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. Only SF interface modules support matching the inner header information of VXLAN packets. 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.
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 5.
forwarding-layer { bridge \| route }	Matches Layer 2 forwarded packets or Layer 3 forwarded packets. · bridge—Matches Layer 2 forwarded packets. · route—Matches Layer 3 forwarded 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.
protocol protocol-name	Matches a protocol. The protocol-name argument can be ip or ipv6.
qos-local-id local-id-value	Matches a local QoS ID in the range of 1 to 4095. This option is supported only in the inbound direction.

Usage guidelines

If a Layer 2 ACL rule contains a MAC address match criterion, the ACL rule cannot match IPv6 packets in a QoS policy applied to the outbound direction.

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.

For a QoS policy to match IPv6 packets in the outbound direction of interfaces on an SF interface card or IPv6 packets on an SE interface card, you must specify IPv6 packet match criteria (for example, configure a rule to match the IPv6 protocol type) in the corresponding traffic classes.

On an SF interface card:

For passing VXLAN packets, a QoS policy applied in the inbound direction cannot match the source MAC address, customer-vlan-id , or customer-dot1p.

For passing GRE and NVGRE packets, a QoS policy applied in the inbound direction cannot match the source MAC or customer-vlan-id.

Parameters

cir committed-information-rate: Specifies the committed information rate (CIR) in the range of 16 to 100000000, which must be a multiple of 8.

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 the range of 512 to 67092480 bytes. The value must be an integral multiple of 512.

pir peak-information-rate: Specifies the peak information rate (PIR) in the range of 16 to 100000000 kbps, in increments of 8. 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.

Examples

# Configure a CAR action in traffic behavior database:

· Set the CIR to 256 kbps, CBS to 51200 bytes, and EBS to 0.

network-admin

mdc-admin

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. If track entries are specified, the redirection feature verifies the reachability of the next hop IP addresses based on the Track detection result. If both primary and secondary next hop IP addresses are unreachable, traffic redirection to a next hop does not take effect.

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.

track track-entry-number: Specifies a track entry by its ID in the range of 1 to 1024. Different track entries can be specified for primary and secondary IP addresses. By specifying track entries, you can associate traffic redirection with detection modules, such as NQA and BFD (see High Availability Configuration Guide).

fail-action: Specifies the action to take on packets if the next hop IP address does not exist. Without this parameter configured, the device discards packets if the next hop IP address does not exist.

discard: Discards packets.

forward: Forwards packets.

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.

Usage guidelines

A DSCP marking action in a QoS policy takes effect only when it is applied in the inbound direction.

The new DSCP value marked on the input interface for a packet does not take effect when it is forwarded out of the output interface if the following conditions exists:

· The input interface and output interface are on different interface modules.

· The card where the output interface resides is an SF interface module.

Examples

# Configure traffic behavior database to mark matching traffic with DSCP 6.

<Sysname> system-view

[Sysname] traffic behavior database

[Sysname-behavior-database] remark dscp 6

remark ip-precedence

Use remark ip-precedence to configure an IP precedence marking action in a traffic behavior.

Use undo remark ip-precedence to restore the default.

Syntax

remark ip-precedence ip-precedence-value

undo remark ip-precedence

Default

No IP precedence marking action is configured.

[Sysname-behavior-database] remark ip-precedence 6

remark local-precedence

Use remark local-precedence to configure a local precedence marking action in a traffic behavior.

Use undo remark local-precedence to restore the default.

Syntax

remark [ green | red | yellow ] local-precedence local-precedence-value

undo remark [ green | red | yellow ] local-precedence

Default

No local precedence marking action is configured.

Views

mdc-admin

Parameters

green: Specifies green packets.

red: Specifies red 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 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

mdc-admin

Parameters

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

Usage guidelines

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

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

On an SF module:

· To use a QoS policy to mark the local QoS ID for IPv6 packets through a QoS policy, you must configure the corresponding traffic class to match the IPv6 protocol.

· Do not configure both a local QoS ID match criterion and a local QoS ID marking action.

· Only the class-based accounting action is supported in a traffic behavior that contains a local QoS ID marking action.

· Only one local QoS ID match criterion is supported in a QoS policy.

· If an ACL in a traffic class needs to match IPv6 packets, first configure it to match IPv6 packets.

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

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

Use undo remark service-vlan-id to restore the default.

Syntax

Parameters

vlan-id: Specifies an SVLAN ID in the range of 1 to 4094.

Usage guidelines

An SVLAN marking action in a QoS policy takes effect only when it is applied to the inbound direction.

For a packet with its SVLAN ID marked to be sent out of the output interface, make sure the SVLAN ID before marking is allowed on the output interface and the VLAN tag is not removed.

Examples

# Configure traffic behavior b1 to mark matching packets with SVLAN 222.

<Sysname> system-view

[Sysname] traffic behavior b1

[Sysname-behavior-b1] remark service-vlan-id 222

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

Parameters

ipv6-matching: Specifies an IPv6-matching QoS policy. This keyword is supported only in interface view or Ethernet service instance view.

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

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

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

tcp-erspan: Specifies a TCP ERSPAN-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 or VSI view.

Usage guidelines

A QoS policy configured with CBQ is not supported in control plane view or control-plane management view.

You can use the following commands to match protocol packets sent to the CPU for a QoS policy applied to a control plane:

· if-match control-plane protocol

· if-match control-plane protocol-group

· if-match acl

When you use the if-match acl command to match protocol packets sent to the CPU, follow these restrictions and guidelines:

¡ The used ACL must be an advanced ACL.

¡ You must specify TCP or UDP for the protocol argument in the rule.

¡ You must specify a source port or destination port by using the eq operator in the rule.

For example, an IPv4 advanced ACL that contains a rule permit tcp source-port eq 80 statement can match TCP packets sent to the CPU.

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.

An IPv6-matching QoS policy is used for traffic classes containing IPv6 ACL match criteria. Other QoS policy types do not distinguish between IPv4 and IPv6.

In some scenarios, you need to apply a QoS policy for matching IPv4 packets and a QoS policy for matching IPv6 packets to the same direction of the same object. In this case, you use a generic QoS policy for matching IPv4 packets and an IPv6-matching QoS policy.

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

Usage guidelines

This function enables ECN on all queues configured with WRED parameters. The queues can be queues configured with the qos wred queue commands in interface view and queues configured in a WRED table.

If you enable ECN globally and enable ECN for a queue by using the qos wred queue ecn or queue ecn command, how ECN takes effect depends on the device model.

Examples

# Enable WRED on Ten-GigabitEthernet 3/0/1, and use the IP precedence for drop probability calculation.

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 16383.

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 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 3/0/1:

· 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

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.

cir committed-information-rate: Specifies the CIR in kbps, which is an average traffic rate. The value range for committed-information-rate is 16 to 100000000, in increments of 8.

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 PIR in kbps. The value range for peak-information-rate is 16 to 100000000, in increments of 8.

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. A QoS policy containing an aggregate CAR action can be applied to only one direction in the same view.

If the action for yellow packets is configured as discard, the action for red packets can only be configured as discard.

Examples

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

<Sysname> system-view
