Parameters

match-criteria: Specifies a match criterion. Table 2 shows the available match criteria.

Table 2 Available match criteria

Option

Description

acl [ ipv6 | mac ] { acl-number | name acl-name }

Matches an ACL.

The value range for the acl-number argument is as follows:

·     2000 to 3999 for IPv4 ACLs.

·     2000 to 3999 for IPv6 ACLs.

·     4000 to 4999 for Layer 2 MAC ACLs.

The acl-name argument is a case-insensitive string of 1 to 63 characters, which must start with an English letter. To avoid confusion, make sure the argument is not all.

any

Matches all packets.

customer-dot1p dot1p-value&<1-8>

Matches 802.1p priority values in inner VLAN tags of double-tagged packets.

The dot1p-value&<1-8> argument specifies a space-separated list of up to eight 802.1p priority values. The value range for the dot1p-value argument is 0 to 7.

customer-vlan-id vlan-id-list

Matches VLAN IDs in inner VLAN tags of double-tagged packets.

The vlan-id-list argument specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN or a range of VLANs in the form of vlan-id1 to vlan-id2. The value for vlan-id2 must be greater than or equal to the value for vlan-id1. The value range for the vlan-id argument is 1 to 4094.

destination-mac mac-address [ mac-address-mask ]

Matches a destination MAC address.

This option takes effect only on Ethernet interfaces.

dscp dscp-value&<1-8>

Matches DSCP values.

The dscp-value&<1-8> argument specifies a space-separated list of up to eight DSCP values. The value range for the dscp-value argument is 0 to 63 or keywords shown in Table 4.

ip-precedence ip-precedence-value&<1-8>

Matches IP precedence values.

The ip-precedence-value&<1-8> argument specifies a space-separated list of up to eight IP precedence values. The value range for the ip-precedence-value argument is 0 to 7.

protocol protocol-name

Matches a protocol.

The protocol-name argument can be ip or ipv6.

service-dot1p dot1p-value&<1-8>

Matches 802.1p priority values in outer VLAN tags.

The dot1p-value&<1-8> argument specifies a space-separated list of up to eight 802.1p priority values. The value range for the dot1p-value argument is 0 to 7.

service-vlan-id vlan-id-list

Matches VLAN IDs in outer VLAN tags.

The vlan-id-list argument specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN or a range of VLANs in the form of vlan-id1 to vlan-id2. The value for vlan-id2 must be greater than or equal to the value for vlan-id1. The value range for the vlan-id argument is 1 to 4094.

You can use this option to match single-tagged packets.

source-mac mac-address [ mac-address-mask ]

Matches a source MAC address.

This option takes effect only on Ethernet interfaces.

tunnel-id tunnel-id

Matches a VXLAN tunnel ID. For the traffic class to take effect, the tunnel must be a VXLAN tunnel.

vxlan { any | vxlan-id }

Matches a VXLAN ID.

 

Usage guidelines

In a traffic class with the logical OR operator, you can configure multiple if-match commands for any of the available match criteria.

When you configure a match criterion that can have multiple values in one if-match command, follow these restrictions and guidelines:

·     You can specify up to eight values for any of the following match criteria in one if-match command:

¡     DSCP.

¡     802.1p priority.

¡     IP precedence.

¡     VLAN ID.

·     If a packet matches one of the specified values, it matches the if-match command.

·     To delete a criterion that has multiple values, the specified values in the undo if-match command must be the same as those specified in the if-match command. The order of the values can be different.

When you configure ACL-based match criteria, follow these restrictions and guidelines:

·     The ACL must already exist.

·     The ACL is used for classification only and the permit/deny actions in ACL rules are ignored. Actions taken on matching packets are defined in traffic behaviors.

You can use both AND and OR operators to define the match relationships between the criteria for a class. For example, you can define relationships among three match criteria in traffic class classA as follows:

traffic classifier classB operator and

if-match criterion 1

if-match criterion 2

traffic classifier classA operator or

if-match criterion 3

If a traffic class in a QoS policy includes the customer-vlan-id match criterion, the QoS policy can be applied only to interfaces.

