Parameters

match-criteria: Match criterion. Table 2 shows the available criteria.

acl [ ipv6 ] { acl-number | name acl-name }: Specifies an ACL already referenced in the class by the ACL name or ACL number.

update acl [ ipv6 ] { acl-number | name acl-name }: Specifies a new ACL by its number or name to replace the ACL already referenced by the class.

Table 2 The options for the match-criteria argument

Option	Description
acl [ ipv6 ] { acl-number \| name acl-name }	Matches an ACL. The acl-number argument is in the range of 2000 to 5999 for an IPv4 ACL, and 2000 to 3999 for an IPv6 ACL. The acl-name argument is a case-insensitive string of 1 to 63 characters, which must start with an English letter from a to z or A to Z and cannot be all to avoid confusion. You can use a user-defined ACL in a QoS policy only to identify inbound traffic. On an EB or EC2 card operating in standard ACL mode, a QoS policy does not support a class that uses IPv6 ACLs or user-defined ACLs as match criteria.
customer-dot1p 8021p-list	Matches the 802.1p priority of the customer network. The 8021p-list argument is a list of up to eight 802.1p priority values. An 802.1p priority is in the range of 0 to 7. This keyword is not supported in a global QoS policy or VLAN QoS policy. On an EB or EC2 card operating in standard ACL mode, a QoS policy does not support a class that uses the 802.1p priority values of the customer network as match criteria.
customer-vlan-id { vlan-id-list \| vlan-id1 to vlan-id2 }	Matches the VLAN IDs of customer networks. The vlan-id-list argument is a list of up to eight VLAN IDs. vlan-id1 to vlan-id2 specifies a VLAN ID range, where vlan-id1 must be smaller than vlan-id2. A VLAN ID is in the range of 1 to 4094. This keyword is not supported in a global QoS policy or VLAN QoS policy. On an EB or EC2 card operating in standard ACL mode, a QoS policy does not support a class that uses the VLAN IDs of customer networks as match criteria.
destination-mac mac-address	Matches a destination MAC address. On an EB or EC2 card operating in standard ACL mode, if a QoS policy that references a class using a destination MAC address as a match criterion is applied to the incoming traffic, the class does not take effect on IPv4 packets. If a QoS policy that references a class using a destination MAC address as a match criterion is applied to the outgoing traffic, the class does not take effect on IPv4 or IPv6 packets.
dscp dscp-list	Matches DSCP values. The dscp-list argument is a list of up to eight DSCP values. A DSCP value is in the range of 0 to 63.
inbound-interface interface-type interface-number	Matches an inbound interfaces specified by its type and number. A QoS policy configured with the match criteria can be applied to only a control plane. To make sure the QoS policy can be applied successfully, the inbound interface specified and the control plane that you apply the QoS policy to must be in the same slot. When you use this keyword as the match criteria of a class, you can configure only filter or car in the behavior associated with the class.
forwarding-layer { bridge \| route }	Matches Layer 2 packets by specifying the bridge keyword or Layer 3 packets by specifying the route keyword.
ip-precedence ip-precedence-list	Matches IP precedence. The ip-precedence-list argument is a list of up to 8 IP precedence values. An IP precedence is in the range of 0 to 7.
mpls-exp exp-list	Matches outer MPLS EXP values. The exp-list argument is a list of up to 8 EXP values. An EXP value is in the range of 0 to 7.

mpls-label { label-id-list \| label-id1 to label-id2 }	Matches outer MPLS labels. The label-value-list argument specifies a list of up to eight MPLS label values. label-value1 to label-value2 specifies an MPLS label value range, where label-value1 must be smaller than label-value2. An MPLS label value is in the range of 1 to 1048575. On an EB or EC2 card operating in standard ACL mode, a QoS policy does not support a class that uses the MPLS labels as match criteria.
protocol protocol-name	Matches a protocol. The protocol-name can be ARP, IP, or IPv6. On an EB or EC2 card operating in standard ACL mode, a QoS policy does not support a class that uses the IPv6 protocol as the match criterion.
second-mpls-exp exp-list	Matches inner MPLS EXP values. The exp-list argument is a list of up to 8 EXP values. An EXP value is in the range of 0 to 7. On an EB or EC2 card operating in standard ACL mode, a QoS policy does not support a class that uses the inner MPLS EXP value as match criteria.
second-mpls-label { label-id-list \| label-id1 to label-id2 }	Matches inner MPLS labels. The label-value-list argument specifies a list of up to eight MPLS label values. label-value1 to label-value2 specifies an MPLS label range, where label-value1 must be smaller than label-value2.

