Parameters

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

Table 2 Available match criteria

Option	Description
acl [ ipv6 ] { acl-number \| name acl-name }	Matches an ACL. The value range for the acl-number argument is 2000 to 5999 for IPv4 ACLs, and 2000 to 3999 or 10000 to 42767 for IPv6 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 a QoS policy uses a user-defined ACL for traffic classification, the user-defined ACL takes effect only when the QoS policy is applied to the inbound direction. On an EB, EC2, or FD card operating in basic ACL mode, a QoS policy does not support a class that uses IPv6 ACLs or user-defined ACLs as match criteria.
control-plane protocol protocol-name&<1-8>	Matches control plane protocols. The protocol-name&<1-8> argument specifies a space-separated list of up to eight system-defined control plane protocols. For available system-defined control plane protocols, see Table 3. If a QoS policy that uses this match criterion in a class is to be applied to the control plane, the following restrictions apply: · The class cannot use any other match criterion. · The traffic behavior for the class can only have the rate limiting action configured by using the packet-rate command. If a QoS policy that uses this match criterion in a class is to be applied to the management interface control plane, the class cannot use any other match criterion, and the traffic behavior for the class can only have the traffic policing action (configured by using the car command).
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. This option is not supported in a global or VLAN QoS policy. On an EB, EC2, or FD card operating in basic ACL mode, a QoS policy does not support a class that uses the 802.1p priority values in inner VLAN tags as match criteria.
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. This option is not supported in a global or VLAN QoS policy. On an EB, EC2, or FD card operating in basic ACL mode, a QoS policy does not support a class that uses the VLAN IDs in inner VLAN tags as match criteria.
destination-mac mac-address	Matches a destination MAC address. On an EB, EC2, or FD card operating in basic ACL mode, suppose a QoS policy contains a class using a destination MAC address as a match criterion. · If the QoS policy is applied to the incoming traffic, the class does not take effect on IPv4 packets. · If the QoS policy is applied to the outgoing traffic, the class does not take effect on IPv4 or IPv6 packets. · If the QoS policy is applied to the incoming or outgoing traffic, the class does not take effect on ARP packets.
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 6.
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.
inbound-interface interface-type interface-number	Matches an input interface specified by its type and number. A QoS policy configured with this match criterion can be applied only to control planes. To apply the QoS policy successfully, make sure the input interface specified and the control plane to which you apply the QoS policy belong to the same card. When you use this match criterion for a class, you can only configure a traffic filtering (filter) or traffic policing (car) action in the behavior associated with the class.
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.
mpls-exp exp-value&<1-8>	Matches MPLS EXP values. The exp-value&<1-8> argument specifies a space-separated list of up to eight EXP values. The value range for the exp-value argument is 0 to 7. On EB, EC2, or FD card operating in basic ACL mode, a QoS policy applied to the outgoing traffic does not support a class that uses MPLS EXP values as match criteria.
mpls-label { label-value&<1-8> \| label-value1 to label-value2 }	Matches MPLS label values. The label-value&<1-8> argument specifies a list of up to eight MPLS label values. The label-value1 to label-value2 option specifies a range of MPLS label values. The value for label-value1 must be greater than or equal to the value for label-value2. The value range for the label-value argument is 0 to 1048575. On an EB, EC2, or FD card operating in basic ACL mode, a QoS policy does not support a class that uses MPLS labels as match criteria.
protocol protocol-name	Matches a protocol. The protocol-name argument can be arp, ip, or ipv6. On an EB, EC2, or FD card operating in basic ACL mode, a QoS policy does not support a class that uses the IPv6 protocol as a match criterion.
second-mpls-exp exp-value&<1-8>	Matches inner MPLS EXP values. The exp-value&<1-8> argument specifies a space-separated list of up to eight EXP values. The value range for the exp-value argument is 0 to 7. On an EB, EC2, or FD card operating in basic ACL mode, a QoS policy does not support a class that uses inner MPLS EXP values as match criteria.
second-mpls-label { label-value&<1-8> \| label-value1 to label-value2 }	Matches inner MPLS label values. The label-value&<1-8> argument specifies a list of up to eight MPLS label values. The label-value1 to label-value2 option specifies a range of MPLS label values. The value for label-value1 must be greater than or equal to the value for label-value2. The value range for the label-value argument is 0 to 1048575. On an EB, EC2, or FD card operating in basic ACL mode, a QoS policy does not support a class that uses inner MPLS labels as match criteria.
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.
source-mac mac-address	Matches a source MAC address. On an EB, EC2, or FD card operating in basic ACL mode, suppose a QoS policy contains a class using a source MAC address as a match criterion. · If the QoS policy is applied to the incoming traffic, the class does not take effect on IPv4 packets. · If the QoS policy is applied to the outgoing traffic, the class does not take effect on IPv4 or IPv6 packets. · If the QoS policy is applied to the incoming or outgoing traffic, the class does not take effect on ARP packets.

