Parameters

match-criteria: Specifies a match criterion. Table 2 shows the available match criteria.

Table 2 Available match criteria

Option	Description
acl [ ipv6 \| mac ] { acl-number \| name acl-name }	Matches an ACL. The value range for the acl-number argument is as follows: · 2000 to 3999 for IPv4 ACLs. · 2000 to 3999 for IPv6 ACLs. · 4000 to 4999 for Layer 2 MAC ACLs. The acl-name argument is a case-insensitive string of 1 to 63 characters, which must start with an English letter. To avoid confusion, make sure the argument is not all. If no VPN instance is specified in an ACL rule, the ACL rule takes effect on both non-VPN packets and VPN packets.
any	Matches all packets.
customer-dot1p dot1p-value&<1-8>	Matches 802.1p priority values in inner VLAN tags of double-tagged packets. The dot1p-value&<1-8> argument specifies a space-separated list of up to eight 802.1p priority values. The value range for the dot1p-value argument is 0 to 7.
customer-vlan-id vlan-id-list	Matches VLAN IDs in inner VLAN tags of double-tagged packets. The vlan-id-list argument specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN or a range of VLANs in the form of vlan-id1 to vlan-id2. The value for vlan-id2 must be greater than or equal to the value for vlan-id1. The value range for the vlan-id argument is 1 to 4094.
destination-mac mac-address [ mac-address-mask ]	Matches a destination MAC address. This option takes effect only on Ethernet interfaces.
dscp dscp-value&<1-8>	Matches DSCP values. The dscp-value&<1-8> argument specifies a space-separated list of up to eight DSCP values. The value range for the dscp-value argument is 0 to 63 or keywords shown in Table 4.
forwarding-layer { bridge \| route }	Matches Layer 2 forwarded packets or Layer 3 forwarded packets. · bridge—Matches Layer 2 forwarded packets. · route—Matches Layer 3 forwarded packets.
ip-precedence ip-precedence-value&<1-8>	Matches IP precedence values. The ip-precedence-value&<1-8> argument specifies a space-separated list of up to eight IP precedence values. The value range for the ip-precedence-value argument is 0 to 7.
protocol protocol-name	Matches a protocol. The protocol-name argument can be ip or ipv6.
service-dot1p dot1p-value&<1-8>	Matches 802.1p priority values in outer VLAN tags. The dot1p-value&<1-8> argument specifies a space-separated list of up to eight 802.1p priority values. The value range for the dot1p-value argument is 0 to 7.
service-vlan-id vlan-id-list	Matches VLAN IDs in outer VLAN tags. The vlan-id-list argument specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN or a range of VLANs in the form of vlan-id1 to vlan-id2. The value for vlan-id2 must be greater than or equal to the value for vlan-id1. The value range for the vlan-id argument is 1 to 4094. You can use this option to match single-tagged packets.
source-mac mac-address	Matches a source MAC address. This option takes effect only on Ethernet interfaces.
tunnel-id tunnel-id	Matches a tunnel ID. A QoS policy containing this option can be applied only to the inbound direction.

‌

Usage guidelines

If a Layer 2 ACL rule contains a MAC address match criterion, the ACL rule cannot match IPv6 packets in a QoS policy applied to the outbound direction.

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.

¡ 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.

· 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.

For a QoS policy to match IPv6 packets, you must specify IPv6 packet match criteria (for example, configure a rule to match the IPv6 protocol type) in the corresponding traffic classes.

For a QoS policy to match MPLS packets on an LSCM1GT48SC0 card, you must specify MPLS packet match criteria (for example, configure an ACL to match the MPLS protocol type) in the corresponding traffic classes.

mdc-admin

Parameters

cir committed-information-rate: Specifies the committed information rate (CIR) in the range of 16 to 100000000, which must be a multiple of 8.

cbs committee-burst-size: Specifies the committed burst size (CBS) in bytes. The value range for committed-burst-size is 512 to 67092480, 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 67092480 is converted to 67092480.

ebs excess-burst-size: Specifies the excess burst size (EBS) in the range of 512 to 67092480 bytes. The value must be an integral multiple of 512.

pir peak-information-rate: Specifies the peak information rate (PIR) in the range of 16 to 100000000 kbps, in increments of 8. The PIR and CIR must be configured in the same measurement unit.

