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:

¡ 802.1p priority.

¡ DSCP.

¡ IP precedence.

¡ MPLS EXP.

¡ VLAN ID.

· 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 used as a match criterion must already exist.

· Before defining a criterion to match the inner packet information of VXLAN packets in a traffic class, you must use the if-match vxlan command to define a VXLAN ID match criterion.

· The ACL is used for classification only and the permit/deny actions in ACL rules are ignored. Actions taken on matching packets are defined in traffic behaviors.

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

cir committed-information-rate: Specifies the committed information rate (CIR) in the range of 1 to 300000000 kbps.

cbs committed-burst-size: Specifies the committed burst size (CBS) in the range of 512 to 256000000 bytes. The default value for this argument is the product of 62.5 and the CIR.

ebs excess-burst-size: Specifies the excess burst size (EBS) in the range of 0 to 256000000 bytes. The default value for this argument is the product of 62.5 and the PIR.

pir peak-information-rate: Specifies the peak information rate (PIR) in kbps or pps. If you specify the pps keyword, the PIR is specified in pps. If you do not specify the pps keyword, the PIR is specified in kbps. The PIR must be specified in the same unit as the CIR. The value range for peak-information-rate is 1 to 300000000.

green action: Specifies the action to take on packets that conform to the CIR. The default setting is pass.

red action: Specifies the action to take on packets that conform to neither CIR nor PIR. The default setting is discard.

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

action: Sets the action to take on the packet:

· discard: Drops the packet.

· pass: Permits the packet to pass through.

Usage guidelines

To use two rates for traffic policing, configure the car command with the pir peak-information-rate option. To use one rate for traffic policing, configure the car command without the pir peak-information-rate option.

A QoS policy that uses a traffic behavior configured with CAR can be applied in either the inbound direction or outbound direction of an interface.

If you execute the car command multiple times in the same traffic behavior, the most recent configuration takes effect.

Only the default action is supported for green packets and yellow packets. The discard and pass actions are supported for red packets.

Examples

# Configure a CAR action in traffic behavior database:

· Set the CIR to 200 kbps, CBS to 51200 bytes, and EBS to 0.

· Transmit the conforming packets, and mark the excess packets with DSCP value 0 and transmit them.

Parameters

access-cgn-vpn vpn-instance vpn-instance-name: Redirects traffic on CGN cards to an MPLS L3VPN instance specified by its name, a case-sensitive string of 1 to 31 characters.

access-vpn: Redirects traffic to an MPLS L3VPN instance.

vpn-instance-name1: Specifies the primary VPN instance by its name, a case-sensitive string of 1 to 31 characters.

vpn-instance-name2: Specifies the backup VPN instance by its name, a case-sensitive string of 1 to 31 characters. If the primary VPN instance does not exist or its associated track entry is in abnormal state, traffic will be redirected to the backup VPN instance.

track track-entry-number: Specifies a track entry by its ID in the range of 1 to 1024. The primary and and backup VPN instances can be associated with the same or different track entries. By specifying track entries, you can associate traffic redirection with detection modules, such as NQA and BFD (see High Availability Configuration Guide).

cpu: Redirects traffic to the CPU.

dhcp-to-cpu: Redirects DHCP packets to the CPU.

failover group group-name: Redirects traffic to a failover group specified by its name, a case-sensitive string of 1 to 63 characters.

http-to-cpu: Redirects HTTP requests to the CPU.

https-to-cpu: Redirects HTTPS requests to the CPU.

interface interface-type interface-number: Redirects traffic to an interface specified by its type and number. To redirect traffic to a tunnel interface, set the interface type to tunnel. To redirect traffic to a Layer 2 aggregate interface, set the interface type to bridge-aggregation. To redirect traffic to a Layer 3 aggregate interface, set the interface type to route-aggregation.

next-hop: Redirects traffic to a next hop. For successful traffic redirection, make sure the next hop IP address is reachable. If both primary and secondary next hop IP addresses are specified, make sure a minimum of one IP address is reachable. The redirection feature periodically looks up the routing table to verify the reachability of next hop IP addresses. If track entries are specified, the redirection feature verifies the reachability of the next hop IP addresses based on the Track detection result. If both primary and secondary next hop IP addresses are unreachable, traffic redirection to a next hop does not take effect.