Usage guidelines

When defining match criteria, use the usage guidelines described in these subsections.

Defining an ACL-based match criterion

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

· You can configure multiple ACL-based match criteria for a class.

· In a class with the operator as OR, 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. In a class with the operator as AND, you can add only one if-match statement that uses an ACL as a match criterion by specifying the name or number of the ACL.

· The deny action in an ACL rule means not executing the behavior of the corresponding class-behavior association. The permit action in an ACL rule means executing the behavior of the corresponding class-behavior association.

Defining a criterion to match a destination MAC address

· You can configure multiple destination MAC address match criteria for a traffic class.

· A destination MAC address match criterion is significant only to Ethernet interfaces.

Defining a criterion to match a source MAC address

· You can configure multiple source MAC address match criteria for a traffic class.

· A criterion to match a source MAC address is significant only to Ethernet interfaces.

Defining a criterion to match DSCP values

· You can configure multiple DSCP match criteria for a traffic class. All defined DSCP values are automatically sorted in ascending order.

· 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 as one. If a packet matches one of the defined DSCP values, it matches the if-match clause.

· To delete a criterion that matches DSCP values, the specified DSCP values must be identical with those defined in the criterion (the sequence can be different).

Defining a criterion to match 802.1p priority

· You can configure multiple 802.1p priority match criteria for a traffic class. All the defined 802.1p values are automatically arranged in ascending order.

· You can configure up to eight 802.1p priority values in one command line. If the same 802.1p priority value is specified multiple times, the system considers the values as one. If a packet matches one of the defined 802.1p priority values, it matches the if-match clause.

· To delete a criterion that matches 802.1p priority values, the specified 802.1p priority values in the command must be identical with those defined in the criterion (the sequence can be different).

Defining a criterion to match IP precedence values

· You can configure multiple IP precedence match criteria for a traffic class. The defined IP precedence values are automatically arranged in ascending order.

· 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 as one. If a packet matches one of the defined IP precedence values, it matches the if-match clause.

· To delete a criterion that matches IP precedence values, the specified IP precedence values in the command must be identical with those defined in the criterion (the sequence can be different).

Defining a criterion to match MPLS EXP values

· You can configure multiple MPLS EXP match criteria for a traffic class. The defined MPLS EXP values are automatically arranged in ascending order.

· 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 as one. If a packet matches one of the defined MPLS EXP values, it matches the if-match clause.

· To delete a criterion that matches MPLS EXP values, the specified MPLS EXP values in the command must be identical with those defined in the criterion (the sequence can be different).

· The MPLS EXP field exists only in MPLS packets, so this match criterion takes effect only on MPLS packets.

· As for software forwarding QoS, MPLS packets do not support IP-related matching rules.

Defining a criterion to match MPLS labels

· You can configure multiple MPLS label match criteria for a traffic class. The defined MPLS labels are automatically arranged in ascending order.

· You can configure multiple MPLS label values in one command. If the same MPLS label value is specified multiple times, the system considers the values as one. If a packet matches one of the defined MPLS label values, it matches the if-match clause.

· To delete a criterion that matches MPLS label values, the specified MPLS label values in the command must be identical with those defined in the criterion (the sequence can be different).

Defining a criterion to match VLAN IDs in inner or outer VLAN tags

· You can configure multiple VLAN ID match criteria for a traffic class. The defined VLAN IDs are automatically arranged in ascending order.