service-vlan-id { vlan-id-list \| vlan-id1 to vlan-id2 }	Matches the VLAN IDs of ISP networks. The vlan-id-list argument is a list of up to 8 VLAN IDs. vlan-id1 to vlan-id2 specifies a VLAN ID range, where vlan-id1 must be smaller than vlan-id2. A VLAN ID is in the range of 1 to 4094.
system-index index-value-list	Matches a pre-defined match criterion (system-index) for packets sent to the control plane. The index-value-list argument specifies a list of up to eight system indexes. A system index is in the range of 1 to 28. To see the detailed information about a system index, use the display qos policy control-plane pre-defined command. When you configure the system index match criteria for a class to match the packets sent to the control plane, you cannot configure any other match criteria for the class, and you can associate only a behavior configured with the packet-rate command with the class.
source-mac mac-address	Matches a source MAC address. On an EB or EC2 card operating in standard ACL mode, if a QoS policy that references a class using a source MAC address as a match criterion is applied to the incoming traffic, the class does not take effect on IPv4 packets. If a QoS policy that references a class using a source MAC address as a match criterion is applied to the outgoing traffic, the class does not take effect on IPv4 or IPv6 packets.

Description

Use if-match to define a match criterion.

Use undo if-match to remove the match criterion.

When defining match criteria for a class, use the guidelines described in these subsections.

Defining ACL-based match criteria

Make sure the ACL you are using has been created. If not, the class cannot be applied to hardware.

For a class with the operator as OR, you can reference an ACL twice, respectively by its name and number. For a class with the operator as AND, you can reference an ACL only once by its name or number.

Defining destination MAC address criteria

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

Defining source MAC address criteria

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

Defining DSCP precedence criteria

· You can configure multiple DSCP precedence match clause for a class. They are automatically sorted in the order they are configured.

· You can configure up to eight DSCP values in one match clause. Identical DSCP values are counted as one. If a packet matches one of the DSCP values, it matches the match clause.

· To delete a DSCP match clause, execute the undo if-match command with the same list of DSCP values, not necessarily in the same order, as in the match clause.

Defining inbound interface match criteria

· You can configure multiple inbound interface match criteria for a class.

· The inbound interfaces specified as the match criteria must already exist. If a dynamic interface is specified in the inbound interface match criterion, the match criterion is deleted when the interface is deleted.

· The match criteria are available only on Ethernet interfaces.

Defining 802.1p priority criteria for matching customer-side or service provider-side traffic

· You can configure multiple 802.1p priority match clauses for a class. They are automatically sorted in the ascending number order.

· You can configure up to eight unique 802.1p priority values in one match clause. Identical 802.1p priority values are counted as one. If a packet matches one of the 802.1p priority values, it matches the match clause.

· To delete an 802.1p priority match clause, execute the undo if-match command with the same list of 802.1p priority values, not necessarily in the same order, as in the match clause.

Defining IP precedence criteria

· You can configure multiple IP precedence match clauses for a class. They are automatically sorted in the order they are configured.

· You can configure up to eight unique IP precedence values in one match clause. Identical IP precedence values are counted as one. If a packet matches one of the IP precedence values, it matches the match clause.

· To delete an IP precedence match clause, execute the undo if-match command with the same list of IP precedence values, not necessarily in the same order, as in the match clause.

Defining MPLS EXP precedence criteria

· You can configure multiple MPLS EXP precedence match clauses for a class. They are automatically sorted in ascending order.

· You can configure up to eight unique MPLS EXP precedence values in one match clause. Identical MPLS EXP precedence values are counted as one. If a packet matches one of the MPLS EXP values, it matches the match clause.

· To delete an MPLS EXP precedence match clause, execute the undo if-match command with the same list of MPLS EXP precedence values, not necessarily in the same order, as in the match clause.

· MPLS EXP match criteria apply only to MPLS packets.

· IP match criteria do not apply to MPLS packets.

