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.

¡ Local precedence.

¡ MPLS EXP.

· 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.

· 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-match classifier classB

Usage guidelines

To use two rates for traffic policing, configure the car percent command with the pir percent pir-percent option. To use one rate for traffic policing, configure the car percent command without the pir percent pir-percent option.

A QoS policy that uses a traffic behavior configured with percentage-based CAR can be applied in the inbound or outbound direction of an interface.

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

A QoS policy that uses a behavior configured with percentage-based CAR can be applied only to interfaces.

The actual CIR value is cir-percent × bandwidth. The actual PIR value is pir-percent × bandwidth. For a physical interface, the bandwidth is the actual interface bandwidth. For a virtual interface, you must set its expected bandwidth (the default expected bandwidth is 0 kbps). For more information about the expected bandwidth, see Ethernet interface commands in Interface Management Command Reference. In the policy nesting case, the bandwidth used for the CIR and PIR calculations is determined by using the following rules:

· The top policy uses the interface bandwidth.

· A child policy uses the CIR value in GTS configured in the behavior of the child policy.

· If the CIR value is not available in the behavior, the child policy uses the CIR value in GTS configured in the behavior of the higher-level policy.

· If the CIR value is not available in the behavior of the higher-level policy, the child policy uses the interface bandwidth.

Parameters

cir committed-information-rate: Sets the CIR in kbps, which specifies the average traffic rate. The value range for committed-information-rate is 8 to 10000000.

cbs committed-burst-size: Sets the CBS in bytes, which specifies the size of bursty traffic when the actual average rate is not greater than the CIR. The value range for committed-burst-size is 1000 to 1000000000. The default CBS is the product of 62.5 and the CIR.

ebs excess-burst-size: Sets the EBS in bytes. The value range for peak-information-rate is 0 to 1000000000. If the PIR is configured, the default EBS is the product of 62.5 and the PIR.

queue-length queue-length: Sets the maximum number of packets allowed in the queue. The default is 50. The value range for queue-length is 1 to 1024.

Usage guidelines

A QoS policy that uses a behavior configured with GTS can be applied only to the outbound direction of an interface.

A QoS policy that uses a behavior configured with GTS overwrites the qos gts command on the interface, if both are configured.

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

To use two rates for traffic shaping, configure the gts command with the pir peak-information-rate option. To use one rate for traffic shaping, configure the gts command without the pir peak-information-rate option.

Examples

# Configure a GTS action in absolute value in traffic behavior database. The GTS parameters are as follows: CIR is 200 kbps, CBS is 51200 bytes, EBS is 0, and the maximum queue length is 100.

A QoS policy that uses a behavior configured with percentage-based GTS overwrites the qos gts command on the interface, if both configured.

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

Examples

# Configure a GTS action in percentage in traffic behavior database. The GTS parameters are as follows: CIR is 50 and CBS is 200 ms.

<Sysname> system-view

[Sysname] traffic behavior database

[Sysname-behavior-database] gts percent cir 50 cbs 200

Views

Traffic behavior view

Predefined user roles

network-admin

Parameters

policy-name: Specifies a policy by its name, a string of 1 to 31 characters. If the policy does not exist, it is automatically created.

Usage guidelines

After you nest a child policy in a behavior of a parent policy, the system performs the following operations:

· Performs the associated behavior defined in the parent policy for a class of traffic.

· Uses the child policy to further classify the class of traffic and performs the behaviors defined in the child policy.

When you nest QoS policies, follow these guidelines:

· A parent policy can nest up to two layers of child policies. This child policy cannot be the parent policy itself.

· You can nest only one child policy at one layer of a behavior.

· To configure CBQ in the child policy successfully, configure GTS in the parent policy. Make sure the configured GTS bandwidth is greater than CBQ bandwidth configured in the child policy.

· If GTS bandwidth is set in percentage in the parent policy, you must set CBQ bandwidth in percentage in the child policy. If GTS bandwidth is set as an absolute value in the parent policy, you can set CBQ bandwidth in either format in the child policy.

· A child policy cannot contain GTS actions.

· Policy nesting is available for IPv4 and IPv6 packets.

· To delete the child policy after you apply the parent policy to an interface, first remove the child policy from the parent policy.

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.

The undo classifier default-class command performs the following operations:

· Deletes the existing class-behavior association for the system-defined class default-class.

· Associates the system-defined class default-class with the system-defined behavior be.

qos apply policy (interface view, PVC view, control plane view, PW view)

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

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

Syntax

qos apply policy policy-name { inbound | outbound } [ preorder preorder-value ]

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

Default

No QoS policy is applied.