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the next hop belongs. The vpn-instance-name argument represents the VPN instance name, a case-sensitive string of 1 to 31 characters. If the next hop belongs to the public network, do not specify this option.

ipv4-add1: Specifies the primary next hop IPv4 address. If traffic fails to be redirected to this IPv4 address, the traffic is redirected to the secondary IPv4 address.

ipv4-add2: Specifies the secondary next hop IPv4 address.

ipv6-add1: Specifies the primary next hop IPv6 address. If traffic fails to be redirected to this IPv6 address, the traffic is redirected to the secondary IPv6 address.

ipv6-add2: Specifies the secondary next hop IPv6 address.

track track-entry-number: Specifies a track entry by its ID in the range of 1 to 1024. Different track entries can be specified for primary and secondary IP addresses. By specifying track entries, you can associate traffic redirection with detection modules, such as NQA and BFD (see High Availability Configuration Guide).

slot slot-number: Redirects traffic to a card specified by its slot number. (In standalone mode.)

chassis chassis-number slot slot-number: Redirects traffic to a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (In IRF mode.)

sr-policy endpoint color: Redirects traffic to an SR-MPLS TE policy. The endpoint argument represents the endpoint IPv4 address of the SR-MPLS TE policy. The color argument represents the color attribute value of the SR-MPLS TE policy, in the range of 0 to 4294967295.

srv6-policy endpoint color [ { sid | vpnsid } sid ]: Redirects traffic to an SRv6 TE policy. The endpoint argument represents the endpoint IPv6 address of the SRv6 TE policy. The color argument represents the color attribute value of the SRv6 TE policy, in the range of 0 to 4294967295. The sid sid argument represents the public network SRv6 SID (an IPv6 address) of the egress node. Packets continue to be forwarded in the public network after they are forwarded through the SRv6 TE policy. The vpnsid sid argument represents the private network SRv6 SID (an IPv6 address) of the egress node. Packets continue to be forwarded in the private network after they are forwarded through the SRv6 TE policy. The device adds the SRv6 SID to the SRH header and places it after the SID list. After the packets are forwarded to the egress node, the egress node takes the forwarding action based on the SRv6 SID.

Usage guidelines

If you execute the redirect command multiple times in the same traffic behavior, all configured actions take effect at the same time. Exceptions are that the redirect cpu, redirect http-to-cpu, and redirect https-to-cpu commands are mutually exclusive.

For IPoE Web authentication, you must configure the redirect http-to-cpu or redirect https-to-cpu command. If a user performs IPoE Web authentication through the Web browser but the HTTP request is not destined for the portal Web server, the access device redirects the request to the CPU. The CPU pushes the Web authentication page to the user.

To prevent the CPU from receiving a large number of HTTP requests during IPoE Web authentication, use the ip subscriber http-fast-reply enable command to enable the HTTP request fast reply function. This function reduces the CPU load by identifying HTTP requests in hardware and automatically replying with HTTP responses. For more information about the ip subscriber http-fast-reply enable command, see IPoE commands in see BRAS Services Command Reference.

Only the following cards support redirecting traffic to Layer 3 Ethernet interfaces and loopback interfaces, and these cards do not support redirecting traffic to Layer 3 aggregate interfaces:

SPE	RX-SPE200, RX-SPE200-E

In a CGN deployment, some traffic of internal users needs to be redirected to a VPN instance for monitoring. The redirect access-cgn-vpn vpn-instance command redirects traffic on CGN cards after translation to the output interface bound to a VPN instance according to the routing table of the VPN instance. The redirect access-cgn-vpn vpn-instance command does not take effect on traffic on cards other than CGN cards. The redirect access-cgn-vpn vpn-instance command takes effect only when the QoS policy is applied globally.

You can only redirect traffic to the public network by redirecting the traffic to an SR-MPLS TE policy. You can redirect traffic to the public network or a VPN instance by redirecting the traffic to an SRv6 TE policy. If you do not specify the { sid | vpnsid } sid option, traffic is redirected to the public network.

Make sure the specified SRv6 SID is correct. This value in packets does not indicate the public or private network attribute. The destination node forwards the packets according to the local SID table.

Parameters

account-level: Specifies an accounting level in the range of 1 to 8.

Usage guidelines

If QoS policies that contain accounting level marking actions are applied globally, to an interface, and to a user profile, configure an ITA policy for each accounting level. For information about ITA policies, see AAA in BRAS Services Configuration Guide and BRAS Services Command Reference.

The remark account-level command takes effect only on packets from users that are configured with the same accounting level in an ITA policy.