· You can configure multiple VLAN IDs in one command line. If the same VLAN ID is specified multiple times, the system considers the VLAN IDs as one. If a packet matches one of the defined VLAN IDs, it matches the if-match clause.

· To delete a criterion that matches VLAN IDs, the specified VLAN IDs in the command must be identical with those defined in the criterion (the sequence can be different).

· You can use the VLAN ID in the outer VLAN tag to match single-tagged packets.

Defining a criterion to match control plane protocols

· You can configure multiple control plane protocol match criteria for a traffic class.

· You can configure up to eight control plane protocols in one command line for a class with the operator as OR. If the same control plane protocol is specified multiple times, the system considers them as one. If a packet matches one of the defined control plane protocols, it matches the if-match clause.

· To delete a criterion that matches control plane protocols, the specified control plane protocols in the command must be identical with those defined in the criterion (the sequence can be different).

· If you specify different rate limit values for the same protocol in multiple class-behavior associations, the smallest rate limit value takes effect.

Parameters

cir committed-information-rate: Specifies the committed information rate (CIR), an average traffic rate. The value range for committed-information-rate is 1 to 100000000 kbps.

cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes, in the range of 1553 to 2147450880. By default, the CBS is the amount of traffic transmitted at the rate of CIR over 500 milliseconds. The CBS must be greater than the maximum packet length. If the traffic transmitted at the rate of CIR over 500 milliseconds is smaller than 1553, the default CBS is 1553.

ebs excess-burst-size: Specifies the excess burst size (EBS) in bytes, in the range of 0 to 2147450880 and defaulting to 0.

pir peak-information-rate: Specifies the peak information rate (PIR) in the range of 1 to 100000000 kbps.

red action: Specifies the action to take on the packet that conforms to neither CIR nor PIR. The default is discard.

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, 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 CAR action can be applied to either 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.

H3C recommends that you set the committed-burst-size argument, if necessary, to be greater than 6.25 times the committed-information-rate argument to accommodate traffic bursts.

Examples

# Configure a CAR action in traffic behavior database as follows:

· Set the CIR to 200 kbps and CBS to 50000 bytes.

· Transmit the conforming packets, and discard the excess packets.

redirect

Use redirect to configure a traffic redirecting action in a traffic behavior.

Use undo redirect to delete the action.

Syntax

redirect { cpu | interface interface-type interface-number [ track-oap ] [ vlan vlan-id ] }

undo redirect { cpu | interface interface-type interface-number }

Default

No traffic redirecting action is configured.

Views

Traffic behavior view

Predefined user roles

network-admin

mdc-admin

Parameters

cpu: Redirects traffic to the CPU.

interface: Redirects traffic to an interface.

interface-type interface-number: Specifies an interface by its type and number. Only Layer 2 Ethernet interfaces and Layer 2 aggregate interfaces are supported.

track-oap: Redirects traffic only when OAP clients are present.

vlan vlan-id: Tags traffic redirected to an interface with the VLAN tag specified by vlan-id. The value range for vlan-id is 1 to 4094.

Usage guidelines

Redirecting traffic to the CPU and redirecting traffic to an interface are mutually exclusive with each other in the same traffic behavior. The most recently configured redirecting action takes effect.

If you specify the track-oap keyword, the switch detects the presence of OAP clients and redirects traffic to the interface only when OAP clients are present.

In IRF mode, the switch does not support redirecting traffic to an aggregate interface.

In IRF mode, the switch supports multichassis redirecting only for OAP cards. Multichassis redirecting refers to redirecting traffic to an outgoing interface on a different IRF member device than the incoming interface.

Use undo qos apply policy to remove the applied QoS policy.

Syntax

qos apply policy policy-name { inbound | outbound }

mdc-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

QoS policies cannot be applied to VLAN or aggregate interfaces.

In a QoS policy, do not configure the car cir or filter deny command in the associated traffic behavior of a class when the following conditions exist:

· In the class, an Ethernet frame header ACL with a rule that permits all packets is used as the match criterion.

· The QoS policy is to be applied to the control plane of the card where an IRF physical port resides.

