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 for a class, use the guidelines described in these subsections.

Defining ACL-based match criteria

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

For a class, you can reference an ACL twice, respectively by its name and 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 and POS 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 may 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 may be different).

· On an Ethernet interface card, 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.

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 Layer 2 aggregate interface.

vlan vlan-id: Tags traffic redirected to an interface with the VLAN tag specified by vlan-id, which ranges from 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 the redirect command to configure a traffic redirecting action in a traffic behavior.

Use the undo redirect command 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.

qos apply policy

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

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.

Description

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

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

You can apply a QoS policy to the control plane of only an Ethernet interface card.

A QoS policy to be applied to a logical RPR interface can be configured with only the filter action or mirror-to action. For more information about logical RPR interfaces, see High Availability Configuration Guide. For more information about the mirror-to action, see Network Management and Monitoring Configuration Guide.

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 properly.

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

NOTE:

If the hardware resources of an interface card are insufficient, applying a QoS policy globally may 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.

Examples

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

Description

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

Use the undo qos policy command 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.

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

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

NOTE:

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 may 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.

QoS pipe mode configuration commands

qos pipe-mode

Syntax

qos pipe-mode

undo qos pipe-mode

Views

System view

Default level

2: System level

Parameters

None

Description

Use the qos pipe-mode command to configure the QoS pipe mode.

Use the undo qos pipe-mode command to cancel the QoS pipe mode.

By default, the QoS pipe mode is not configured.

With the QoS pipe mode configured, packets can pass through any of the following networks and keep their DSCP values unchanged.

· MAC-in-MAC network

· MPLS L2VPN network

· MPLS L3VPN network

· VPLS network

As a result, the forwarding and scheduling of the IP packets on the downstream devices are not affected. For more information, see ACL and QoS Configuration Guide.
