qos car

qos car

Function

The qos car command creates a QoS CAR profile and set QoS CAR parameters.

The undo qos car command deletes a QoS CAR profile.

By default, no QoS CAR profile is created in the system.

Format

qos car car-name cir cir-value [ cbs cbs-value [ pbs pbs-value ] | pir pir-value [ cbs cbs-value pbs pbs-value ] ]

undo qos car car-name

Parameters

Parameter

Description

Value

car-name

Specifies the name of a QoS CAR profile.

The value is a string of 1 to 31 characters.

cir cir-value

Specifies the committed information rate (CIR), which is the average rate of traffic that can pass through.

The value is an integer that ranges from 64 to 4294967295, in kbit/s.

pir pir-value

Specifies the peak information rate (PIR), which is the maximum rate of traffic that can pass through.

The value is an integer that ranges from 64 to 4294967295, in kbit/s.

The PIR value must be larger than or equal to the CIR value.

cbs cbs-value

Specifies the committed burst size (CBS), which is the average volume of burst traffic that can pass through.

The value is an integer that ranges from 1500 to 4294967295, in bytes.

By default:
  • If the PIR value is not set or the PIR and CIR values are the same, the CBS value is 188 times the CIR value. If the value 188 times the CIR exceeds the maximum value (4294967295) of the CBS, 4294967295 is used.
  • If the PIR is set and the PIR and CIR are different, the CBS is 125 times the CIR. If the value 125 times the CIR exceeds the maximum value (4294967295) of the CBS, 4294967295 is used.

pbs pbs-value

Specifies the peak burst size (PBS), which is the maximum volume of burst traffic that can pass through.

The value is an integer that ranges from 1500 to 4294967295, in bytes.

By default:
  • If the PIR is set to the same as the CIR, the PBS is 313 times the CIR. If the value 313 times the CIR exceeds the maximum value (4294967295) of the PBS, 4294967295 is used.
  • If the PIR is set and the PIR and CIR are different, the PBS is 125 times the PIR. If the value 125 times the PIR exceeds the maximum value (4294967295) of the PBS, 4294967295 is used.

Usage Guidelines

To monitor the volume of the traffic that enters a network and limit incoming or outgoing traffic within a proper range, you need to configure a traffic policy. QoS CAR technology implements traffic policing on user services, such as voice or video services, by creating a QoS CAR profile that defines QoS CAR parameters and applying it to the inbound direction on an interface or in a VLAN.

Example

# Create a QoS CAR profile named qoscar1, and set the CIR value to 10000 kbit/s and the CBS value to 10240 bytes.