Do not specify accounting level 1. If you specify accounting level 1, the accounting of ITA traffic will be inaccurate because this accounting level also includes non-ITA traffic.

The remark account-level command takes effect only on packets from users that are configured with the same accounting level in an ITA policy.

remark tunnel-dscp

Use remark tunnel-dscp to configure an outer DSCP marking action in a traffic behavior.

Use undo remark tunnel-dscp to restore the default.

Syntax

remark tunnel-dscp dscp-value

undo remark tunnel-dscp

Default

No outer DSCP marking action is configured.

Views

Traffic behavior view

Predefined user roles

network-admin

Parameters

dscp-value: Specifies the DSCP value to be set for the outer IP header of tunneled packets. The DSCP value can be a number from 0 to 63 or a keyword in Table 6.

Usage guidelines

This command takes effect on the following packets:

· GRE packets.

· VXLAN packets.

· IPv4 over IPv4 tunneled packets.

· IPv6 over IPv4 tunneled packets.

· IPv6 tunneled packets.

· MPLS TE tunneled packets.

The outer DSCP value marking action takes effect only when the QoS policy is applied to an interface or globally.

The remark tunnel-dscp command is mutually exclusive with the remark dscp or remark ip-precedence command in one traffic behavior.

If you execute the remark tunnel-dscp command multiple times in the same traffic behavior, the most recent configuration takes effect.

This command is available only for the following cards:

Card category	Cards
CEPC	CEPC-XP4LX, CEPC-XP24LX, CEPC-XP48RX, CEPC-CP4RX, CEPC-CP4RXA, CEPC-CP4RX-L, CEPC-CQ8L, CEPC-CQ8LA, CEPC-CQ8L1A, CEPC-CQ16L1
CSPEX	CSPEX-1304X, CSPEX-1404X, CSPEX-1502X, CSPEX-1504X, CSPEX-1504XA, CSPEX-1602X, CSPEX-1602XA, CSPEX-1804X, CSPEX-1512X, CSPEX-1612X, CSPEX-1812X, CSPEX-1802X, CSPEX-1802XA, CSPEX-2612XA, CSPEX-1812X-E, CSPEX-2304X-G, CSPEX-1502XA
SPE	RX-SPE200, RX-SPE200-E

The remark tunnel-dscp command does not take effect on multicast or broadcast traffic transmitted over a tunnel.

Predefined user roles

network-admin

Parameters

behavior-name: Specifies a name for the traffic behavior, a case-sensitive string of 1 to 31 characters.

Usage guidelines

You can configure multiple actions in a traffic behavior. All actions in a traffic behavior will be taken on matching packets if they do not conflict.

Examples

# Create a traffic behavior named behavior1.

<Sysname> system-view

[Sysname] traffic behavior behavior1

[Sysname-behavior-behavior1]

classifier behavior

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

Use undo classifier to delete a class-behavior association from a QoS policy.

Syntax

classifier classifier-name behavior behavior-name [ [ mode qppb-manipulation | insert-before before-classifier-name ] *insert-before before-classifier-name ] *

undo classifier classifier-name

Default

No traffic behavior is associated with a traffic class.

Views

QoS policy view

Predefined user roles

network-admin

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.

mode qppb-manipulation: Specifies that the class-behavior association applies only to QPPB. The if-match qos-local-id command in the class sets the same local QoS ID as the apply qos-local-id command in the BGP routing policy. For more information about routing policies, see Layer 3—IP Routing Configuration Guide.

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.

You can configure multiple class-behavior associations in a QoS policy. The class-behavior associations are matched in their configuration order. When a match is found, the match process stops and the actions in the matching class-behavior association are taken.

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

On the following cards, the mode qppb-manipulation keyword does not support matching the IP precedence in a BGP routing policy:

Card category	Cards
CEPC	CEPC-CQ8L, CEPC-CQ8LA, CEPC-CQ8L1A, CEPC-CQ16L1
CSPEX	CSPEX-1802X, CSPEX-1802XA, CSPEX-2612XA, CSPEX-1812X-E, CSPEX-2304X-G, CSPEX-1502XA
SPE	RX-SPE200-E

This keyword supports matching the local QoS ID and other match criteria.

Examples

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

<Sysname> system-view

[Sysname] qos policy user1

[Sysname-qospolicy-user1] classifier database behavior test

# Associate traffic class database with traffic behavior test in QoS policy user1, and specify that the class-behavior association applies only to QPPB.

qos apply policy (interface view, control plane view)

Use qos apply policy to apply a QoS policy to an interface or control plane.