For the customer-vlan-id and service-vlan-id match criteria, you can configure multiple values in one if-match command.

network-admin

Parameters

cir committed-information-rate: Specifies the committed information rate (CIR) in the range of 1 to 160000000 kbps.

cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes. The value range for committed-burst-size is 512 to 256000000, in increments of 512. The default value for this argument is the product of 62.5 and the CIR and must be an integral multiple of 512. When the product is not an integral multiple of 512, it is rounded up to the nearest integral multiple of 512 that is greater than the product. A default value greater than 256000000 is converted to 256000000.

ebs excess-burst-size: Specifies the excess burst size (EBS) in bytes. The value range for excess-burst-size is 0 to 256000000, in increments of 512. If the PIR is configured, the default EBS is the product of 62.5 and the PIR and must be an integral multiple of 512. When the product is not an integral multiple of 512, it is rounded up to the nearest integral multiple of 512. A default value greater than 256000000 is converted to 256000000.

pir peak-information-rate: Specifies the peak information rate (PIR) in the range of 1 to 160000000 kbps.

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

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

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

action: Sets the action to take on the packet:

·     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 DSCP value of the packet to new-dscp and permits the packet to pass through. The new-dscp argument is in the range of 0 to 63.

·     remark-lp-pass new-local-precedence: Sets the local precedence value of the packet to new-local-precedence and permits the packet to pass through. The new-local-precedence argument is in the range of 0 to 7.

Usage guidelines

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

If you execute the car command multiple times in the same traffic behavior, the most recent configuration takes effect.

Examples

# Configure a CAR action in traffic behavior database:

·     Set the CIR to 200 kbps, CBS to 51200 bytes, and EBS to 0.

·     Transmit the conforming packets, and mark the excess packets with DSCP value 0 and transmit them.

Parameters

inbound: Performs CAR for incoming traffic.

outbound: Performs CAR for outgoing traffic.

cir committed-information-rate: Specifies the CIR in kbps. The value range for committed-information-rate is 8 to 160000000.

cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes. The value range for committed-burst-size is 512 to 256000000, in increments of 512. The default value for this argument is the product of 62.5 and the CIR and must be an integral multiple of 512. When the product is not an integral multiple of 512, it is rounded up to the nearest integral multiple of 512 that is greater than the product. A default value greater than 256000000 is converted to 256000000.

ebs excess-burst-size: Specifies the EBS in bytes. The default value for excess-burst-size is 0 bytes. The value range for excess-burst-size is 0 to 256000000.

pir peak-information-rate: Specifies the PIR in kbps. The value range for peak-information-rate is 1 to 160000000.

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.

The conforming traffic is permitted to pass through, and the excess traffic is dropped.

If you execute the qos car command multiple times for the same user profile, the most recent configuration takes effect.

Examples

# Perform CAR for packets received by user profile user. The CAR parameters are as follows:

·     The CIR is 200 kbps.

·     The CBS is 51200 bytes.

Use undo qos car to delete an aggregate CAR action.

Syntax

qos car car-name aggregative cir committed-information-rate [ cbs committed-burst-size [ ebs excess-burst-size ] ] [ green action | red action | yellow action ] *

qos car car-name aggregative cir committed-information-rate [ cbs committed-burst-size ] pir peak-information-rate [ ebs excess-burst-size ] [ green action | red action | yellow action ] *

undo qos car car-name

Parameters

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

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 160000000.

cbs committed-burst-size: Specifies the CBS in bytes. The value range for committed-burst-size is 512 to 256000000, in increments of 512. The default value for this argument is the product of 62.5 and the CIR and must be an integral multiple of 512. When the product is not an integral multiple of 512, it is rounded up to the nearest integral multiple of 512 that is greater than the product. A default value greater than 256000000 is converted to 256000000.

ebs excess-burst-size: Specifies the EBS in bytes. The value range for excess-burst-size is 0 to 256000000, in increments of 512. If the PIR is configured, the default EBS is the product of 62.5 and the PIR and must be an integral multiple of 512. When the product is not an integral multiple of 512, it is rounded up to the nearest integral multiple of 512. A default value greater than 256000000 is converted to 256000000.

pir peak-information-rate: Specifies the PIR in kbps. The value range for peak-information-rate is 8 to 160000000.

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: Remarks 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 used in a QoS policy.

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
