Usage guidelines

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 single-tagged packets, you can use the service-vlan-id criterion to match them.

To configure multiple values for a match criterion, perform the following tasks:

1. Set the logical operator to OR.

2. Configure multiple if-match commands for the match criterion.

For the customer-vlan-id and service-vlan-id match criteria, you can configure multiple values in one if-match command when the logical operator is OR or AND.

To delete multiple values configured in one if-match command, make sure the values specified in the undo if-match command are the same as the configured values. The order of the values can be different.

When you configure ACL-based match criteria for a traffic class, follow these restrictions and guidelines:

· If the ACL used as a match criterion does not exist, the QoS policy that uses the traffic class cannot be applied correctly.

· You can add two if-match statements that use the same ACL as the match criterion. In one statement, specify the ACL by its name. In the other statement, specify the ACL by its number.

· If the configured logical operator is AND for the traffic class, the actual logical operator for the rules in an ACL is OR.

Parameters

cir committed-information-rate: Specifies the committed information rate (CIR) in kbps, which specifies an average traffic rate. The value range for the committed-information-rate argument is 8 and 160000000 in multiples of 8.

cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes. The value range for the committed-burst-size argument is 512 and 256000000 in multiples 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. 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 the excess-burst-size argument is 0 and 256000000 in multiples of 512, and the default value is 512.

pir peak-information-rate: Specifies the peak information rate (PIR) in kbps. The value range for the peak-information-rate argument is 8 and 160000000 in multiples of 8.

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 conforms to neither CIR nor PIR. The default setting is discard.

yellow action: 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.

hierarchy-car hierarchy-car-name: Specifies a hierarchical CAR action to be used by its name.

mode: Specifies the collaborating mode of the hierarchical CAR action and the common CAR action:

· and: AND mode, the default mode in which the traffic rate of a flow is limited by both the common CAR applied to it and the total traffic rate defined with hierarchical CAR. For example, use common CAR actions to limit the rates of both Internet access flow 1 and flow 2 to 128 kbps, and use a hierarchical CAR action to limit their total traffic rate to 192 kbps. When flow 1 is not present, flow 2 can access the Internet at the maximum rate, 128 kbps. If both flows are present, each flow cannot exceed its own rate limit, and the total rate cannot exceed 192 kbps.

· or: OR mode, in which a flow can pass through at the rate equal to the common CAR applied to it or a higher rate if the total traffic rate of all flows does not exceed the hierarchical CAR. For example, use common CAR actions to limit the rates of both video flow 1 and flow 2 to 128 kbps, and then use a hierarchical CAR action to limit their total traffic rate to 512 kbps. As long as the rate of flow 1 does not exceed 128 kbps, flow 2 can pass at a rate up to 384 kbps.

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.

A QoS policy that uses the traffic behavior can be applied in either the inbound direction or outbound direction of an interface.

If you configure 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 as follows:

· 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.

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 with only 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.

You cannot change the position of an existing traffic class in a QoS policy.

Examples

# Associate traffic class database with traffic behavior test in QoS policy user1.

<Sysname> system-view

[Sysname] qos policy user1

queue

Use queue to configure the drop-related parameters for a queue in the queue-based WRED table.

Use undo queue to restore the default.

Syntax

queue queue-id [ drop-level drop-level ] low-limit low-limit high-limit high-limit [ discard-probability discard-prob ]

undo queue { queue-id | all }

Default

After a WRED table is created, the lower limit is 100, the upper limit is 1000, and the drop probability is 10%.

Views

WRED table view

Predefined user roles

network-admin

Parameters

queue-id: Specifies a queue by its ID in the range of 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, in the range of 0 to 16000.

high-limit high-limit: Specifies the upper limit for the average queue length. The high-limit argument is in the range of 0 to 16000 and must be greater than the low-limit argument.

discard-probability discard-prob: Specifies the drop probability in percentage, in the range of 0 to 100.

Usage guidelines

When the average queue size is smaller than the lower limit, no packet is dropped. When the average queue size is between the lower limit and the upper limit, packets are dropped based on the user-configured drop probability. When the average queue size exceeds the upper limit, subsequent packets are dropped.

Examples

# In queue-based WRED table queue-table1, configure drop-related parameters for packets in queue 1 as follows:

· 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 in the range of 0 to 7.

Usage guidelines

When both the receiver and sender support ECN, the device can notify the peer end of the congestion status by identifying and setting the ECN flag. ECN avoids deteriorating congestion.

Examples

# In WRED table queue-table1, enable ECN for queue 1.

Predefined user roles

network-admin

Parameters

queue-id: Specifies a queue by its ID.

weighting-constant exponent: Specifies the WRED exponent for average queue length calculation, in the range of 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 set 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.

Predefined user roles

network-admin

Parameters

agg-car-name: Specifies the name of the aggregate CAR action to be used. This argument must start with a letter, and is a case-sensitive string of 1 to 31 characters.

hierarchy-car-name: Specifies the name of the hierarchical CAR action to be used. This argument must start with a letter, and is a case-sensitive string of 1 to 31 characters.

mode: Specifies a collaborating mode between the hierarchical CAR action and the aggregate CAR action, which can be AND (the default) or OR. If you do not specify a collaborating mode, the AND mode applies.

· and: AND mode, in which the traffic rate of a flow is limited by both the aggregate CAR applied to it and the total traffic rate defined with hierarchical CAR. For example, use aggregate CAR actions to limit the rates of both Internet access flow 1 and flow 2 to 128 kbps, and use a hierarchical CAR action to limit their total traffic rate to 192 kbps. When flow 1 is not present, flow 2 can access the Internet at the maximum rate, 128 kbps. If both flows are present, each flow cannot exceed its own rate limit, and the total rate cannot exceed 192 kbps.

· or: OR mode, in which a flow can pass through at the rate equal to the aggregate CAR applied to it or a higher rate if the total traffic rate of all flows does not exceed the hierarchical CAR. For example, use aggregate CAR actions to limit the rates of both video flow 1 and flow 2 to 128 kbps, and then use a hierarchical CAR action to limit their total traffic rate to 512 kbps. As long as the rate of flow 1 does not exceed 128 kbps, flow 2 can pass at a rate as high as 384 kbps.

Examples

# Use aggregate CAR action aggcar-1 in traffic behavior be1.

<Sysname> system-view

[Sysname] traffic behavior be1

[Sysname-behavior-be1] car name aggcar-1

# Configure traffic behavior be1 to use aggregate CAR action aggcar-1 and hierarchical CAR action hcar, with the collaborating mode as or.
