700 can classify traffic according to the ACL, Layer 2 information in packets, and Layer
3 information in packets.
Select proper traffic classification rules and configure complex traffic classification as required.
For details, see 1.4.2 Configuring Complex Traffic Classification.
2.3.3 Configuring a Traffic Policing Action on the
You can configure traffic policing actions, set the CIR, PIR, CBS, and PBS values, and configure
actions for packets with different PHBs and colors.
Context
Level-2 CAR is supported by the S7700. After the system applies the CAR to the service flows
matching a traffic classifier in a traffic policy, it aggregates all the service flows matching the
traffic classifier bound to the aggregate CAR action in the same traffic policy and applies the
CAR to the flows. This is also called hierarchical traffic policing.
Hierarchical traffic policing implements traffic statistics multiplexing and service control. For
example, hierarchical traffic policing limits the traffic of services of level-1 and level-2 users or
traffic of level-1 user groups and level-2 users.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
traffic behavior behavior-name
A traffic behavior is created and the traffic behavior view is displayed.
Step 3 Run:
car cir cir-value [ pir pir-value ] [ cbs cbs-value pbs pbs-value ][ mode { color-
blind | color-aware } ] [ green { discard | pass [ service-class class color
color ] } ] [ yellow { discard | pass [ service-class class color color ] } ]
[ red { discard | pass [ service-class class color color ] } ]
*
A CAR action is configured.
