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. 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.
app-group group-name	Matches an application group. The group-name argument specifies an application group by its name. The application group must have been created. A nonexistent application group cannot match packets. For more information about creating application groups, see APR in Security Configuration Guide.
application app-name	Matches an application. The app-name argument specifies a user-created application by its name.
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:

¡ 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.

When you configure ACL-based match criteria, follow these restrictions and guidelines:

· The ACL must already exist.

· A deny rule does not take effect and cannot match packets.

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. 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.

A QoS policy can contain multiple class-behavior associations. The device matches a packet against the class-behavior associations in their configuration order. When a match is found, the device stops the match process and takes the actions in the matching class-behavior association.

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.

Examples

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

<Sysname> system-view

Predefined user roles

network-admin

Parameters

bandwidth: Specifies the bandwidth in kbps. The value range for this argument is 8 to 1000000.

pct percentage: Specifies the percentage of the available bandwidth, in the range of 1 to 100.

remaining-pct remaining-percentage: Specifies the percentage of the remaining bandwidth, in the range of 1 to 100.

Usage guidelines

To associate the traffic behavior configured with the queue af command with a class in a policy, you must follow these requirements:

· The total bandwidth assigned to AF and EF queues in a policy cannot exceed the maximum available bandwidth of the interface where the policy is applied.

· The total percentage of bandwidth assigned to AF and EF in a policy cannot exceed 100.

· The bandwidth assigned to AF and EF in a policy must use the same form, either as an absolute bandwidth value or as a percentage.

If you execute the queue af command multiple times, the most recent configuration takes effect.

Examples

# Configure AF in traffic behavior database and assign the minimum guaranteed bandwidth 200 kbps to it.

Parameters

bandwidth: Specifies the bandwidth in kbps. The value range for this argument is 8 to 1000000.

cbs burst: Sets the CBS in bytes. The value range for this argument is 32 to 1000000000. The default is bandwidth × 25.

pct percentage: Specifies the percentage of the available bandwidth, in the range of 1 to 100.

cbs-ratio ratio: Sets the allowed burst ratio in the range of 25 to 500. This default is 25.

Usage guidelines

You cannot use this command in conjunction with the queue af or queue-length command in the same traffic behavior.

In a policy, the default class cannot be associated with the traffic behavior that has the queue ef command.

The total bandwidth assigned to AF and EF in a policy cannot exceed the maximum available bandwidth of the interface where the policy is applied.

The total percentage of the maximum available bandwidth assigned to AF and EF in a policy cannot exceed 100.

The bandwidths assigned to AF and EF in a policy must have the same type, bandwidth or percentage.

After the queue ef bandwidth pct percentage [ cbs-ratio ratio ] command is used, CBS equals (Interface available bandwidth × percentage × ratio)/100/1000.

After the queue ef bandwidth bandwidth [ cbs burst ] command is used, CBS equals burst. If the burst argument is not specified, CBS equals bandwidth × 25.

If you execute the queue ef command multiple times, the most recent configuration takes effect.

Examples

# Configure EF in traffic behavior database, with the maximum bandwidth as 200 kbps and CBS as 5000 bytes.

Parameters

queue-length: Specifies the maximum number of packets allowed in the FIFO queue. The value range for this argument is 1 to 1024.

Usage guidelines

Before configuring this command, make sure the queue af command or the queue wfq command has been configured.

The undo queue af or undo queue wfq command deletes the queue length configured by using the queue-length command.

If you execute the queue-length command multiple times, the most recent configuration takes effect.

Examples

# Set the maximum queue length to 16 and specify tail drop for AF.