Views

Control plane view

Cross-connect PW view/VSI LDP PW view/VSI static PW view

Interface view

PVC 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 incoming traffic. This keyword is not supported in PW view.

outbound: Applies the QoS policy to outgoing traffic. This keyword is not supported in control plane view.

preorder preorder-value: Specifies the order in which QoS policies applied to the same direction of an interface are executed. The greater the value, the higher the priority. The value for the preorder-value argument can only be 1. A QoS policy configured with this option is executed before a QoS policy that is not configured with this option. QoS policies applied in the same direction cannot be configured with the same order value.

Usage guidelines

When you apply a QoS policy to an interface, PVC, or PW, follow these rules:

· The bandwidth assigned to AF and EF queues in the QoS policy must be smaller than the available bandwidth of the interface, PVC, or PW. Otherwise, the QoS policy cannot be successfully applied to the interface, PVC, or PW.

· If you modify the available bandwidth of the interface, PVC, or PW to be smaller than the bandwidth for AF and EF queues, the applied QoS policy is removed.

· An inbound QoS policy cannot contain a GTS action or any of these queuing actions: queue ef, queue af, or queue wfq.

If the action is redirecting traffic to a security card, the QoS policy must be applied in enhanced mode.

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

The preorder preorder-value option is supported only in interface view.

Examples

# Apply QoS policy USER1 to the incoming traffic of GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] qos apply policy USER1 inbound

Parameters

number: Specifies a tunnel interface by its number in the range of 0 to 10239.

ipv4-address: Specifies the spoke's private IPv4 address of a hub-spoke tunnel.

ipv6-address: Specifies the spoke's private IPv6 address of a hub-spoke tunnel.

outbound: Specifies the QoS policies applied to the outbound direction. If you do not specify this keyword, the command clears for both the QoS policies applied to the inbound direction and the QoS policies applied to the outbound direction.

Usage guidelines

If you do not specify a spoke's private IP address of a hub-spoke tunnel, this command clears the QoS policy statistics for all hub-spoke tunnels on a tunnel interface. For information about hub-spoke tunnels, see ADVPN in Layer 3—IP Services Configuration Guide.

For configuration commands for tunnel interfaces, see tunnel commands in Layer 3—IP Services Command Reference.

The device only supports clearing the statistics for QoS policies applied to the outbound direction of tunnel interfaces.

QoS policy-based traffic rate statistics collection period commands

qos flow-interval

Use qos flow-interval to set the QoS policy-based traffic rate statistics collection period for an interface.

Use undo qos flow-interval to restore the default.

Syntax

qos flow-interval interval

undo qos flow-interval

Default

The QoS policy-based traffic rate statistics collection period is 5 minutes on an interface.

Views

Interface view

Predefined user roles

network-admin

Parameters

interval: Sets the QoS policy-based traffic rate statistics collection period in minutes. The value range for this argument is 1 to 10.

Usage guidelines

You can enable collection of per-class traffic statistics over a period of time, including the average forwarding rate and drop rate. For example, if you set the statistics collection period to 10 minutes, the system performs the following operations:

· Collects traffic statistics for the most recent 10 minutes.

· Refreshes the statistics every 10/5 minutes, 2 minutes.

The traffic rate statistics collection period of a subinterface is the same as the period configured on the main interface.

Examples

# Set the QoS policy-based traffic rate statistics collection period to 10 minutes on GigabitEthernet 1/0/1.

<Sysname> system-view

Parameters

carl-index: Specifies a CAR list by its number in the range of 1 to 199.

dscp dscp-list: Specifies a list of DSCP values. A DSCP value can be a number from 0 to 63 or any of the following keywords af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs1, cs2, cs3, cs4, cs5, cs6, cs7, default, or ef. You can configure up to eight DSCP values in one command line. If the same DSCP value is specified multiple times, the system considers the values to be one value. If a packet matches one of the defined DSCP values, it matches the if-match clause.

mac mac-address: Specifies a MAC address in hexadecimal format.

mpls-exp mpls-exp-value: Specifies an MPLS EXP value in the range of 0 to 7. You can configure up to eight MPLS EXP values in one command line. If the same MPLS EXP value is specified multiple times, the system considers the values to be one value. If a packet matches one of the defined MPLS EXP values, it matches the if-match clause.

precedence precedence: Specifies a precedence value in the range of 0 to 7. You can configure up to eight IP precedence values in one command line. If the same IP precedence value is specified multiple times, the system considers the values to be one value. If a packet matches one of the defined IP precedence values, it matches the if-match clause.

destination-ip-address: Configures a destination IP address-based CAR list.

source-ip-address: Configures a source IP address-based CAR list.

range start-ip-address to end-ip-address: Specifies an IP address range by the start address and end address. The value for end-ip-address must be greater than the value for start-ip-address. The maximum number of IP addresses that an IP address range can accommodate is 1024.

subnet ip-address mask-length: Specifies a subnet by the IP subnet address and IP subnet address mask length. The value range for mask-length is 22 to 31.

per-address: Performs per-IP address rate limiting within the network segment. When this keyword is specified, the CIR is dedicated bandwidth for each IP address and is not shared by any other IP address. If you do not specify this keyword, the following events occur:

· Rate limiting is performed for the entire network segment.

