Step Command Remarks
3. Configure the CAR action.
qos car { inbound | outbound } any cir
committed-information-rate [ cbs
committed-burst-size [ ebs
excess-burst-size ] ] [ pir
peak-information-rate ]
The conforming traffic is
permitted to pass through, and
the exceeding traffic is dropped.
4. Return to system view. quit N/A
5. Activate the user profile. user-profile profile-name enable Inactive by default
NOTE:
If a user profile is activated, you cannot modify or remove the CAR policy applied to it. For more
information about user profiles, see Security Configuration Guide.
Configuring the line rate
NOTE:
Support of the H3C WX series access controllers for features may vary by device model. For the feature
matrixes, see
About the WX Series Access Controllers Configuration Guides.
The line rate of a physical interface specifies the maximum rate of incoming packets or outgoing packets.
To configure the line rate:
Step Command Remarks
1. Enter system view system-view N/A
2. Enter interface view
or port group view
• Enter interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual port-group-name
Use either command.
Settings in interface view take effect
on the current interface. Settings in
port group view take effect on all
ports in the port group.
3. Configure the line
rate for the interface
or port group
qos lr outbound cir
committed-information-rate [ cbs
committed-burst-size ]
N/A
NOTE:
•
To enable line rate to function properly, make sure the committed-burst-size argument in the qos lr
outbound cir command is greater than or equal to 1875 or committed-information-rate×100/16,
whichever is greater. Otherwise, the physical interface may operate improperly.
• To ensure effective burst handling, set the ratio of the CBS to CIR greater than 100:16 when configuring
line rate or a traffic policing behavior.
• When line rate is used in conjunction with queuing, set the queue length to 1024 to make sure that the
expected queue scheduling effect can be achieved.