Use undo qos apply policy to remove an applied QoS policy.

Syntax

qos apply policy policy-name { inbound | outbound } [ preorder preorder-value ] [ share-mode | share-mode-both ]

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

Default

No QoS policy is applied.

Views

Control plane view

Interface view

Predefined user roles

network-admin

Parameters

policy-name: Specifies a QoS policy by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a QoS policy when executing the undo qos apply policy command on an interface, all applied QoS policies will be removed from the interface. You must specify a QoS policy when executing the undo qos apply policy command on any other object.

inbound: Applies the QoS policy to the inbound direction.

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

preorder preorder-value: Specifies the order in which QoS policies applied to the inbound direction of an interface are executed. The greater the value, the higher the priority. The value for the preorder-value argument can only be 1. This option is supported only in interface view.

share-mode: Applies the QoS policy in sharing mode to a Layer 2 or Layer 3 Ethernet interface. In this mode, all interfaces on an interface card with the same QoS policy applied in one direction share one QoS and ACL resource.

share-mode-both: Applies the QoS policy in direction-independent sharing mode to a Layer 2 or Layer 3 Ethernet interface. In this mode, all interfaces on an interface card with the same QoS policy applied share one QoS and ACL resource.

Usage guidelines

In a vBRAS CP and UP separation (CUPS) system, a QoS policy applied to a VSI interface does not take effect. You must apply the QoS policy to the interface that acts as an AC.

An inbound QoS policy cannot contain any of these queuing actions: queue ef, queue af, or queue wfq.

Only the following cards support applying a QoS policy to the inbound direction of a tunnel interface:

Card category	Cards
CEPC	CEPC-CQ8L, CEPC-CQ8LA, CEPC-CQ8L1A, CEPC-CQ16L1
CSPEX	CSPEX-1802X, CSPEX-1802XA, CSPEX-2612XA, CSPEX-1812X-E, CSPEX-2304X-G, CSPEX-1502XA
SPE	RX-SPE200-E

If you apply QoS policies separately to an aggregate interface and a member port of the aggregate interface, the QoS policy applied to the aggregate interface takes effect. The QoS policy applied to the member port takes effect after it leaves the aggregation group.

In a vBRAS CP and UP separation (CUPS) system, a QoS policy applied to a VSI interface does not take effect. You must apply the QoS policy to the interface that acts as an AC.

You can specify the preorder preorder-value option only when you apply a QoS policy to the inbound direction of an interface.

A QoS policy applied with the preorder preorder-value option specified has higher priority than that applied without the preorder preorder-value option.

A QoS policy configured with CBQ is not supported in control plane view.

You can use the following commands to match protocol packets sent to the CPU for a QoS policy applied to a control plane:

· if-match control-plane protocol

· if-match acl

When you use the if-match acl command to match protocol packets sent to the CPU, follow these restrictions and guidelines:

¡ The used ACL must be an advanced ACL.

¡ You must specify TCP or UDP for the protocol argument in the rule.

¡ You must specify a source port or destination port by using the eq operator in the rule.

For example, an IPv4 advanced ACL that contains a rule permit tcp source-port eq 80 statement can match TCP packets sent to the CPU.

If you specify the share-mode or share-mode-both keyword when applying a QoS policy to an interface, follow these restrictions and guidelines:

· If you specify the share-mode keyword, all interfaces on an interface module with the QoS policy applied in one direction share one QoS and ACL resource. If you specify the share-mode-both keyword, all interfaces on an interface module with the QoS policy applied share one QoS and ACL resource.

If the share-mode or share-mode-both keyword is not specified, each interface uses one QoS and ACL resource in one direction.

· All interfaces that share one QoS and ACL resource evenly share the set CIR if a traffic policing action is configured in the QoS policy.

If the share-mode or share-mode-both keyword is not specified, the bandwidth of each interface can be limited to the CIR.

· You cannot specify the share-mode or share-mode-both keyword when applying an ACL to the same direction of the interface. For more information about applying an ACL to an interface, see the packet-filter (interface view) command in ACL commands.

The display qos policy interface command output for an interface also contains packet statistics for all interfaces that share the QoS and ACL resource with the interface.

You cannot change the sharing mode dynamically after a QoS policy is applied to an interface. To change the sharing mode for an applied QoS policy, perform the following tasks:

1. Remove the QoS policy from the interface.

2. Reapply the QoS policy with or without the share-mode or share-mode-both keyword specified.

Parameters

bandwidth-value: Specifies the exclusive bandwidth value in kbps. The value range for this argument is:

· 300 to 950000 for GE interfaces.