Otherwise, an IRF split might occur.

Examples

# Apply the QoS policy USER1 to the incoming traffic of GigabitEthernet 3/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 3/0/1

mdc-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 in the inbound direction.

outbound: Applies the QoS policy in the outbound direction.

Usage guidelines

A QoS policy globally applied takes effect on all incoming or outgoing traffic, depending on the direction in which the QoS policy is applied.

If the hardware resources of an interface card are insufficient, applying a QoS policy globally might fail on the interface card. In this case, the system does not automatically roll back the QoS policy configuration already applied to the MPU or other interface cards. To ensure consistency, you must manually remove the QoS policy configuration applied to them. Do the same thing if a global QoS policy fails to update on an interface card after being dynamically modified.

Examples

# Apply the QoS policy user1 globally in the inbound direction.

<Sysname> system-view

[Sysname] qos apply policy user1 global inbound

qos policy

Usage guidelines

VLAN QoS policies will be applied globally to all interface cards. If the hardware resources of an interface card are insufficient, applying a QoS policy to VLANs might fail on the interface card. In this case, the system does not automatically roll back the QoS policy configuration already applied to the MPU or other interface cards. To ensure consistency, you must manually remove the QoS policy configuration applied to them. Do the same thing if a VLAN QoS policy fails to update on an interface card after being dynamically modified.

Parameters

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

vlan-id-list: Specifies a space-separated list of up to eight VLAN IDs or a VLAN ID range 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.

inbound: Applies the QoS policy to incoming packets.

outbound: Applies the QoS policy to outgoing packets.

Examples

# Apply the QoS policy test to the incoming traffic of VLAN 200, VLAN 300, VLAN 400, and VLAN 500.

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. Only this mode is supported.

cir committed-information-rate: Specifies the CIR in the range of 1 to 100000000 kbps.

cbs committed-burst-size: Specifies the CBS in bytes, the size of bursty traffic when the actual average rate is no greater than CIR. The value range for the committed-burst-size argument is 1553 to 2147450880. The specified CBS must be larger than the maximum packet length. By default, the CBS is the amount of traffic transmitted at the rate of CIR over 500 milliseconds. If the traffic transmitted at the rate of CIR over 500 milliseconds is smaller than 1553, the default CBS is 1553.

ebs excess-burst-size: Specifies the EBS in the range of 0 to 2147450880 bytes.

pir peak-information-rate: Specifies the PIR in the range of 1 to 100000000 kbps.

red action: Specifies the action to take on packets that conform to neither CIR nor PIR. The default setting is discard.

action: Specifies the action to take on packets:

· discard: Drops the packet.

· pass: Permits the packet to pass through.

Usage guidelines

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.

An aggregate CAR action takes effect only after it is used in a QoS policy.

H3C recommends that you set the committed-burst-size argument, if necessary, to be greater than 6.25 times the committed-information-rate argument to accommodate traffic bursts.

Examples

# Configure the aggregate CAR action aggcar-1, where CIR is 200, CBS is 2000, and red packets are dropped.

<Sysname> system-view

[Sysname] qos car aggcar-1 aggregative cir 200 cbs 2000 red discard

Parameters

inbound: Inbound direction.

outbound: Outbound direction.

counter0: Counter 0.

counter1: Counter 1.

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

drop-priority drop-priority: Specifies a drop priority in the range of 0 to 2.

interface interface-type interface-number: Specifies an interface by its type and number.

vlan vlan-id: Specifies a VLAN by its ID in the range of 1 to 4094.

Usage guidelines

A card provides two counters for traffic accounting. The monitored object can be an interface, a VLAN, or a drop priority value.

· If you do not specify an interface, the traffic of all the interfaces on the card is monitored.

· If you do not specify a VLAN, the traffic of all the VLANs is monitored.

· If you do not specify a drop priority value, the traffic with any drop priority value is monitored.

When you redefine the monitored object on a card with the qos traffic-counter command, the counter resets automatically.

The drop-priority keyword supports only the outbound direction.

FD and FG cards support counting only traffic on a specific interface, but not traffic of VLANs, drop priority values, or all interfaces. To specify an interface, specify the slot number and interface number.
