·     remark-prec-pass new-precedence: Re-marks the packet with a new IP precedence and permits the packet to pass through. The new-precedence argument is in the range of 0 to 7.

Usage guidelines

To use two rates for traffic policing, configure the qos car command with the pir peak-information-rate option. To use one rate for traffic policing, configure the qos car command without the pir peak-information-rate option.

You can configure multiple qos car commands on an interface to define multiple CAR policies. These CAR policies are executed in their configuration order.

Examples

# Perform CAR for all packets in the outbound direction of GigabitEthernet 1/0/1. The CAR parameters are as follows:

·     CIR is 200 kbps.

·     CBS is 5120 bytes.

·     EBS is 0.

·     Conforming packets are transmitted.

·     Excess packets are set with an IP precedence of 0 and transmitted.

network-admin

Parameters

carl-index: Specifies a CAR list by its number in the range of 1 to 199.

dscp dscp-list: Specifies a list of DSCP values. A DSCP value can be a number from 0 to 63 or any of the following keywords af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs1, cs2, cs3, cs4, cs5, cs6, cs7, default, or ef. You can configure up to eight DSCP values in one command line. If the same DSCP value is specified multiple times, the system considers the values to be one value. If a packet matches one of the defined DSCP values, it matches the if-match clause.

mac mac-address: Specifies a MAC address in hexadecimal format.

mpls-exp mpls-exp-value: Specifies an MPLS EXP value in the range of 0 to 7. You can configure up to eight MPLS EXP values in one command line. If the same MPLS EXP value is specified multiple times, the system considers the values to be one value. If a packet matches one of the defined MPLS EXP values, it matches the if-match clause.

precedence precedence: Specifies a precedence value in the range of 0 to 7. You can configure up to eight IP precedence values in one command line. If the same IP precedence value is specified multiple times, the system considers the values to be one value. If a packet matches one of the defined IP precedence values, it matches the if-match clause.

destination-ip-address: Configures a destination IP address-based CAR list.

source-ip-address: Configures a source IP address-based CAR list.

range start-ip-address to end-ip-address: Specifies an IP address range by the start address and end address. The value for end-ip-address must be greater than the value for start-ip-address. The maximum number of IP addresses that an IP address range can accommodate is 1024.

subnet ip-address mask-length: Specifies a subnet by the IP subnet address and IP subnet address mask length. The value range for mask-length is 22 to 31.

per-address: Performs per-IP address rate limiting within the network segment. When this keyword is specified, the CIR is dedicated bandwidth for each IP address and is not shared by any other IP address. If you do not specify this keyword, the following events occur:

·     Rate limiting is performed for the entire network segment.

·     All of the CIR is allocated among all IP addresses in proportion to the traffic load of each IP address.

shared-bandwidth: Specifies that traffic of all IP addresses within the network segment shares the remaining bandwidth (the CIR). If you specify this keyword, all of the CIR is allocated evenly among all IP addresses with traffic load.

Usage guidelines

You can create a CAR list based on IP precedence, MAC address, MPLS EXP, DSCP, or IP network segment.

If you execute this command multiple times for the same CAR list, the most recent configuration takes effect. If you execute this command multiple times for different CAR lists, multiple CAR lists are created.

To perform rate limiting for a single IP address, use the qos car acl command in interface view.

Examples

# Apply CAR list 1 to the outbound direction of GigabitEthernet 1/0/1 to meet the following requirements:

·     The rate of each host on the subnet 1.1.1.0/24 is limited to 512 kbps.

Parameters

car-name: Specifies a global CAR action by its name. This argument must start with a letter, and is a case-sensitive string of 1 to 31 characters. If you do not specify a global CAR action, this command displays information about all global CAR actions.

Examples

# Display information about all global CAR actions.

qos car (interface view)

Use qos car to apply an aggregate CAR action to an interface.

Use undo qos car to remove an aggregate CAR action from an interface.

Syntax

qos car { inbound | outbound } { any | acl [ ipv6 ] acl-number } name car-name

undo qos car { inbound | outbound } { any | acl [ ipv6 ] acl-number }

Default

No aggregate CAR action is applied to an interface.

network-admin

Parameters

inbound: Performs aggregate CAR for incoming packets.

outbound: Performs aggregate CAR for outgoing packets.

any: Performs aggregate CAR for all IP packets.

acl acl-number: Performs aggregate CAR for packets matching an IPv4 ACL. The value range for acl-number is 2000 to 3999.

acl ipv6 acl-number: Performs aggregate CAR for packets matching an IPv6 ACL. The acl-number is in the range of 2000 to 3999.

name car-name: Specifies the name of an aggregate CAR action. This argument must start with a letter, and is a case-sensitive string of 1 to 31 characters.

Usage guidelines

You can apply multiple aggregate CAR actions to an interface. These aggregate CAR actions are executed in the order they are configured.

Examples

# Apply aggregate CAR action aggcar-1 to the inbound packets matching CAR list 1 on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] qos car inbound carl 1 name aggcar-1

Parameters

car-name: Specifies the name of the global CAR action. This argument must start with a letter, and is a case-sensitive string of 1 to 31 characters.

aggregative: Specifies the global CAR action as an aggregate CAR action.

cir committed-information-rate: Specifies the CIR in kbps, which is an average traffic rate. The value range for committed-information-rate is 8 to 10000000.

cbs committed-burst-size: Specifies the CBS in bytes. The value range for committed-burst-size is 1000 to 1000000000. The default value for this argument is the product of 62.5 and the CIR.

ebs excess-burst-size: Specifies the EBS in bytes. The value range for excess-burst-size is 0 to 1000000000. If the PIR is configured, the default EBS is the product of 62.5 and the PIR.

pir peak-information-rate: Specifies the PIR in kbps. The value range for peak-information-rate is 8 to 10000000.

green action: Specifies the action to take on packets that conform to CIR. The default setting is pass.

red action: Specifies the action to take on the packet that conforms to neither CIR nor PIR. The default setting is discard.

yellow action: Specifies the action to take on packets that conform to PIR but not to CIR. The default setting is pass.

action: Specifies the action to take on packets:

·     discard: Drops the packet.

·     pass: Permits the packet to pass through.

·     remark-dot1p-pass new-cos: Sets the 802.1p priority value of the 802.1p packet to new-cos and permits the packet to pass through. The new-cos argument is in the range of 0 to 7.

·     remark-dscp-pass new-dscp: Sets the packet with a new DSCP value and permits the packet to pass through. The new-dscp argument is in the range of 0 to 63. Alternatively, you can specify the new-dscp argument with af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs1, cs2, cs3, cs4, cs5, cs6, cs7, default, or ef.

Usage guidelines

To use two rates for aggregate CAR, configure the qos car command with the pir peak-information-rate option. To use one rate for aggregate CAR, configure the qos car command without the pir peak-information-rate option.

An aggregate CAR action takes effect only after it is applied to an interface.

Examples

# Configure aggregate CAR action aggcar-1, where CIR is 25600, CBS is 512000, and red packets are dropped.

<Sysname> system-view

[Sysname] qos car aggcar-1 aggregative cir 25600 cbs 512000 red discard

Parameters

car-name: Specifies a global CAR action by its name. This argument must start with a letter, and is a case-sensitive string of 1 to 31 characters. If you do not specify a global CAR action, this command clears statistics for all global CAR actions.