Defining MPLS label criteria

· You can configure multiple MPLS label match clauses for a class. The MPLS labels are automatically sorted in ascending order.

· You can configure up to eight unique MPLS labels in one match clause. Identical MPLS labels are counted as one. If a packet matches one of the MPLS labels, it matches the match clause.

· To delete an MPLS label match clause, execute the undo if-match command with the same list of MPLS labels, not necessarily in the same order, as in the match clause.

· MPLS label criteria apply only to MPLS packets.

Defining VLAN ID criteria for matching customer VLAN or service provider VLAN traffic

· You can configure multiple VLAN ID match clauses for a class. The VLAN IDs are automatically sorted in the order they are configured.

· You can configure multiple VLAN IDs in one match clause. Identical VLAN IDs are counted as one. If a packet matches one of the VLAN IDs, it matches the match clause.

· To delete a VLAN ID match clause, execute the undo if-match command with the same list of VLAN IDs, not necessarily in the same order, as in the match clause.

Referencing a pre-define match criterion for packets sent to the control plane

· You can configure multiple match criteria in a class for packets sent to the control plane.

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

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

· you can use the display qos policy control-plane pre-defined command to display the pre-defined match criteria for packets sent to the control plane of the device.

Defining Layer 2 or Layer 3 packet criteria

· The if-match forwarding-layer bridge and if-match forwarding-layer route commands are mutually exclusive in a class.

· You must use a forwarding-layer match criterion together with other match criteria. The other match criteria in the class cannot conflict with the forwarding-layer match criterion, regardless of the operator of the class.

Default level

2: System level

Parameters

cpu: Redirects traffic to the CPU.

interface interface-type interface-number: Redirects traffic to the interface specified by its interface number and interface type. The interface can be a normal Ethernet interface or a Layer 2 aggregate interface.

vlan vlan-id: Tags traffic redirected to an interface with the VLAN tag specified by vlan-id in the range of 1 to 4094.

next-hop: Redirects traffic to a next hop.

ipv4-add1/ipv4-add2: IPv4 address of the next hop. The ipv4-add2 argument backs up ipv4-add1. If redirecting traffic to ipv4-add1 fails, the switch redirects the traffic to ipv4-add2.

ipv6-add1/ipv6-add2: IPv6 address of the next hop. The ipv6-add2 argument backs up ipv6-add1. If redirecting traffic to ipv6-add1 fails, traffic will be redirected to ipv6-add2. If the specified next hop IPv6 address is a link-local address, you must also specify the outgoing interface. If otherwise, you do not need to specify the outgoing interface.

fail-action { discard | forward }: Specifies the action to take on a packet whose next hop address does not exist.

· discard: Drops the packet.

· forward: Forwards the packet by common routing. The fail-action keyword is forward by default.

Description

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

Use undo redirect to delete the traffic redirecting action.

In IRF mode, the switch cannot redirect traffic to an aggregate interface.

Different from destination-based routing, QoS policy routing makes routing decisions based on the source address and other criteria. QoS policy routing takes precedence over destination-based routing. If a packet meets the match criteria, QoS policy routing applies. If not, destination-based routing applies.

In standalone mode, the switch does not support redirecting traffic to an aggregate interface on an LST1IPS2A1 card.

In IRF mode, the switch does not support redirecting traffic to the second internal port on an LST1IPS2A1 card on another member device.

To redirect traffic correctly to an internal port on an LST1IPS2A1 card by using a QoS policy, you must perform the following tasks:

· Assign the two internal ports to an aggregation group. Do not assign any other interface to the aggregation group.

· Set the minimum number of Selected ports in the aggregation group to 2.

Use traffic behavior to create a traffic behavior and enter traffic behavior view.

Use undo traffic behavior to delete a traffic behavior.

A traffic behavior is a set of actions, such as priority marking, dropping, rate limiting, and accounting. You provide QoS for a class of traffic by associating a traffic behavior with the class of traffic.

Related commands: qos policy, qos apply policy, and classifier behavior.

Examples

# Create traffic behavior behavior1 or enter its view.

<Sysname> system-view

[Sysname] traffic behavior behavior1

2: System level

Parameters

tcl-name: Specifies a traffic class name, a string of 1 to 31 characters.

behavior-name: Specifies a traffic behavior name, a string of 1 to 31 characters.

