Parameters

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

Table 2 Available match criteria

Option	Description
acl [ ipv6 \| mac \| user-defined ] { acl-number \| name acl-name } [ inner ]	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. · 5000 to 5999 for user-defined 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. If you use the rule [ rule-id ] { deny \| permit } command to match packets, the inner keyword matches the inner header information of VXLAN packets. If you do not specify this keyword, the ACL matches the header information of non-encapsulated packets or the outer header information of VXLAN packets. If you use the rule [ rule-id ] { deny \| permit } vxlan command to match inner header information of VXLAN packets, you cannot specify the inner keyword in the if-match acl command. If no VPN instance is specified in an ACL rule, the ACL rule takes effect on both non-VPN packets and VPN packets.
any	Matches all packets.
control-plane protocol protocol-name&<1-8>	Matches control plane protocols. The protocol-name&<1-8> argument specifies a space-separated list of up to eight system-defined control plane protocols. For available system-defined control plane protocols, see Table 3.
control-plane protocol-group protocol-group-name	Matches a control plane protocol group. The protocol-group-name argument can be critical, exception, important, management, monitor, normal, or redirect.
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	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 5. This option can only match IPv4 packets. To match IPv6 packets by DSCP value, create IPv6 advanced ACL, create a rule to match a DSCP value, and reference the ACL by using the if-match acl ipv6 { acl-number \| name acl-name } command.
forwarding-layer { bridge \| route }	Matches untagged packets. · bridge—Matches Layer 2 untagged packets. · route—Matches Layer 3 untagged packets.
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.

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:

¡ Control plane protocol.

¡ 802.1p priority.

¡ DSCP.

¡ 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.

To use an ACL match criterion, the ACL must already exist.

To match the outer header information of VXLAN packets, you can directly use the options supported by the if-match command.

To match the inner header information of VXLAN packets by using an ACL, use the rule vxlan command to specify the inner fields to match. The used ACL must be an IPv4 advanced ACL or Layer 2 ACL. For an IPv4 advanced ACL, only the inner 5-tuple is supported.

If a traffic class includes two ACL match criteria that match inner and outer packet information, follow these restrictions:

· Each ACL can contain only one rule.

· The rule in the ACL for matching the outer packet information can match only source IP addresses.

To match the 5-tuple and DSCP priority of MPLS packets, use the following if-match commands in a traffic class with the AND operator:

1. if-match mpls { l2vpn | l3vpn }

2. if-match acl

· 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

Parameters

cir committed-information-rate: Specifies the committed information rate (CIR) in the range of 8 to 160000000 kbps, in increments of 8.

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 8 to 160000000 kbps, in increments of 8.

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.

Syntax

remark qos-local-id local-id-value

undo remark qos-local-id

Default

No local QoS ID marking action is configured.

Views

Traffic behavior view

Predefined user roles

network-admin

Parameters

local-id-value: Specifies the local QoS ID to be marked for packets, in the range of 1 to 4095.

Usage guidelines

You can use one QoS policy to mark the local QoS ID for packets in the inbound direction. Then, you can use another QoS policy to apply other QoS features in the outbound direction based on the marked local QoS ID.

If you execute the remark qos-local-id command multiple times in the same traffic behavior, the most recent configuration takes effect.

Examples

# Configure the action of marking packets with local QoS ID 2.

<Sysname> system-view

[Sysname] traffic behavior database

[Sysname-behavior-database] remark qos-local-id 2

remark service-class

Use remark service-class to configure an action of marking the MPLS TE service class in a traffic behavior.

Use undo remark service-class to restore the default.

Syntax

remark service-class service-class-value

undo remark service-class

Default

No MPLS TE service class marking action is configured.

Views

Traffic behavior view

Predefined user roles

network-admin

Parameters

service-class-value: Specifies the MPLS TE service class in the range of 0 to 7.

Usage guidelines

If the remark service-class command is configured in a QoS policy:

· The action of marking the MPLS TE service class takes effect only when the QoS policy is applied to the inbound direction of an interface. To identify the traffic behaviors that do not take effect, use the display qos policy interface command.

· The traffic class can only match packets by the IP 5-tuple (source IP address, source port number, destination IP address, destination port number, and protocol type), DSCP priority, and MPLS EXP value. Only one MPLS TE service class marking action can be configured for packets with the same MPLS EXP value on an interface. To modify the MPLS TE service class to be marked, you must remove the existing service class setting and configure a new service class value.

If you execute the remark service-class command multiple times in the same traffic behavior, the most recent configuration takes effect.

You can use the mpls te service-class command to set the MPLS TE service class. For more information, see MPLS TE commands in MPLS Command Reference.

