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.

¡ 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:

· If the ACL used as a match criterion does not exist, the traffic class cannot be applied to hardware.

· 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.

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, in increments of 8.

cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes. The value range for committed-burst-size is 512 to 256000000, in increments 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 that is greater than the product. A default value greater than 256000000 is converted to 256000000.

ebs excess-burst-size: Specifies the excess burst size (EBS) in bytes. The default value for excess-burst-size is 512. The value range for excess-burst-size is 0 to 256000000, in increments of 512.

pir peak-information-rate: Specifies the peak information rate (PIR) in kbps. The value range for peak-information-rate is 8 to 160000000, in increments 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 conform to neither 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.

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

· and: Specifies the AND mode (the default mode). In this mode, the traffic rate of a flow is limited by both the common CAR and the total traffic rate defined with hierarchical CAR.

· or: Specifies the OR mode. In this mode, a flow can perform one of the following operations:

¡ 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.

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 a traffic behavior configured with CAR can be applied in either the inbound direction or outbound direction of an interface.

If you execute 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:

· 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

mpls-exp: Applies 802.1p-to-EXP mappings to the first MPLS label.

Usage guidelines

This command applies 802.1p-to-EXP mappings to outgoing MPLS labels of a packet as follows:

· Applies 802.1p-to-EXP mappings to the first MPLS label and sets the EXP value in the second MPLS label to 0 if the packet comes from a private network and does not have MPLS labels.

· Applies 802.1p-to-EXP mappings to neither of the MPLS labels if the packet comes from the public network and has two MPLS labels.

Examples

# Map 802.1p priorities 4 and 5 to EXP value 1, and apply the 802.1p-to-EXP mappings to the first outgoing MPLS label of packets coming from a private network.

Parameters

queue queue-id: Shapes the packets in a queue specified by its ID. The value range for queue-id is 0 to 7.

cir committed-information-rate: Specifies the CIR in kbps. The committed-information-rate argument has the following value ranges: 8 to 1000000 for GE interfaces, 8 to 10000000 for 10-GE interfaces, 8 to 40000000 for 40-GE interfaces, 8 to 100000000 for 100-GE interfaces. The specified value must be an integral multiple of 8.

cbs committed-burst-size: Specifies the CBS in bytes. The value range for committed-burst-size is 512 to 16000000, in increments 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 that is greater than the product. A default value greater than 16000000 is converted to 16000000.

Usage guidelines

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

Predefined user roles

network-admin

mdc-admin

Parameters

all: Specifies all queues.

queue-id: Specifies a queue by its ID. The value range for this argument is 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. The for low-limit is 0 to 16383.

high-limit high-limit: Specifies the upper limit for the average queue length. The upper limit must be greater than the lower limit. The value range for high-limit is 0 to 16383.

discard-probability discard-prob: Specifies the denominator for drop probability calculation. The greater the denominator, the smaller the calculated drop probability. The value range for discard-prob is 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 at random. The longer the queue is, the higher the drop probability is. When the average queue size exceeds the upper threshold, 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. The value range for this argument is 0 to 7.

weighting-constant exponent: Specifies the WRED exponent for average queue length calculation. The value range for exponent is 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.

Parameters

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

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

hierarchy: Specifies the global CAR action as a hierarchical CAR action.

cir committed-information-rate: Specifies the CIR in kbps, which is an average traffic rate. The value range for committed-information-rate is 8 to 160000000, in increments of 8.

cbs committed-burst-size: Specifies the CBS in bytes. The value range for committed-burst-size is 512 to 256000000, in increments 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 that is greater than the product. A default value greater than 256000000 is converted to 256000000.

ebs excess-burst-size: Specifies the EBS in bytes. The value range for excess-burst-size is 0 to 256000000, in increments of 512. The default is 0.

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

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

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

A hierarchical CAR action takes effect only after it is used in a QoS policy.
