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.
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	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.
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.
local-precedence local-precedence-value&<1-8>	Matches local precedence values. The local-precedence-value&<1-8> argument specifies a space-separated list of up to eight local precedence values. The value range for the local-precedence-value argument is 0 to 7.
protocol protocol-name	Matches a protocol. The protocol-name argument can be arp, ip, bittorrent, or ipv6.
source-mac mac-address	Matches a source MAC address. This option takes effect only on Ethernet interfaces.

‌

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.

¡ DSCP.

¡ IP precedence.

¡ Local precedence.

· 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.

To use an ACL match criterion, the ACL must already exist.

· Do not contain deny rules in the ACL. Actions in the QoS policy are not taken on traffic matching a deny rule.

You can use both AND and OR operators to define the match relationships between the criteria for a class. For example, you can define relationships among three match criteria in traffic class classA as follows:

traffic classifier classB operator and

if-match criterion 1

if-match criterion 2

traffic classifier classA operator or

if-match criterion 3

if-match classifier classB

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.

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.

The undo classifier default-class command performs the following operations:

· Deletes the existing class-behavior association for the system-defined class default-class.

· Associates the system-defined class default-class with the system-defined behavior be.

Parameters

interval: Specifies the QoS policy-based traffic rate statistics collection period in minutes. The value range for this argument is 1 to 10.

Usage guidelines

You can enable collection of per-class traffic statistics over a period of time, including the average forwarding rate and drop rate. For example, if you set the statistics collection period to 10 minutes, the system performs the following operations:

· Collects traffic statistics for the most recent 10 minutes.

· Refreshes the statistics every 10/5 minutes, 2 minutes.

The traffic rate statistics collection period of a subinterface is the same as the period configured on the main interface.

Parameters

interface-type interface-number: Specifies an interface by its type and number. If you do not specify an interface, this command displays the priority trust mode and port priorities of all interfaces.

Examples

# Display the priority trust mode and port priority of GigabitEthernet 1/0/1.

<Sysname> display qos trust interface gigabitethernet 1/0/1

Interface: GigabitEthernet1/0/1

Port priority trust information

Port priority: 4

Port priority trust type: dscp, Override: disable

Table 3 Command output

Field	Description
Interface	Interface type and interface number.
Port priority	Port priority set for the interface.
Port dscp priority	DSCP value rewritten for packets. If you have not rewritten the DSCP value of packets, this field displays a hyphen (-).
Port priority trust type	Priority trust mode on the interface: · dot1p—Uses the 802.1p priority of received packets for mapping. · dscp—Uses the DSCP precedence of received IP packets for mapping. · none—Trusts no packet priority.
Override	Indicates whether the precedence derived through priority mapping overwrites the original precedence carried in the packet.

qos trust

Use qos trust to configure the priority trust mode for an interface.

Use undo qos trust to restore the default.

Syntax

qos trust { dot1p | dscp }

undo qos trust

Default

An interface does not trust any packet priority and uses the port priority as the 802.1p priority for mapping.

Views

network-admin

Parameters

dot1p: Uses the 802.1p priority in incoming packets for priority mapping.

dscp: Uses the DSCP value in incoming packets for priority mapping.

Usage guidelines

For a VXLAN tunnel interface to trust the DSCP priority in the inner IP header of VXLAN packets, configure the qos trust dscp command on its physical interface.

Examples

# Set the priority trust mode to 802.1p priority on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] qos trust dot1p

Port priority commands

qos priority

Use qos priority to change the port priority of an interface.

Use undo qos priority to restore the default.

Syntax

undo qos priority

Default

The port priority is 0.