Examples

# Configure an action of marking the MPLS TE service class as 2.

<Sysname> system-view

[Sysname] traffic behavior data

[Sysname-behavior-data] remark service-class 2

remark service-vlan-id

Use remark service-vlan-id to configure an SVLAN marking action in a traffic behavior.

network-admin

Parameters

classifier-name: Specifies a traffic class by its name, a case-sensitive string of 1 to 31 characters.

behavior-name: Specifies a traffic behavior by its name, a case-sensitive string of 1 to 31 characters.

insert-before before-classifier-name: Inserts the new traffic class before an existing traffic class in the QoS policy. The before-classifier-name argument specifies an existing traffic class by its name, a case-sensitive string of 1 to 31 characters. If you do not specify the insert-before before-classifier-name option, the new traffic class is placed at the end of the QoS policy.

Usage guidelines

A traffic class can be associated only with one traffic behavior in a QoS policy.

If the specified traffic class or traffic behavior does not exist, the system defines a null traffic class or traffic behavior.

Examples

# Associate traffic class database with traffic behavior test in QoS policy user1.

<Sysname> system-view

[Sysname] qos policy user1

[Sysname-qospolicy-user1] classifier database behavior test

qos apply policy (interface view, control plane view)

Use qos apply policy to apply a QoS policy to an interface or control plane.

Use undo qos apply policy to remove an applied QoS policy.

Syntax

qos apply [ accounting | mirroring | remarking ] policy policy-name { inbound [ extension ] | outbound } [ share-mode ]

undo qos apply [ accounting | mirroring | remarking ] policy policy-name { inbound | outbound }

Default

No QoS policy is applied.

Views

Predefined user roles

network-admin

Parameters

accounting: Specifies an accounting-type QoS policy. This keyword is supported only in interface view.

mirroring: Specifies a mirroring-type QoS policy. This keyword is supported only in interface view.

remarking: Specifies a marking-type QoS policy. This keyword is supported only in interface view.

policy-name: Specifies a QoS policy by its name, a case-sensitive string of 1 to 31 characters.

inbound: Applies the QoS policy to incoming traffic.

outbound: Applies the QoS policy to outgoing traffic. This keyword is not supported in Ethernet service instance view, control plane view, or control-plane management view.

extension: Applies the QoS policy in extended mode.

share-mode: Applies the QoS policy in sharing mode to a Layer 2 or Layer 3 Ethernet interface. In this mode, all interfaces on an interface card with the same QoS policy applied in one direction share one QoS and ACL resource.

Usage guidelines

The display qos policy interface command output for an interface also contains packet statistics for all interfaces that share the QoS and ACL resource with the interface.

If you specify the share-mode keyword when applying a QoS policy to an interface, follow these restrictions and guidelines:

· All interfaces on an interface module with the QoS policy applied in one direction share one QoS and ACL resource.

If the share-mode keyword is not specified, each interface uses one QoS and ACL resource in one direction.

· All interfaces that share one QoS and ACL resource evenly share the set CIR if a traffic policing action is configured in the QoS policy.

If the share-mode keyword is not specified, the bandwidth of each interface can be limited to the CIR.

· You cannot specify the share-mode keyword when applying an ACL to the same direction of the interface. For more information about applying an ACL to an interface, see the packet-filter (interface view) command in ACL commands.

You cannot change the sharing mode dynamically after a QoS policy is applied to an interface. To change the sharing mode for an applied QoS policy, perform the following tasks:

1. Remove the QoS policy from the interface.

2. Reapply the QoS policy with or without the share-mode keyword specified.

A maximum of four QoS policies (one generic, one accounting-type, one mirroring-type, and one marking-type) can be applied to one direction of an interface. Different actions can be taken on the same traffic class if QoS policies of different types are applied to an interface.

You can apply a QoS policy to one direction of an interface in either extended mode or common mode, but not both. A QoS policy applied in extended mode uses more hardware resources but supports limited parameters than that applied in common mode.

On the same interface, if you perform two of the following tasks, the tasks performed later might do not take effect due to lack of hardware resources:

· Apply a QoS policy containing IPv6 address match criteria to the outbound direction.

· Enable IPv6 NetStream for outbound traffic by using the ipv6 netstream outbound command (see IPv6 NetStream commands in Network Management and Monitoring Command Reference).

· Enable statistics counting for outgoing Layer 3 packets by using the statistics l3-packet enable outbound command (see IPv6 basics or IP performance optimization commands in Layer 3—IP Services Command Reference).

Examples

# Apply generic QoS policy USER1 to the outgoing traffic of HundredGigE 1/0/1.

<Sysname> system-view

[Sysname] interface hundredgige 1/0/1

qos apply policy global

Use qos apply policy global to apply a QoS policy globally.

Use undo qos apply policy global to remove a globally applied QoS policy.

Syntax

qos apply [ accounting | mirroring | remarking ] policy policy-name global { inbound [ extension ] | outbound }

undo qos apply [ accounting | mirroring | remarking ] policy policy-name global { inbound | outbound }

Default

No QoS policy is applied globally.

network-admin

Parameters

accounting: Specifies an accounting-type QoS policy.

mirroring: Specifies a mirroring-type QoS policy.

remarking: Specifies a marking-type QoS policy.

policy-name: Specifies a QoS policy by its name, a case-sensitive string of 1 to 31 characters.

inbound: Applies the QoS policy to the incoming packets on all interfaces.

outbound: Applies the QoS policy to the outgoing packets on all interfaces.

extension: Applies the QoS policy in extended mode.