· 300 to 9500000 for 10-GE interfaces.

· 300 to 95000000 for 100-GE interfaces.

· 300 to 95000000 for Layer 3 aggregate interfaces.

Usage guidelines

The exclusive bandwidth on an interface is reserved for specific features and cannot be shared with other features. The amount of exclusive bandwidth is deducted from the interface bandwidth. For example, if you set the exclusive bandwidth for CRLSP, the exclusive bandwidth can only be used by CRLSP. For more information about the CRLSP exclusive bandwidth, see static CRLSP configuration in MPLS Configuration Guide.

The exclusive bandwidth feature is mutually exclusive with the HQoS feature. If one feature has been configured on an interface, the other feature cannot be configured successfully.

· 2500 to 95000000 for 100-GE interfaces.

· 300 to 95000000 for Layer 3 aggregate interfaces.

Usage guidelines

By default, all subinterfaces of a main interface share and contend for the bandwidth of the main interface. Subinterfaces that carry key services cannot be guaranteed enough bandwidth. This feature allows subinterfaces of a physical interface or aggregate interface to exclusively use the specified amount of bandwidth.

Before configuring the channelized bandwidth for a Layer 3 aggregate subinterface, you must execute the bandwidth command on the aggregate interface.

The total channelized bandwidth of subinterfaces cannot exceed the actual bandwidth of the main interface plus 1 Mbps. The channelized bandwidth takes effect only in the outbound direction.

This feature is mutually exclusive with the exclusive bandwidth setting.

This feature is mutually exclusive with configuring the maximum reservable bandwidth for MPLS TE. For more information about configuring the maximum reservable bandwidth for MPLS TE, see MPLS TE configuration in MPLS Configuration Guide.

This feature is mutually exclusive with HQoS. For more information about HQoS, see ACL and QoS Configuration Guide.

Parameters

auto: Uses the priority in incoming packets for priority mapping. For Layer 2 packets, the 802.1p priority is used. For Layer 3 packets, the IP precedence is used. For MPLS packets, the EXP value is used.

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

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

exp: Uses the EXP value in incoming MPLS packets for priority mapping.

inner-dot1p: Uses the 802.1p priority in the inner header of received QinQ packets for mapping.

override: Uses the priority derived through priority mapping to overwrite the original priority carried in the packet. This keyword is optional. By default, this feature is disabled.

Usage guidelines

The dot1p, dscp, and inner-dot1p keywords are available only for the following cards:

Card category	Cards
CEPC	CEPC-XP4LX, CEPC-XP24LX, CEPC-XP48RX, CEPC-CP4RX, CEPC-CP4RXA, CEPC-CP4RX-L, CEPC-CQ8L, CEPC-CQ8LA, CEPC-CQ8L1A, CEPC-CQ16L1

SPE	RX-SPE200, RX-SPE200-E

If you do not specify the override keyword, the device obtains the EXP value through priority mapping when an IP packet enters an MPLS network.

For Layer 3 packets, the outer 802.1p priority value is overwritten according to the priority trust mode, regardless of whether the override keyword is specified.

The qos trust dot1p or qos trust dscp command does not take effect on MPLS packets from the public network. The device uses the EXP value in the MPLS packets for priority mapping.

The exp keyword is available only for the L2VE interfaces and L3VE interfaces on the following cards::

Parameters

any: Performs CAR for all control plane traffic.

user: Performs CAR for the control plane traffic from all online users.

cir committed-information-rate: Specifies the CIR in kbps. The committed-information-rate argument has the following value ranges:

· 8 to 300000000 for traffic policing for all control plane traffic. Only the range 8 to 1000000 is supported in the current software version.

· 8 to 300000000 for online user-based traffic policing.

· 8 to 300000000 for whitelist-based traffic policing. Only the range 8 to 100000 is supported in the current software version.

cbs committed-burst-size: Specifies the CBS in the range of 512 to 256000000 bytes. The default is the product of 62.5 and the CIR value.

ebs excess-burst-size: Specifies the EBS in the range of 0 to 256000000 bytes. The default is the product of 62.5 and the PIR value..

pir peak-information-rate: Specifies the PIR in kbps. The peak-information-rate argument has the following value ranges:

· 8 to 300000000 for traffic policing for all control plane traffic. Only the range 8 to 1000000 is supported in the current software version.

