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.
¡ 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.
· 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

Parameters
cir percent 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 actual CBS value is cbs-time × the actual CIR value. The value range for the cbs-time argument is 50 to 2000. The default CBS is the product of 62.5 and the CIR.
ebs ebs-time: Specifies the EBS in milliseconds. The actual EBS value is ebs-time × the actual CIR value. The value range for the ebs-time argument is 0 to 2000. The default EBS is 0.
pir percent pir-percent: Specifies the PIR in percentage, in the range of 1 to 100. The PIR value must be greater than or equal to the CIR value.
green action: Specifies the action to take on packets that conform to the CIR. The default is pass.
red action: Specifies the action to take on packets that conform to neither CIR nor PIR. The default is discard.
yellow action: Specifies the action to take on packets that conform to the PIR but not to the CIR. The default 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 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. Alternatively, you can specify the new-dscp argument with af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs1, cs2, cs3, cs4, cs5, cs6, cs7, default, or ef.
· remark-mpls-exp-pass new-exp: Sets the EXP field value of the MPLS packet to new-exp and permits the packet to pass through. The new-exp argument is in the range of 0 to 7.
· remark-prec-pass new-precedence: Sets the IP precedence of the packet to new-precedence and permits the packet to pass through. The new-precedence argument is in the range of 0 to 7.
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 (for example, tunnel interface and Layer 3 aggregate 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 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.

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.
· 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.
Examples
# Nest child policy child in traffic behavior database of 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.
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 (interface view, control plane view, control-plane management view)
Use qos apply policy to apply a QoS policy to an interface or control plane.
Use undo qos apply policy to remove an applied QoS policy.
Syntax
qos apply policy policy-name { inbound | outbound }
undo qos apply policy policy-name { inbound | outbound }
Default
No QoS policy is applied.
Views

context-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.
outbound: Applies the QoS policy to outgoing traffic.
Usage guidelines
When you apply a QoS policy to an interface, 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. Otherwise, the QoS policy cannot be successfully applied to the interface.
· If you modify the available bandwidth of the interface to be smaller than the bandwidth for AF and EF queues, the applied QoS policy is removed.
A QoS policy configured with CBQ is not supported in control plane view or control-plane management 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

context-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.

· remark-prec-pass new-precedence: Remarks the packet with a new IP precedence and permits the packet to pass through. The new-precedence argument is in the range of 0 to 7.
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.
Examples
# Perform CAR for all packets in the outbound direction of GigabitEthernet 1/0/1. 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.

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, 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.

Parameters
pql pql-index: Specifies a PQ list by its number in the range of 1 to 16.
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.

network-admin
context-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.

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.

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.
