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. You can use the inner keyword to match the inner header information of VXLAN packets. For example, a rule permit ip source 10.0.0.0 0.255.255.255 statement matches the inner source IP address of VXLAN packets if the inner keyword is specified in the if-match acl command. The statement matches the source IP address of non-VXLAN packets or the outer source IP address of VXLAN packets if the inner keyword is not specified. If you specify the inner keyword in the if-match acl command, you must also specify it when executing the undo 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:

¡ Control plane protocol.

¡ 802.1p priority.

¡ DSCP.

¡ IP precedence.

¡ MPLS EXP.

¡ MPLS label.

¡ 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.

· An ACL can only match the following inner header information of VXLAN packets:

¡ Source IP address.

¡ Destination IP address.

¡ Source port number.

¡ Destination port number.

¡ Transport protocol type.

· 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 includes both the control-plane protocol or control-plane protocol-group criterion and other criteria, the QoS policy that contains the traffic class cannot be applied correctly.

If any traffic class in a QoS policy includes the control-plane protocol or control-plane protocol-group match criterion, the QoS policy can be applied only to a control plane.

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

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.

Usage guidelines

You can apply a QoS policy that contains a traffic policing action to the inbound or outbound direction of an interface, VLANs, a control plane, or globally. However, the traffic policing action takes effect only when the QoS policy is applied to the inbound direction.

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.

Default

MAC address learning is enabled for a traffic behavior.

Views

Traffic behavior view

Predefined user roles

network-admin

mdc-admin

Usage guidelines

To prevent the MAC address table from being saturated when the device is experiencing attacks, disable MAC address learning. For example, you can disable MAC address learning to prevent the device from being attacked by a large number of frames with different source MAC addresses.

Disabling MAC address learning in a traffic behavior takes effect only if the QoS policy is applied to the inbound direction of an interface or globally.

Disabling MAC address learning has the following impacts:

· The device does not learn new MAC addresses of packets that match the QoS policy and therefore cannot update MAC address changes in real time.

· The device floods packets that do not match an entry in the MAC address table.

As a best practice, configure broadcast storm suppression on the interface that has the QoS policy applied. For information about broadcast storm suppression, see Layer 2—LAN Switching Configuration Guide.

· The device does not delete existing MAC addresses until the aging timer expires.

To delete the existing MAC addresses, delete them manually or wait for the aging timer to expire.

Predefined user roles

network-admin

mdc-admin

Parameters

vlan-id vlan-id: Specifies the VLAN ID to be added in the outer VLAN tag, in the range of 1 to 4094.

Usage guidelines

For a QoS policy that contains a nesting action to take effect on a Type H card, make sure both the downlink port and uplink port permit the single-tagged packets matching the QoS policy. The double-tagged packets are forwarded in the device based on the inner VLAN tag.

If a QoS policy contains an outer VLAN tag adding action, apply it only to the incoming traffic of an interface.

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

An outer VLAN tag adding action takes effect only when the QoS policy is applied to the inbound direction of an interface, VLANs, or globally.

This command does not take effect on packets forwarded by a VXLAN overlay network.

Parameters

value: Specifies the protocol packet rate in pps. The value range for this argument is 1 to 1048575. The device converts the specified value to the nearest integral multiple of 43 that is not 0.

Usage guidelines

Protocol packet rate limiting can protect the CPU against protocol packet attacks.

A protocol packet rate limiting action takes effect only when the QoS policy is applied to a control plane.

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

Examples

Parameters

cpu: Redirects traffic to the CPU.

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

tunnel-group group-id: Redirects traffic to a tunnel group specified by its ID. The value range for the group-id argument is 1 to 32. For information about tunnel groups, see tunneling in Layer 3—IP Services Configuration Guide.

Usage guidelines

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

The redirecting action in a QoS policy takes effect only on Layer 2 packets, and does not take effect on Layer 3 packets.

Examples

# Configure redirecting traffic to FortyGigE 1/0/1 in traffic behavior database.

Parameters

service-class-value: Specifies the MPLS TE service class to be marked for packets. The value range for this argument is 0 to 7.

Usage guidelines

This command is used only in CBTS to mark the MPLS TE service class for packets. For more information about CBTS, see MPLS TE in MPLS Configuration Guide.

You can use the mpls te service-class command to set an MPLS TE service class value for a tunnel. For more information about this command, see MPLS TE commands in MPLS Command Reference.

