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.
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, 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.
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.
outbound-interface interface-type interface-number	Matches an output interface specified by its type and number.
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.
service-dot1p dot1p-value&<1-8>	Matches 802.1p priority values in outer VLAN tags. The dot1p-value&<1-8> argument specifies a space-separated list of up to eight 802.1p priority values. The value range for the dot1p-value argument is 0 to 7.
service-vlan-id vlan-id-list	Matches VLAN IDs in outer VLAN tags. The vlan-id-list argument specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN or a range of VLANs in the form of vlan-id1 to vlan-id2. The value for vlan-id2 must be greater than or equal to the value for vlan-id1. The value range for the vlan-id argument is 1 to 4094. You can use this option to match single-tagged packets.
source-mac mac-address	Matches a source MAC address. This option takes effect only on Ethernet interfaces.
tunnel-id tunnel-id	Matches a VXLAN tunnel ID. For the traffic class to take effect, the tunnel must be a VXLAN tunnel.
vxlan { any \| vxlan-id }	Matches a VXLAN ID. If the device acts as an intermediate device in a VXLAN network, it supports matching VXLAN IDs 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:

¡ 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.

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

In a QoS policy applied to the outbound direction of an interface, a match criterion without IPv6 attributes cannot match IPv6 packets. For example, a source MAC address or Layer 2 ACL match criterion cannot match IPv6 packets.

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

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 customer-vlan-id and service-vlan-id match criteria, 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 4294967288 kbps, in increments of 8, or in the range of 1 to 160000000 pps. If you specify the pps keyword, the CIR is specified in pps. If you do not specify the pps keyword, the CIR is specified in kbps.

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

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

pir peak-information-rate: Specifies the peak information rate (PIR) in the range of 8 to 4294967288 kbps, in increments of 8, or in the range of 1 to 160000000 pps. If you specify the pps keyword, the PIR is specified in pps. If you do not specify the pps keyword, the PIR is specified in kbps. The PIR must be specified in the same unit as the CIR.

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.

The CIR must be specified in pps for a traffic policing action applied to a control plane.

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.

Views

Traffic behavior view

Predefined user roles

network-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.

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

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.

A local QoS ID marking action takes effect only when the QoS policy is applied to the inbound direction of an interface, VLANs, or globally.

In an IRF fabric, if you use a QoS policy to mark the local QoS ID of incoming packets on a member device, you cannot match the marked packets by using local QoS IDs in the outbound direction on another member device.

In a VXLAN network, if you use a QoS policy to mark the local QoS ID of incoming packets on a VTEP or VXLAN IP gateway, you cannot match the marked packets by using local QoS IDs in the outbound direction on the remote VTEP or VXLAN IP gateway.

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.

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 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.

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

# Associate traffic class database with traffic behavior test in QoS policy user1, and insert traffic class database before an existing traffic class named class-a.

qos apply policy (Ethernet service instance view, interface view, control plane view)

Use qos apply policy to apply a QoS policy to an Ethernet service instance, 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 | outbound } [ share-mode ]

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

Default

No QoS policy is applied.

Views

Control plane view

Ethernet service instance view

Interface view

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 or control plane view.

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 IRF member device with the same QoS policy applied in one direction share one QoS and ACL resource. In the inbound direction, this mode is used by default.

If you specify the share-mode keyword when applying a QoS policy to the outbound direction of a Layer 2 or Layer 3 Ethernet interface, follow these restrictions and guidelines:

· The switch supports a maximum of seven QoS policies in sharing mode.

· The CAR action and class-based accounting action are not supported in the QoS policy.

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 steps:

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 for each type) can be applied to the inbound 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.

Only one generic QoS policy can be applied to the outbound direction of an interface.

A traffic class cannot match IPv6 packets if the following conditions exist:

· It uses a Layer 2 ACL that contains a MAC address match rule.

· The QoS policy is applied to the outbound direction.

You can apply a QoS policy to only the inbound direction of an Ethernet service instance. For configuration commands for Ethernet service instances, see VXLAN Command Reference.

If a class uses control plane protocols or control plane protocol groups as match criteria, the action in the associated traffic behavior can only be car or the combination of car and accounting. Only the cir keyword in the car action can be applied correctly.

You can apply a QoS policy to only the inbound direction of a Layer 2 or Layer 3 aggregate interface

qos apply policy (user profile view)

Use qos apply policy to apply a QoS policy to a user profile.

Use undo qos apply policy to remove a QoS policy applied to a user profile.

Syntax

qos apply policy policy-name { inbound | outbound }

undo qos apply policy policy-name { inbound | outbound }

Default

No QoS policy is applied to a user profile.

Views

User profile view

Predefined user roles

network-admin

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 traffic of the device (traffic sent by online users).

outbound: Applies the QoS policy to the outgoing traffic of the device (traffic received by online users).

Usage guidelines

Deleting a user profile also removes the QoS policies applied to the user profile.

For a user profile to be active, the QoS policy applied in user profile view cannot be empty. A user profile supports only the car and accounting actions in a QoS policy.

Examples

# Apply QoS policy test to incoming traffic of user profile user.

<Sysname> system-view

[Sysname] user-profile user

[Sysname-user-profile-user] qos apply policy test outbound

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 | outbound }

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

Default

No QoS policy is applied globally.

Views

System view

Predefined user roles

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.

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.

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 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.

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

Predefined user roles

network-admin

Parameters

priority-value: Specifies a priority value. If the dscp keyword is not specified, this argument specifies the port priority in the range of 0 to 7. If the dscp keyword is specified, this argument specifies the DSCP value to be set for packets, in the range of 0 to 63.

Usage guidelines

When no priority trust mode is configured for an interface, the interface uses the port priority as the 802.1p priority for priority mapping. If the qos priority dscp priority-value command is configured, the interface modifies the DSCP value of Layer 3 packets in addition to performing priority mapping.

This command is no longer in effect after a priority trust mode is configured.

Examples

# Set the port priority of Twenty-FiveGigE 1/0/1 to 2, and modify the DSCP value of Layer 3 packets to 20.

<Sysname> system-view

[Sysname] interface twenty-fivegige 1/0/1

Predefined user roles

network-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 38000 cell resources. A cell resource is 208 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 38000 cell resources. A cell resource is 208 bytes.

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.

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.

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

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

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

action: Specifies the action to take on packets:

· discard: Drops the packet.

· pass: Permits the packet to pass through.

· remark-dot1p-pass new-cos: Sets the 802.1p priority value of the 802.1p packet to new-cos and permits the packet to pass through. The new-cos argument is in the range of 0 to 7.

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

Parameters

protocol-list&<1-8>: Specifies a space-separated list of up to eight control plane protocol items. Each item specifies a control plane protocol or a range of control plane protocol s in the form of protocol-name1 to protocol-name2.

all: Specifies all control plane protocols.

Usage guidelines

A device provides the data plane and the control plane.

· Data plane—The units at the data plane are responsible for receiving, transmitting, and switching (forwarding) packets, such as various dedicated forwarding chips. They deliver super processing speeds and throughput.

· Control plane—The units at the control plane are processing units running most routing and switching protocols. They are responsible for protocol packet resolution and calculation, such as CPUs. Compared with data plane units, the control plane units allow for great packet processing flexibility but have lower throughput.

If protocol packets sent to the control plane are dropped, the protocol operation will be affected. You can configure control plane packet-drop logging. The device regularly generates and sends logs to the information center. For information about configuring the information center, see Network Management and Monitoring Configuration Guide.

Examples

# Enable packet-drop logging for all control plane protocols.
