Usage guidelines

In a traffic class with the logical OR operator, you can configure multiple if-match commands for any of the available match criteria.

When you configure a match criterion that can have multiple values in one if-match command, follow these restrictions and guidelines:

· You can specify up to eight values for any of the following match criteria in one if-match command:

¡ 802.1p priority.

¡ DSCP.

¡ IP precedence.

¡ 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.

To use an ACL match criterion, the ACL must already exist.

· If the ACL contains deny rules, the if-match command is ignored and the matching process continues.

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. 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.

Predefined user roles

network-admin

Parameters

cir cir-percent: Specifies the CIR in percentage, in the range of 1 to 100. The actual CIR value is cir-percent × interface bandwidth.

cbs cbs-time: Specifies the CBS in milliseconds. The default cbs-time is 500 milliseconds. The actual CBS value is cbs-time × the actual CIR value. The value range for cbs-time is 50 to 2000. The default value is 500.

ebs ebs-time: Specifies the EBS in milliseconds. The default ebs-time is 0 milliseconds. The actual EBS value is ebs-time × the actual CIR value. The value range for ebs-time is 0 to 2000. The default value is 0.

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

Usage guidelines

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

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.

Parameters

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

slot slot-number: Redirects traffic to a card specified by its slot number.

srv6-policy endpoint color [ { sid | vpnsid } sid ]: Redirects traffic to an SRv6 TE policy. The endpoint argument represents the endpoint IPv6 address of the SRv6 TE policy. The color argument represents the color attribute value of the SRv6 TE policy, in the range of 0 to 4294967295. The sid sid argument represents the SRv6 SID (an IPv6 address) of the egress node. Packets continue to be forwarded in the public network after they are forwarded through the SRv6 TE policy. The vpnsid sid argument represents the SRv6 SID (an IPv6 address) of the egress node. Packets continue to be forwarded in the private network after they are forwarded through the SRv6 TE policy. The device adds the SRv6 SID to the SRH header and places it after the SID list. After the packets are forwarded to the egress node, the egress node takes the forwarding action based on the SRv6 SID.

Usage guidelines

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

Make sure the specified SRv6 SID is correct. This value in packets does not indicate the public or private network attribute. The destination node forwards the packets according to the local SID table.

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.

# Nest child policy child in traffic behavior database of the parent policy.

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.

Related commands

mode channel-bandwidth

Use mode channel-bandwidth to set the channelized bandwidth for a subinterface.

Use undo mode channel-bandwidth to restore the default.

Syntax

mode channel-bandwidth bandwidth-value

undo mode channel-bandwidth

Default

The channelized bandwidth is not set for a subinterface.

Views

Subinterface view

Predefined user roles

network-admin

Parameters

bandwidth-value: Specifies the channelized bandwidth in kbps. The value range for this argument is 30 to 9500000.

Usage guidelines

By default, all subinterfaces of a main interface share and contend for the bandwidth of the main interface. Subinterfaces that carry key services cannot be guaranteed enough bandwidth. This feature allows subinterfaces of a physical interface or aggregate interface to exclusively use the specified amount of bandwidth.

Before configuring the channelized bandwidth for a Layer 3 aggregate subinterface, you must execute the bandwidth command on the aggregate interface.

The total channelized bandwidth of subinterfaces cannot exceed the actual bandwidth of the main interface plus 1 Mbps. The channelized bandwidth takes effect only in the outbound direction.

Examples

# Set the channelized bandwidth to 100 kbps for GigabitEthernet1/0/1.1.

Usage guidelines

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

You can configure multiple qos car commands on an interface to define multiple CAR policies. These CAR policies are executed in their configuration order.

When you reference an ACL, follow these restrictions and guidelines:

· If the ACL does not exist or contains no rules, the ACL is not used for traffic policing.

· If the vpn-instance vpn-instance option is specified in a rule, the rule applies only to VPN packets. If the vpn-instance vpn-instance option is not specified in a rule, the rule applies only to non-VPN packets.

Examples

# Perform CAR for all packets in the outbound direction of GigabitEthernet 0/0/1. The CAR parameters are as follows:

· CIR is 200 kbps.

· CBS is 5120 bytes.

· EBS is 0.

· Conforming packets are transmitted.

· Excess packets are set with an IP precedence of 0 and transmitted.

Usage guidelines

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

You can configure multiple qos car percent commands on an interface to define multiple CAR policies. These CAR policies are executed in their configuration order.

When you reference an ACL, follow these restrictions and guidelines:

· If the ACL does not exist or contains no rules, the ACL is not used for traffic policing.

Predefined user roles

network-admin

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.

subnet ip-address mask-length: Specifies a subnet by the IP subnet address and IP subnet address mask length.

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 0/0/1 to meet the following requirements:

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

· Traffic of IP addresses in the subnet does not share the remaining bandwidth.

Usage guidelines

This command allows the device to include a 24-byte physical layer header in calculating the packet length for rate limiting. As a best practice, configure this command in scenarios where packets are small and precise rate limiting is required. To save computing resources, do not configure this command if the device processes large packets.

This command takes effect only on Layer 3 Ethernet interfaces and Layer 3 aggregate interfaces.

Usage guidelines

If you execute this command multiple times on an interface, the most recent configuration takes effect.

Multiple match criteria can be configured for a PQ list. When a packet arrives, it is examined against match criteria in their configuration order.

· If a match is found, the packet is assigned to the corresponding queue, and the matching process ends.

· If no match is found, the packet is assigned to the default queue.

You must configure the rate limit for the queuing feature to take effect on the following interfaces:

· Tunnel interfaces.

· Subinterfaces.

· Layer 3 aggregate interfaces.

· HDLC link bundle interfaces.

· VT and dialer interfaces configured with PPPoE.

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 basis. It decides the maximum bandwidth assignable for the QoS queues on an interface. 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 0/0/1.

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.

queue ef

Use queue ef to configure expedited forwarding (EF) and assign its maximum bandwidth.

Use undo queue ef to restore the default.

Syntax

queue ef bandwidth { bandwidth [ cbs burst ] | pct percentage [ cbs-ratio ratio ] }

undo queue ef

Default

EF is not configured.

Views

Predefined user roles

network-admin

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.

Examples

# Configure EF in traffic behavior database, with the maximum bandwidth as 200 kbps and CBS as 5000 bytes.

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