Usage guidelines

A global QoS policy takes effect on all incoming or outgoing traffic depending on the direction in which the QoS policy is applied.

A maximum of four QoS policies (one generic, one accounting-type, one mirroring-type, and one marking-type) can be applied to one direction globally.

If you do not specify the accounting, mirroring, or remarking keyword, this command applies a generic QoS policy globally.

Examples

# Globally apply generic QoS policy user1 to the incoming traffic.

<Sysname> system-view

[Sysname] qos apply policy user1 global inbound

# Globally apply mirroring-type QoS policy user2 to the incoming traffic.

<Sysname> system-view

[Sysname] qos apply mirroring policy user2 global inbound

qos policy

Use qos policy to create a QoS policy and enter its view, or enter the view of an existing QoS policy.

Use undo qos policy to delete a QoS policy.

Syntax

qos [ accounting | mirroring | remarking ] policy policy-name

undo qos [ accounting | mirroring | remarking ] policy policy-name

Default

No QoS policies exist.

Views

System view

Predefined user roles

network-admin

Parameters

accounting: Identifies the QoS policy as an accounting-type QoS policy.

mirroring: Identifies the QoS policy as a mirroring-type QoS policy.

remarking: Identifies the QoS policy as a marking-type QoS policy.

policy-name: Specifies a name for the QoS policy, a case-sensitive string of 1 to 31 characters.

Usage guidelines

If you do not specify the accounting, mirroring, or remarking keyword when creating a QoS policy, a generic QoS policy is created.

QoS policies of different types cannot use the same policy name.

Do not use the accounting, mirroring, or remarking word or the first letters of any one of them as a policy name. If you do so, no information is displayed when you execute the display qos policy user-defined policy-name command, because the system will recognize such a policy name as a command keyword.

A generic QoS policy can be applied to all supported destinations and can contain all actions. An accounting-type QoS policy can be applied to only interfaces or globally and can contain only class-based accounting actions. A mirroring-type QoS policy can be applied to only interfaces or globally and can contain only mirroring actions. A marking-type QoS policy can be applied to only interfaces or globally and can contain only marking actions.

To delete a QoS policy that has been applied to an object, you must first remove the QoS policy from the object.

Examples

# Create a generic QoS policy named user1.

<Sysname> system-view

[Sysname] qos policy user1

[Sysname-qospolicy-user1]

# Create an accounting-type QoS policy named user2.

<Sysname> system-view

Parameters

all: Specifies all queues.

queue-id: Specifies a queue by its ID. The value range for this argument is 0 to 7.

drop-level drop-level: Specifies a drop level. This argument is a consideration for dropping packets. The value 0 corresponds to green packets, the value 1 corresponds to yellow packets, and the value 2 corresponds to red packets. If you do not specify a drop level, the subsequent configuration takes effect on the packets in the queue regardless of the drop level.

low limit low-limit: Specifies the lower limit for the average queue length. The value range for low-limit is 0 to 268435455 cell resources. A cell resource is 1024 bytes.

high-limit high-limit: Specifies the upper limit for the average queue length. The upper limit must be greater than the lower limit. The value range for high-limit is 0 to 268435455 cell resources. A cell resource is 1024 bytes.

discard-probability discard-prob: Specifies the denominator for drop probability calculation. The greater the denominator, the smaller the calculated drop probability. The value range for discard-prob is 0 to 100.

Usage guidelines

When the average queue size is smaller than the lower threshold, no packet is dropped. When the average queue size is between the lower threshold and the upper threshold, the packets are dropped at random. The longer the queue is, the higher the drop probability is. When the average queue size exceeds the upper threshold, subsequent packets are dropped.

Examples

# In queue-based WRED table queue-table1, configure the following drop-related parameters for packets in queue 1:

· The drop level is 1.

· The lower limit for the average queue length is 10.

· The upper limit for the average queue length is 20.

· The drop probability is 30%.

Parameters

queue-id: Specifies a queue by its ID in the range of 0 to 7.

Usage guidelines

When both the receiver and sender support ECN, the device can notify the peer end of the congestion status by identifying and setting the ECN flag. ECN avoids deteriorating congestion.

Examples

# In WRED table queue-table1, enable ECN for queue 1.

Parameters

queue-id: Specifies a queue by its ID. The value range for this argument is 0 to 7.

weighting-constant exponent: Specifies the WRED exponent for average queue length calculation. The value range for exponent is 0 to 15.

Usage guidelines

The bigger the exponent is, the less sensitive the average queue size is to real-time queue size changes. The average queue size is calculated using the formula:

Average queue size = previous average queue size × (1-2-n) + current queue size × 2-n,

where n can be configured with the qos wred weighting-constant command.

Examples

# In WRED table queue-table1, set the exponent for average queue length calculation to 12 for queue 1.

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.

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 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 committed-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.

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