· All of the CIR is allocated among all IP addresses in proportion to the traffic load of each IP address.

shared-bandwidth: Specifies that traffic of all IP addresses within the network segment shares the remaining bandwidth (the CIR). If you specify this keyword, all of the CIR is allocated evenly among all IP addresses with traffic load.

Usage guidelines

You can create a CAR list based on IP precedence, MAC address, MPLS EXP, DSCP, or IP network segment.

If you execute this command multiple times for the same CAR list, the most recent configuration takes effect. If you execute this command multiple times for different CAR lists, multiple CAR lists are created.

To perform rate limiting for a single IP address, use the qos car acl command in interface view.

Examples

# Apply CAR list 1 to the outbound direction of GigabitEthernet 1/0/1 to meet the following requirements:

· The rate of each host on the subnet 1.1.1.0/24 is limited to 512 kbps.

Predefined user roles

network-admin

Parameters

percent: Specifies the percentage of available bandwidth to be reserved. The value range for this argument is 1 to 100.

Usage guidelines

The maximum reserved bandwidth is set on a per-interface or per-PVC basis. It decides the maximum bandwidth assignable for the QoS queues on an interface or PVC. It is typically set no greater than 80% of available bandwidth, considering the bandwidth for control traffic and Layer 2 frame headers.

Use the default maximum reserved bandwidth setting in most situations. If you adjust the setting, make sure the Layer 2 frame header plus the data traffic is under the maximum available bandwidth of the interface.

The maximum available bandwidth of an interface can be set by using the bandwidth command. For more information about this command, see Interface Command Reference.

If you execute the qos reserved-bandwidth pct command multiple times, the most recent configuration takes effect.

Examples

# Set the maximum reserved bandwidth to 70% of available bandwidth on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

Use undo queue af to restore the default.

Syntax

queue af bandwidth { bandwidth | pct percentage | remaining-pct remaining-percentage }

undo queue af

Default

AF is not configured.

network-admin

Parameters

bandwidth: Specifies the bandwidth in kbps. The value range for this argument is 8 to 10000000.

pct percentage: Specifies the percentage of the available bandwidth, in the range of 1 to 100.

remaining-pct remaining-percentage: Specifies the percentage of the remaining bandwidth, in the range of 1 to 100.

Usage guidelines

To associate the traffic behavior configured with the queue af command with a class in a policy, you must follow these requirements:

· The total bandwidth assigned to AF and EF queues in a policy cannot exceed the maximum available bandwidth of the interface where the policy is applied.

· The total percentage of bandwidth assigned to AF and EF in a policy cannot exceed 100.

· The bandwidth assigned to AF and EF in a policy must use the same form, either as an absolute bandwidth value or as a percentage.

If you execute the queue af command multiple times, the most recent configuration takes effect.

Examples

# Configure AF in traffic behavior database and assign the minimum guaranteed bandwidth 200 kbps to it.

Parameters

bandwidth: Specifies the bandwidth in kbps. The value range for this argument is 8 to 10000000.

cbs burst: Sets the CBS in bytes. The value range for this argument is 32 to 1000000000. The default is bandwidth × 25.

pct percentage: Specifies the percentage of the available bandwidth, in the range of 1 to 100.

cbs-ratio ratio: Sets the allowed burst ratio in the range of 25 to 500. This default is 25.

Usage guidelines

You cannot use this command in conjunction with the queue af or queue-length command in the same traffic behavior.

In a policy, the default class cannot be associated with the traffic behavior that has the queue ef command.

The total bandwidth assigned to AF and EF in a policy cannot exceed the maximum available bandwidth of the interface where the policy is applied.

The total percentage of the maximum available bandwidth assigned to AF and EF in a policy cannot exceed 100.

The bandwidths assigned to AF and EF in a policy must have the same type, bandwidth or percentage.

After the queue ef bandwidth pct percentage [ cbs-ratio ratio ] command is used, CBS equals (Interface available bandwidth × percentage × ratio)/100/1000.

After the queue ef bandwidth bandwidth [ cbs burst ] command is used, CBS equals burst. If the burst argument is not specified, CBS equals bandwidth × 25.

If you execute the queue ef command multiple times, the most recent configuration takes effect.

Parameters

exponent: Specifies the exponent for average queue length calculation, in the range of 1 to 16.

Usage guidelines

Before configuring this command, enable WRED on the interface or PVC with the qos wred enable command.

If you execute the qos wred weighting-constant command multiple times, the most recent configuration takes effect.

Examples

# Set the exponent for the average queue size calculation to 6 on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

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.

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

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 GigabitEthernet 1/0/1 to get the IP precedence and local QoS ID by looking up routes based on source IP address.