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.

Usage guidelines

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

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 256 kbps, CBS to 51200 bytes, and EBS to 0.

Predefined user roles

network-admin

mdc-admin

Parameters

cpu: Redirects traffic to the CPU.

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

next-hop: Redirects traffic to a next hop. For successful traffic redirection, make sure the next hop IP address is reachable. If both primary and secondary next hop IP addresses are specified, make sure a minimum of one IP address is reachable. The redirection feature periodically looks up the routing table to verify the reachability of next hop IP addresses. If track entries are specified, the redirection feature verifies the reachability of the next hop IP addresses based on the Track detection result. If both primary and secondary next hop IP addresses are unreachable, traffic redirection to a next hop does not take effect.

ipv4-add1: Specifies the primary next hop IPv4 address. If traffic fails to be redirected to this IPv4 address, the traffic is redirected to the secondary IPv4 address.

ipv4-add2: Specifies the secondary next hop IPv4 address.

ipv6-add1: Specifies the primary next hop IPv6 address. If traffic fails to be redirected to this IPv6 address, the traffic is redirected to the secondary IPv6 address.

ipv6-add2: Specifies the secondary next hop IPv6 address.

track track-entry-number: Specifies a track entry by its ID in the range of 1 to 1024. Different track entries can be specified for primary and secondary IP addresses. By specifying track entries, you can associate traffic redirection with detection modules, such as NQA and BFD (see High Availability Configuration Guide).

fail-action: Specifies the action to take on packets if the next hop IP address does not exist. Without this parameter configured, the device discards packets if the next hop IP address does not exist.

discard: Discards packets.

forward: Forwards packets.

Usage guidelines

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

A traffic redirecting action takes effect only when the QoS policy is applied to the inbound direction.

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.

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.

<Sysname> system-view

Parameters

table table-name: Specifies a name for the WRED table, a case-sensitive string of 1 to 32 characters.

Usage guidelines

You cannot delete a WRED table in use. To delete it, first remove it from the specified interface.

You can use the display qos wred table command to display the default WRED table, which cannot be modified or deleted.

Examples

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

queue (WRED table view)

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 [ drop-level drop-level ] | all }

Default

The lower limit is 100, the upper limit is 1000, and the drop probability is 10%.

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 value range for low-limit is 0 to 16383. The value is in 288 bytes on the SC modules prefixed with LSCM2, SD modules, and SE modules and in 256 bytes on LSCM1GT48SC0 cards.

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. The value is in 288 bytes on the SC modules prefixed with LSCM2, SD modules, and SE modules and in 256 bytes on LSCM1GT48SC0 cards.

discard-probability discard-prob: Specifies the denominator for drop probability calculation. The greater the denominator, the greater 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 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 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.

cir committed-information-rate: Specifies the CIR in kbps, which is an average traffic rate. The value range for committed-information-rate is 16 to 100000000, in increments of 8.

ebs excess-burst-size: Specifies the excess burst size (EBS) in bytes. The value range for excess-burst-size is 0 to 67092480, in increments of 512. If the PIR is configured, the default EBS is the product of 62.5 and the PIR 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 67092480 is converted to 67092480.

pir peak-information-rate: Specifies the PIR in kbps. The value range for peak-information-rate is 16 to 100000000, in increments 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-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. This action takes effect only in the inbound direction on the SC modules prefixed with LSCM2 and SD modules.

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 used in a QoS policy. A QoS policy containing an aggregate CAR action can be applied to only one direction in the same view.

If the action for yellow packets is configured as discard, the action for red packets can only be configured as discard.

Examples

# Configure aggregate CAR action aggcar-1, where CIR is 25600, CBS is 512000, and red packets are dropped.

<Sysname> system-view

[Sysname] qos car aggcar-1 aggregative cir 25600 cbs 512000 red discard
