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.

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:

¡ 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.

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

· The ACL must already exist.

· Before defining a criterion to match the inner packet information of VXLAN packets in a traffic class, you must use the if-match vxlan command to define a VXLAN ID match criterion.

· An ACL can only match the following inner packet information:

¡ Source IP address.

¡ Destination IP address.

¡ Source port number.

¡ Destination port number.

¡ Transport protocol type.

· 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.

· 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

For a QoS policy to match outgoing IPv6 packets, you must specify IPv6 packet match criteria (for example, configure a rule to match the IPv6 protocol type) in the corresponding traffic class.

Predefined user roles

network-admin

Parameters

cir committed-information-rate: Specifies the committed information rate (CIR) in the range of 10 to 100000000 kbps, which must be a multiple of 10.

cbs committee-burst-size: Specifies the committed burst size (CBS) in bytes. The value range for committed-burst-size is 512 to 67092480, 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 67092480 is converted to 67092480.

ebs excess-burst-size: Specifies the excess burst size (EBS) in bytes. The value range for excess-burst-size is 0 to 67092480, 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 67092480 is converted to 67092480.

pir peak-information-rate: Specifies the peak information rate (PIR) in the range of 10 to 100000000 kbps, in increments of 10. The PIR and CIR must be configured in the same measurement unit.

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-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.

If the action to take on yellow packets is discard, the action to take on red packets cannot be pass or remark-lp-pass.

Parameters

cpu: Redirects traffic to the CPU.

interface interface-type interface-number: Redirects traffic to an interface specified by its type and number.

next-hop: Redirects traffic to a next hop. For successful traffic redirection, make sure the next hop IP address is reachable. If both primary and secondary next hop IP addresses are specified, make sure a minimum of one IP address is reachable. The redirection feature periodically looks up the routing table to verify the reachability of next hop IP addresses.

ipv4-add1: Specifies the primary next hop IPv4 address. If traffic fails to be redirected to this IPv4 address, the traffic is redirected to the secondary IPv4 address.

ipv4-add2: Specifies the secondary next hop IPv4 address.

ipv6-add1: Specifies the primary next hop IPv6 address. If traffic fails to be redirected to this IPv6 address, the traffic is redirected to the secondary IPv6 address.

ipv6-add2: Specifies the secondary next hop IPv6 address.

slot slot-number: Redirects traffic to an IRF member device specified by its member ID.

Usage guidelines

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

A traffic redirecting action takes effect only when the QoS policy is applied to the inbound direction.

For traffic redirecting to an interface, make sure the VLAN ID of the interface to which the QoS policy is applied is in the allowed VLAN list of the redirected-to interface. Otherwise, the redirected-to interface drops redirected packets.

yellow: Specifies yellow packets.

local-precedence-value: Specifies the local precedence to be marked for packets, in the range of 0 to 7.

Usage guidelines

A local precedence marking action takes effect only when the QoS policy is applied to the inbound direction.

Examples

# Configure traffic behavior database to mark matching traffic with local precedence 2.

<Sysname> system-view

[Sysname] traffic behavior database

[Sysname-behavior-database] remark local-precedence 2

remark qos-local-id

Use remark qos-local-id to configure a local QoS ID marking action in a traffic behavior.

Use undo remark qos-local-id to restore the default.

Syntax

remark qos-local-id [ egress-active ] 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

egress-active: Specifies that the local QoS ID marking action takes effect only in the outbound direction.

local-id-value: Specifies the local QoS ID to be marked for packets, in the range of 1 to 4095. If the egress-active keyword is specified, the value range is 1 to 128.

Usage guidelines

A local QoS ID marking action applied to the inbound direction takes effect in both inbound and outbound directions. 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.

If you configure a local QoS ID match criterion in a traffic class, you cannot configure a local QoS ID marking action in a traffic behavior, and vice versa.

If you configure a local QoS ID marking action in a traffic behavior, you can configure only the accounting action in the traffic behavior.

In a QoS policy, a local QoS ID can be matched for only one time.

You cannot apply a QoS policy in the outbound direction to mark the local QoS ID for packets.

To mark the local QoS ID for IPv6 packets, you must configure the traffic class to match the IPv6 protocol.

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-vlan-id

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

Parameters

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.

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.

Examples

# Globally apply QoS policy user1 to the incoming traffic.

<Sysname> system-view

[Sysname] qos apply policy user1 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.

Syntax

qos [ ipv6-matching | accounting | mirroring | remarking | tcp-erspan ] policy policy-name

undo qos [ ipv6-matching | accounting | mirroring | remarking | tcp-erspan ] policy policy-name

Default

No QoS policies exist.

Views

Predefined user roles

network-admin

Parameters

ipv6-matching: Identifies the QoS policy as an IPv6-matching QoS policy.

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.

tcp-erspan: Identifies the QoS policy as a TCP ERSPAN 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 ipv6-matching, accounting, mirroring, remarking, or tcp-erspan 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 ipv6-matching, accounting, mirroring, remarking, or tcp-erspan 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 IPv6-matching QoS policy can be applied to only interfaces or globally and is used for traffic classes containing IPv6 ACL match criteria. 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 only be applied to 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. A TCP ERSPAN-type QoS policy can be applied to only interfaces or globally and can contain only ERSPAN actions.

In a TCP ERSPAN-type QoS policy, a traffic class matches TCP flags (including ACK, FIN, PSH, RST, SYN, and URG), and a traffic behavior contains an ERSPAN action. For more information about flow mirroring ERSPAN, see Network Management and Monitoring Configuration Guide.

To perform both flow mirroring and rate limiting for traffic, you can configure a generic QoS policy to rate limit traffic and configure a TCP ERSPAN-type QoS policy to perform flow mirroring for traffic. The two types of QoS policies are independent of each other in hardware resources.

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

A QoS policy applied to the inbound direction of an interface cannot match the source MAC address or customer VLAN ID of VXLAN packets.

# Create a QoS policy named user1.

[Sysname] qos policy user1

Parameters

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

low-limit low-limit: Specifies the lower limit for the average queue length. The value range for low-limit is o to 69632.

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 69632 and must be higher than the lower limit.

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

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.

all: Specifies all queues.

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.

This command and the qos wred apply command are mutually exclusive.

Examples

# Configure the following WRED parameters for in queue 1 on Ten-GigabitEthernet 1/0/1:

· 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.

Parameters

all: Specifies all queues.

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

low-limit low-limit: Specifies the lower limit for the average queue length. The value range for low-limit is 0 to 16383 cell resources. A cell resource is 256 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 16383 cell resources. A cell resource is 256 bytes.

Usage guidelines

Examples

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

· The drop level is 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.

cir committed-information-rate: Specifies the CIR in kbps, which is an average traffic rate. The value range for committed-information-rate is 10 to 100000000, in increments of 10.

pir peak-information-rate: Specifies the PIR in kbps. The value range for peak-information-rate is 10 to 100000000, in increments of 10. This option is supported only in aggregate CAR actions.

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: Sets the action to take on the packet:

· 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.

A n 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.
