Usage guidelines

Only the following match criteria are supported to match MPLS packets:

· customer-dot1p.

· customer-vlan-id.

· destination-mac.

· service-dot1p.

· source-mac.

In a traffic class with the logical OR operator, you can configure multiple if-match commands for any of the available match criteria. You can also configure multiple values in one if-match command for any of the following available match criteria:

· 802.1p priority.

· Control plane protocol.

· DSCP.

· IP precedence.

· VLAN ID.

To delete a criterion that has multiple values, make sure the specified values in the undo if-match command are the same as those specified in the if-match command. The order of values can be different.

In a traffic class with the logical AND operator, if you configure multiple values for a match criterion, the traffic behavior associated with the traffic class cannot be applied correctly.

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 traffic class cannot be applied to hardware.

· 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.

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

For the control plane protocol match criterion, you can use the display qos policy control-plane pre-defined command to display predefined control plane protocols.

If a traffic class includes the control-plane protocol or control-plane protocol-group match criterion, the QoS policy that uses this traffic class can be applied only to a control plane.

Parameters

cir committed-information-rate: Specifies the committed information rate (CIR) in kbps, which is an average traffic rate. The value range for committed-information-rate is 8 to 160000000. The value must be an integral multiple 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 to 256000000. The value must be an integral multiple 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 to 256000000. The value must be an integral multiple of 512.

pir peak-information-rate: Specifies the peak information rate (PIR) in kbps. The value range for the peak-information-rate argument is 8 to 160000000. The value must be an integral multiple 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 the packet that conforms to neither the 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.

hierarchy-car-name: Specifies the name of the used hierarchical CAR action. This argument is not supported in the current software version.

mode: Specifies the collaborating mode of the hierarchical CAR action and the common CAR action. This keyword is not supported in the current software version.

· and: Specifies the AND mode (the default mode). In this mode, 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, you can perform the following configurations:

¡ Use common CAR actions to limit the rate of Internet access flow 1 and that of flow 2 to 128 kbps respectively.

¡ 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: Specifies the OR mode. In this mode, a flow can perform one of the following tasks:

¡ Pass through at the rate equal to the common CAR applied to it.

¡ Pass through at a higher rate if the total traffic rate of all flows does not exceed the hierarchical CAR.

For example, you can perform the following configurations:

¡ Use generic CAR actions to limit the rate of video flow 1 and that of flow 2 to 128 kbps respectively.

¡ 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 CAR action can be applied in the inbound 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 conforming packets, and mark excess packets with DSCP value 0 and transmit them.

local-id-value: Specifies the local QoS ID to be marked for packets. The value range for this argument is 1 to 4095.

Usage guidelines

Marking a local QoS ID for traffic of multiple classes combines these traffic classes into one new class indicated by the local QoS ID. You can configure a traffic behavior for this new class to implement two levels of actions on these traffic classes.

A local QoS ID marking action can be applied only to incoming traffic.

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

Use remark service-vlan-id to configure an SVLAN marking action in a traffic behavior.

Use undo remark service-vlan-id to delete the action.

Syntax

behavior-name: Specifies a traffic behavior by its name, a case-sensitive string of 1 to 31 characters.

insert-before before-classifier-name: Inserts a new class before an existing class. The before-classifier-name argument specifies an existing 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 class is placed at the end of the QoS policy.

mode dcbx: Specifies that the class-behavior association applies only to DCBX. For more information about DCBX, see Layer 2—LAN Switching Configuration Guide.

Usage guidelines

A traffic class can be associated only with one traffic behavior in a QoS policy.

Parameters

table table-name: Specifies the name of the WRED table.

Usage guidelines

You cannot delete a WRED table applied to an interface. To delete it, first remove it from the interface.

Examples

# Create a queue-based WRED table named queue-table1.

queue

Use queue to configure the drop-related parameters for a queue in a 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

The low-limit argument is 100, the high-limit argument is 1000, and the discard-prob argument is 10.

Parameters

queue-id: Specifies a queue by its ID, which can be a number in the range of 0 to 7 or a keyword in Table 19.

drop-level drop-level: Specifies a drop level. 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 16383.

high-limit high-limit: Specifies the upper limit for the average queue length, in the range of 0 to 16383. The value for the high-limit argument must be greater than the value for 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 threshold, no packet is dropped. When the average queue size is between the lower threshold and the upper threshold, the packets are dropped randomly according to the configured drop probability. The longer the queue, the higher the drop probability. When the average queue size exceeds the upper threshold, all 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.

· The drop probability is 30%.

Parameters

queue-id: Specifies a queue by its ID, which can be a number in the range of 0 to 7 or a keyword in Table 19.

Usage guidelines

When both the receiver and sender support ECN, the switch 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.

queue weighting-constant

Use queue weighting-constant to specify an exponent for average queue length calculation for a queue.

Use undo queue weighting-constant to restore the default.

Syntax

queue queue-id weighting-constant exponent

undo queue queue-id weighting-constant

Default

The exponent for average queue length calculation is 9.

Parameters

queue-id: Specifies a queue by its ID, which can be a number in the range of 0 to 7 or a keyword in Table 19.

weighting-constant exponent: Specifies the WRED exponent for average queue length calculation, in the range of 1 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 configured 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.

<Sysname> system-view

[Sysname] qos wred queue table queue-table1

[Sysname-wred-table-queue-table1] queue 1 weighting-constant 12

Parameters

car-name: Specifies the name of the global CAR action, a case-sensitive string of 1 to 31 characters. This argument must start with a letter.

aggregative: Specifies the global CAR action as an aggregate CAR action.

hierarchy: Specifies the global CAR action as a hierarchical CAR action. This keyword is not supported in the current software version.

cir committed-information-rate: Specifies the CIR in the range of 8 to 160000000 kbps. The value must be an integral multiple of 8.

cbs committed-burst-size: Specifies the CBS in bytes. The value range for the committed-burst-size argument is 512 to 256000000. The value must be an integral multiple 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 EBS in the range of 0 to 256000000 bytes. The value must be an integral multiple of 512. The default value is 512.

pir peak-information-rate: Specifies the PIR in the range of 8 to 160000000 kbps. The value must be an integral multiple 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. 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.

Usage guidelines

An aggregate CAR action takes effect only after it is applied to an interface or used in a QoS policy.

An aggregate CAR action is supported only in the inbound direction.

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

Examples

# Configure the aggregate CAR action aggcar-1 as follows:

· The CIR is 25600 kbps.

· The CBS is 512000 bytes.

· Red packets are dropped.