A QoS policy that contains the remark service-class command can only be applied globally.

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

For an HF card, if the TCAM operating mode is mixed, the traffic class associated with the MPLS TE service class marking action can match packets by using the following criteria:

· Source IP address.

· Destination IP address.

· Source MAC address.

· Destination MAC address.

· Port number.

· DSCP value.

If the TCAM operating mode is not mixed, the traffic class can match packets by using only the DSCP value.

For a card other than HF, the traffic class associated with the MPLS TE service class marking action can match packets by using only the DSCP value.

For information about TCAM operating modes, see device management in Fundamentals Configuration Guide.

mdc-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.

mode dcbx: Specifies that the class-behavior association applies only to the DCBX. For more information about DCBX, see Layer 2—LAN Switching Configuration Guide.

mode loose: Specifies that a class-behavior association is applied in loose mode. This keyword takes effect only when a QoS policy is applied to a control plane.

mode qppb-manipulation: Specifies that the class-behavior association applies only to QPPB. The if-match qos-local-id command in the class sets the same local QoS ID as the apply qos-local-id command in the BGP routing policy. For more information about routing policies, see Layer 3—IP Routing Configuration Guide.

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.

The mode loose keyword allows you to limit the rate of protocol packets from a specific interface to the control plane. The configuration procedure is as follows:

1. Create an ACL, and configure a rule to match protocol packets.

2. Create a traffic class with AND operator, and execute the commands in the if-match acl and if-match inbound-interface traffic class.

3. Create a traffic behavior, configure an action.

4. Create a QoS policy, and associate the traffic class and the traffic behavior and specify the mode loose keyword.

5. Apply the QoS policy to a control plane.

The applied QoS policy takes effect on only the protocol packets from the interface specified in the if-match inbound-interface command to the control plane.

Parameters

accounting: Specifies an accounting-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 or control plane view.

extension: Applies the QoS policy in extended mode to a Layer 2 or Layer 3 Ethernet interface. You can apply a QoS policy to one direction of an interface either with or without the extension keyword, but not both. A QoS policy applied with the extension keyword uses more hardware resources but supports limited parameters than that applied without the extension keyword. This keyword is available only on HF cards. Before using this keyword, you must set the TCAM operating mode to acl by using the hardware-resource tcam command. For information about this command, see device management commands in Fundamentals Command Reference.

share-mode: Applies the QoS policy in sharing mode to a Layer 2 Ethernet interface, Layer 3 Ethernet interface, or VSI interface. In this mode, all Layer 2 Ethernet interfaces, Layer 3 Ethernet interfaces, or VSI interfaces on an interface card with the same QoS policy applied in one direction share one QoS and ACL resource. For Ethernet interfaces, the device has four QoS and ACL resources that can be shared in each direction separately. For VSI interfaces, the device has three QoS and ACL resources that can be shared in each direction separately. The device supports the sharing mode for packet filtering, QoS policy, and policy-based routing. Policy-based routing supports the sharing mode only in the inbound direction. If all QoS and ACL resources that can be shared are used, they can be reused after they are released.

Usage guidelines

For configuration commands for Ethernet service instances, see MPLS L2VPN or VPLS in MPLS Command Reference or see VXLAN Command Reference.

A maximum of three QoS policies (one for each 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 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.

If you specify the share-mode keyword when applying a QoS policy containing a traffic policing action to interfaces, all interfaces that share one QoS and ACL resource evenly share the set CIR. If the share-mode keyword is not specified, the bandwidth of each interface can be limited to the CIR.

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 traffic behavior takes effect only on matching Layer 3 packets and does not take effect on matching Layer 2 packets if the following conditions exist:

· The associated traffic class contains an IPv4 ACL.

· The QoS policy is applied to the outbound direction of an interface.

A traffic behavior takes effect only on matching Layer 3 packets and does not take effect on matching Layer 2 packets if the following conditions exist:

· The associated traffic class contains an IPv6 ACL.

· The dscp dscp option is configured in an ACL rule.

· The QoS policy is applied to the outbound direction of an interface.

A QoS policy cannot be applied to the outbound direction of an interface if the following conditions exist:

· A traffic class contains an IPv6 ACL.

· The source IPv6 address and destination IPv6 address match criteria are configured in a rule of the ACL.

