Parameters

match-criteria: Match criterion. Table 1-2 shows the available criteria.

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

update acl [ ipv6 ] { acl-number | name acl-name }: Specifies a new ACL to replace the specified current ACL by the number or name of the new ACL.

Table 1-2 The keyword and argument combinations for the match-criteria argument

Keyword and argument combination	Description
acl { access-list-number \| name acl-name }	Matches an IPv4 ACL specified by its number or name. The access-list-number argument specifies an ACL by its number, which ranges from 2000 to 4999. The name acl-name keyword-argument combination specifies an ACL by its name. In a class configured with the operator and, the logical relationship between rules defined in the referenced IPv4 ACL is or.
acl ipv6 { access-list-number \| name acl-name }	Matches an IPv6 ACL specified by its number or name. The access-list-number argument specifies an ACL by its number, which ranges from 2000 to 3999. The name acl-name keyword-argument combination specifies an ACL by its name. In a class configured with the operator and, the logical relationship between rules defined in the referenced IPv6 ACL is or.
any	Matches all packets
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 ranges from 0 to 7.
customer-vlan-id { vlan-id-list \| vlan-id1 to vlan-id2 }	Matches packets of the VLANs of the customer network. The vlan-id-list argument is a list of up to eight VLAN IDs. The vlan-id1 to vlan-id2 argument specifies a VLAN ID range, where vlan-id1 must be smaller than vlan-id2. A VLAN ID ranges from 1 to 4094.
destination-mac mac-address	Matches a destination MAC address
dscp dscp-list	Matches DSCP values. The dscp-list is a list of DSCP values. A DSCP value is a number in the range 0 to 63 or a word representing the specific value.
ip-precedence ip-precedence-list	Matches IP precedence. The ip-precedence-list argument is a list of up to eight IP precedence values. An IP precedence value ranges from 0 to 7.
protocol protocol-name	Matches a protocol. The protocol-name argument can be IP or IPv6.
qos-local-id local-id-value	Matches a local QoS ID, which ranges from 1 to 4095.
service-dot1p 8021p-list	Matches the 802.1p priority of the service provider network. The 8021p-list argument is a list of up to eight 802.1p priority values. An 802.1p priority ranges from 0 to 7.
service-vlan-id { vlan-id-list \| vlan-id1 to vlan-id2 }	Matches the packets of the VLANs of the service provider network. The vlan-id-list argument is a list of up to eight VLAN IDs. The vlan-id1 to vlan-id2 argument specifies a VLAN ID range, where vlan-id1 must be smaller than vlan-id2. A VLAN ID ranges from 1 to 4094.
source-mac mac-address	Matches a source MAC address

Suppose the operator of a class is AND. Note the following when using the if-match command to define matching criteria for the class:

l If multiple matching criteria with the acl or acl ipv6 keyword specified are defined for the class, the actual logical relationship between these criteria is OR when a policy referencing the class is applied.

l If multiple match criteria with the customer-vlan-id or service-vlan-id keyword specified are defined for the class, the actual logical relationship between these criteria is OR.

The match criteria listed below must be unique in a class with the operator AND. Even though it is possible, avoid defining multiple if-match clauses for these match criteria or inputting multiple values for a list argument (such as the 8021p-list argument) listed below in a class. Otherwise, the QoS policy referencing the class cannot be successfully applied to interfaces.

l customer-dot1p 8021p-list

l destination-mac mac-address

l dscp dscp-list

l ip-precedence ip-precedence-list

l service-dot1p 8021p-list

l source-mac mac-address

To create multiple if-match clauses or specify multiple values for a list argument for any of the match criteria listed above, ensure that the operator of the class is OR.

A QoS policy referencing a if match customer-dot1p clause cannot be applied to outgoing traffic.

Description

Use the if-match command to define a match criterion.

Use the undo if-match command to remove the match criterion.

When defining match criteria, note the following:

1) Define an ACL-based match criterion

l If the ACL referenced in the if-match command does not exist, the class cannot be applied to hardware.

l For a class, you can reference an ACL twice by its name and number respectively with the if-match command.

2) Define a criterion to match a destination MAC address or a source MAC address.

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

3) Define a criterion to match DSCP values

l You can configure multiple DSCP match criteria for a class. All the defined DSCP values are automatically arranged in ascending order.

l You can configure up to eight DSCP values in one command line. If multiple identical DSCP values are specified, the system considers them as one. If a packet matches one of the defined DSCP values, it is considered as matching the if-match clause.

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

4) Define a criterion to match the 802.1p priority values of the customer network or service provider network

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

l 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 them as one. If a packet matches one of the defined 802.1p priority values, it is considered as matching the if-match clause.

l 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 may be different).