Description

Use classifier behavior to associate a behavior with a class in a QoS policy.

Use undo classifier to remove the class from the policy.

You can perform a set of QoS actions on a traffic class by associating a traffic behavior with the traffic class.

You can assign multiple classes to a QoS policy, and each class can associate with only one traffic behavior.

If the specified class or traffic behavior does not exist, the system creates a null class or traffic behavior.

Related commands: qos policy.

Examples

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

qos apply policy

Syntax

qos apply policy policy-name { inbound | outbound }

undo qos apply policy [ policy-name ] { inbound | outbound }

View

Interface view, port group view, control plane view

Default level

2: System level

Parameters

policy policy-name: Specifies a policy by its name, which is a string of 1 to 31 characters.

inbound: Applies the QoS policy in the inbound direction.

outbound: Applies the QoS policy in the outbound direction. This keyword is not available in control plane view.

Description

Use qos apply policy to apply a QoS policy to an interface, all ports in a port group, or the control plane.

Use undo qos apply policy to remove the QoS policy.

When you apply a QoS policy to the control plane of the slot where the IRF port resides, if a class in the QoS policy uses an Ethernet frame header ACL configured with rule permit to match all packets, do not configure car cir or filter deny in the behavior associated with the class. Otherwise, the IRF might split, and the switch cannot work correctly.

If you apply a QoS policy whose name is inbound (case-insensitive), outbound (case-insensitive), or the first several characters (case-insensitive) of inbound or outbound in interface view, port group view, or control plane view, to remove the QoS policy, you can only use the undo qos apply policy command without specifying the QoS policy name.

Examples

# Apply policy USER1 in the outbound direction of GigabitEthernet 3/0/1.

<Sysname> system-view

[Sysname] interface GigabitEthernet 3/0/1

[Sysname-GigabitEthernet3/0/1] qos apply policy USER1 outbound

qos apply policy global

Syntax

qos apply policy policy-name global { inbound | outbound }

undo qos apply policy [ policy-name ] global { inbound | outbound }

View

System view

Default level

2: System level

Parameters

policy-name: Policy name, a string of 1 to 31 characters.

inbound: Applies the QoS policy to the incoming packets on all ports.

outbound: Applies the QoS policy to the outgoing packets on all ports.

Description

Use qos apply policy global to apply a QoS policy globally. A global QoS policy takes effect on all inbound or outbound traffic depending on the direction in which the policy is applied.

Use undo qos apply policy global to cancel the global application of the QoS policy.

If the hardware resources of an interface card are insufficient, applying a QoS policy globally will fail on the interface card. In this case, the system does not automatically roll back the QoS policy configuration already applied to the main processing unit 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.

If you globally apply a QoS policy whose name is global (case-insensitive) or the first several characters (case-insensitive) of global, to remove the QoS policy, you can only use the undo qos apply policy global command without specifying the QoS policy name.

Examples

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

Parameters

policy policy-name: Policy name, a string of 1 to 31 characters.

Description

Use qos policy to create a policy and enter policy view.

Use undo qos policy to remove a policy.

You cannot delete a policy that has been applied. To delete a policy that has been applied, for example, to an interface, you must remove the policy from the interface first.

Default level

2: System level

Parameters

policy-name: QoS policy name, a string of 1 to 31 characters.

vlan-id-list: A list of up to eight VLAN IDs in the range 1 to 4094. You can input individual discontinuous VLAN IDs and VLAN ID ranges in the form of start-vlan-id to end-vlan-id where the start VLAN ID must be smaller than the end VLAN ID. Each item in the VLAN list is separated by a space. These VLANs must be manually created VLANs that already exist.

inbound: Applies the QoS policy to the incoming packets in the specified VLAN(s).

outbound: Applies the QoS policy to the outgoing packets in the specified VLAN(s).

Description

Use qos vlan-policy to apply a QoS policy to the specified VLAN(s).

Use undo qos vlan-policy to remove the QoS policy applied to the specified VLAN(s).

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 will fail on the interface card. In this case, the system does not automatically roll back the QoS policy configuration already applied to the main processing unit 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.

If you apply a QoS policy whose name is vlan (case-insensitive) or the first several characters (case-insensitive) of vlan in VLAN view, to remove the QoS policy, you can only use the undo qos vlan-policy command without specifying the QoS policy name.