Parameters

accounting: Specifies an accounting-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.

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 three QoS policies (one generic, one accounting-type, and one marking-type) can be applied to one direction globally.

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

A traffic behavior takes effect only on matching Layer 3 packets and does not take effect on matching Layer 2 packets if the following conditions exist:

· The associated traffic class contains an IPv4 ACL.

· The QoS policy is applied to the outbound direction globally.

A traffic behavior takes effect only on matching Layer 3 packets and does not take effect on matching Layer 2 packets if the following conditions exist:

· The associated traffic class contains an IPv6 ACL.

· The dscp dscp option is configured in an ACL rule.

undo qos [ accounting | remarking ] policy policy-name

Default

No QoS policies exist.

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

accounting: Identifies the QoS policy as an accounting-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 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 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 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 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

Usage guidelines

For the remark dot1p command to take effect, this command must be executed.

After an incoming packet is marked according to the remark dot1p command, it is assigned to a queue according to the default dot1p-lp priority map. The 802.1p priority of the packet is modified as its local precedence value before it is sent out.

If you modify the default dot1p-lp priority map, the outgoing packet is enqueued to a different queue, and its 802.1p priority is modified to a different local precedence value.

Parameters

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

Examples

# Modify the 802.1p priority of outgoing packets to the local precedence value on card 3 of member device 1.

Parameters

queue-id: Specifies a queue by its ID. The value range for this argument is 0 to 7 or keywords in Table 25.

Usage guidelines

This command is available only on a WFQ-enabled interface. Queues in the SP group are scheduled with SP, instead of WFQ. The SP group has higher scheduling priority than the WFQ groups.

You must use the qos wfq command to enable WFQ before you configure this command.

Examples

# Enable WFQ on FortyGigE 1/0/1, and assign queue 0 to the SP group.

mdc-admin

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 16383 KB.

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 KB.

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.

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. 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 8 to 160000000, in increments of 8.

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, in increments of 8.

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.

After you configure this command and the qos queue-statistics command, the device collects statistics on packets of each queue. You can use the display qos queue-statistics interface outbound command to display the statistics.

Examples

# Set the packet counting mode to queue.

<Sysname> system-view

[Sysname] statistic mode queue

Do you want to change the packet statistic mode? [Y/N]:y

QPPB commands

bgp-policy

Use bgp-policy to enable QPPB, which transmits the apply ip-precedence and apply qos-local-id configuration through BGP routing policies.

Use undo bgp-policy to restore the default.

Syntax

bgp-policy { destination | source } { ip-prec-map | ip-qos-map } *

undo bgp-policy { destination | source } [ ip-prec-map | ip-qos-map ] *

Default

QPPB is disabled.

Views

Layer 3 Ethernet interface view

VLAN interface view

Predefined user roles

network-admin

mdc-admin

Parameters

destination: Searches the routing table by destination IP address.

source: Searches the routing table by source IP address. If the source keyword is specified, the source IP address is used as the destination address for inverse lookup.

ip-prec-map: Sets an IP precedence value for matching packets.

ip-qos-map: Sets a local QoS ID for matching packets.

Usage guidelines

This command is available only on HF cards. Before configuring this command, you must set the TCAM operating mode to routing by using the hardware-resource tcam command. For information about this command, see device management commands in Fundamentals Command Reference.

The bgp-policy command applies only to the incoming traffic of an interface.

In an MPLS L3VPN, the bgp-policy command is executed after the QoS features are performed in the inbound direction of the PE's public network interface. In any other case, the bgp-policy command is executed before the QoS features.

If you configure either of the following bgp-policy command pairs, both commands in the pair take effect:

· bgp-policy destination ip-prec-map and bgp-policy source ip-qos-map.

· bgp-policy source ip-prec-map and bgp-policy destination ip-qos-map.

If you configure either of the following bgp-policy command pairs, the command with the destination keyword in the pair takes effect:

· bgp-policy destination ip-prec-map and bgp-policy source ip-prec-map.

· bgp-policy destination ip-qos-map and bgp-policy source ip-qos-map.

Examples

# Configure FortyGigE 1/0/1 to get the IP precedence and local QoS ID by looking up routes based on destination IP address.

<Sysname> system-view

[Sysname] interface fortygige 1/0/1

[Sysname-FortyGigE1/0/1] bgp-policy destination ip-prec-map ip-qos-map