5) Define a criterion to match IP precedence values

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

l You can configure up to eight IP precedence values in one command line. If the same IP precedence is specified multiple times, the system considers them as one. If a packet matches one of the defined IP precedence values, it is considered as matching the if-match clause.

l 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 may be different).

6) Define a criterion to match customer network VLAN IDs or service provider network VLAN IDs

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

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

l 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 may be different).

View

Traffic behavior view

Default Level

2: System level

Parameters

cir committed-information-rate: Committed information rate (CIR) in kbps, which specifies the average traffic rate. The committed-information-rate argument ranges from 8 to 32000000 and must be a multiple of 8.

cbs committed-burst-size: Committed burst size (CBS) in bytes. The committed-burst-size argument ranges from 512 to 16000000 and defaults to 512.

ebs excess-burst-size: Excess burst size (EBS) in bytes. The excess-burst-size argument ranges from 0 to 16000000 and defaults to 512.

pir peak-information-rate: Peak information rate (PIR) in kbps. The peak-information-rate argument ranges from 8 to 32000000, and must be a multiple of 8.

green action: Action to take on packets that conform to CIR. The default is pass.

red action: Action to take on packets that conforms to neither CIR nor PIR. The default is discard.

yellow action: Action to take on packets that conform to PIR but not to CIR. The default is pass.

action: Action to take on packets, which can be:

l discard: Drops the packet.

l pass: Permits the packet to pass through.

l remark-dot1p-pass new-cos: Sets the 802.1p priority of the packet to new-cos and permits the packet to pass through. The new-cos argument ranges from 0 to 7.

l remark-dscp-pass new-dscp: Sets the DSCP value of the packet to new-dscp and permits the packet to pass through. The new-dscp argument ranges from 0 to 63.

l 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 ranges from 0 to 7.

hierarchy-car-name: Name of the referenced hierarchical CAR.

mode: Collaborating mode of the hierarchical CAR action and the common CAR action, which can be AND (the default) or OR.

l AND mode (the and keyword), in which the traffic rate of a flow is limited by both the common CAR applied to it and the total traffic rate defined with hierarchical CAR. For example, you can use common CAR actions to limit the Internet access rates of flow 1 and flow 2 to 128 kbps each, and use a hierarchical CAR action to limit their total traffic rate to 192 kbps. Thus, when flow 1 is not present, flow 2 can access the Internet at the maximum rate, 128 kbps. If both flows are present, each flow cannot exceed its own rate limit, and the total rate cannot exceed 192 kbps.

l OR mode (the or keyword), in which a flow may pass through at an rate equal to the common CAR applied to it or at a higher rate if the total traffic rate of all flows does not exceed the hierarchical CAR. For example, you can use generic CAR actions to limit the rates of video flow 1 and flow 2 to 128 kbps each, and use a hierarchical CAR action to limit their total traffic rate to 512 kbps. As long as the rate of flow 1 does not exceed 128 kbps, flow 2 can pass at a rate up to 384 kbps.

Description

Use the car command to configure a CAR action for the traffic behavior.

Use the undo car command to remove the CAR action from the traffic behavior.

Note that: if this command is configured multiple times for the same traffic behavior, the last configuration takes effect.

qos apply policy (interface view, port group view)

Syntax

qos apply policy policy-name { inbound | outbound }

undo qos apply policy { inbound | outbound }

View

Interface view, port group view

Default Level

2: System level

Parameters

inbound: Inbound direction.

outbound: Outbound direction.

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

Description

Use the qos apply policy command to apply a QoS policy.

Use the undo qos apply policy command to cancel the QoS policy application.

Settings in interface view are effective on the current interface. Settings in port group view are effective on all ports in the port group.

Examples

# Apply policy USER1 to the outgoing traffic of interface GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] qos apply policy USER1 outbound

qos apply policy (user-profile view)

Syntax

qos apply policy policy-name { inbound | outbound }

undo qos apply policy { inbound | outbound }

View

User profile view

Default Level

2: System level

Parameters

inbound: Applies the QoS policy to the incoming traffic of online users.

outbound: Applies the QoS policy to the outgoing traffic of online users.

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

Description

Use the qos apply policy command to apply a QoS policy to a user profile.

Use the undo qos apply policy command to cancel the QoS policy application.

Note that:

l If a user profile is activated, the QoS policy applied to it cannot be configured or removed, except the ACLs referenced in the QoS policy. However, when the users of the user profile are online, the referenced ACLs also cannot be modified.

l The QoS policy applied to a user profile becomes effective when the user-profile is activated and the corresponding users are online.

l Only the remark, car, and filter actions are supported in the QoS policies applied in user profile view.

l A null policy cannot be applied in user profile view.

Examples

# Apply policy test to the outgoing traffic of the online users of user profile user. (Assume that that the QoS policy has been configured.)

<Sysname> system-view

[Sysname] user-profile user

[Sysname-user-profile-user] qos apply policy test outbound