· 8 to 300000000 for online user-based traffic policing.

Usage guidelines

To use two rates for traffic policing, configure the qos car command with the pir peak-information-rate option. To use one rate for traffic policing, configure the qos car command without the pir peak-information-rate option.

For online user-based traffic policing, the CIR is the rate of control plane traffic from each online user.

Use undo qos member-link-scheduler distribute to restore the default.

Syntax

Views

Layer 3 aggregate interface view

Predefined user roles

network-admin

Parameters

user-profile-car: Specify Layer 3 aggregate interfaces that are applied with user profiles containing traffic policing settings.

Usage guidelines

If you apply a user profile containing traffic policing settings to a Layer 3 aggregate interface, the member ports of the aggregate interface are rate limited by default as follows:

· If all member ports belong to one chip, the total traffic rate on them cannot exceed the rate limit configured for the aggregate interface.

· If the member ports belong to different chips, member ports on one chip cannot exceed the rate limit configured for the aggregate interface. In this case, the total traffic rate on all member ports can exceed the rate limit configured for the aggregate interface.

This feature limits the traffic rates on the member ports based on their physical bandwidth when all member ports belong to different chips, making sure the total traffic rate on them cannot exceed the rate limit configured for the aggregate interface. Suppose you apply a user profile with a rate limit of 100 Mbps to a Layer 3 aggregate interface, and the aggregate interface contains four member ports (ports A, B, C, and D) that have 1 Gbps bandwidth. If member ports A and B belong to chip 1, member port C belongs to chip 2, and member port D belongs to chip 3:

· The total traffic rate on member ports A and B can reach 50 Mbps.

· The traffic rate on member port C can reach 25 Mbps.

· The traffic rate on member port D can reach 25 Mbps.

You can view the rate limit value for each member port by using the display qos user-profile-car member-link-scheduler distribute command.

This command also takes effect on Layer 3 aggregate interfaces applied with CAR policies.

This feature takes effect on both the inbound and outbound directions of Layer 3 aggregate interfaces.

Views

System view

Predefined user roles

network-admin

Usage guidelines

For interface CAR and MQC CAR, the device calculates the packet length based on the data link layer frame by default.

· Execute this command when the packets processed by the device are short. Short packets require accurate traffic policing, and the interframe gap will affect the accuracy of traffic policing. This command allows the device to include a 20-byte interframe gap (excluding the CRC field) in calculating the packet length.

· Do not execute this command when the packets processed by the device are long. This behavior saves the compute resources of the device.

This command takes effect only on Layer 3 Ethernet interfaces and Layer 3 aggregate interfaces.

This command does not take effect if the mirroring-group car command is executed.

A queue with a weight of 0 cannot be configured with the minimum guaranteed bandwidth and has the lowest priority. Queues with a weight of 0 are scheduled in a round robin manner.

If a large CIR (for example, 30 Gbps) is configured in a traffic policing action or rate limit on a 100-GE interface, configure the weights as multiples of 10 in this command as a best practice. The weight values affect the granularity of bandwidth allocation during queue scheduling. The device cannot correctly allocate bandwidth to queues on an interface according to small weight values.

# Create a queue scheduling profile named myprofile, and configure queue 0 to use SP.

<Sysname> system-view

[Sysname] qos qmprofile myprofile

qos reserved-bandwidth

Use qos reserved-bandwidth to set the maximum reserved bandwidth as a percentage of available bandwidth on an interface or PVC.

Use undo qos reserved-bandwidth to restore the default.

Syntax

qos reserved-bandwidth pct percent

undo qos reserved-bandwidth

Default

The maximum reserved bandwidth is 80% of available bandwidth on an interface or PVC.

Views

Interface view

Predefined user roles

network-admin

Parameters

percent: Specifies the percentage of available bandwidth to be reserved. The value range for this argument is 1 to 100.

Usage guidelines

The maximum reserved bandwidth is set on a per-interface or per-PVC basis. It decides the maximum bandwidth assignable for the QoS queues on an interface or PVC. It is typically set no greater than 80% of available bandwidth, considering the bandwidth for control traffic and Layer 2 frame headers.

Use the default maximum reserved bandwidth setting in most situations. If you adjust the setting, make sure the Layer 2 frame header plus the data traffic is under the maximum available bandwidth of the interface.

The maximum available bandwidth of an interface can be set by using the bandwidth command. For more information about this command, see Interface Command Reference.

If you execute the qos reserved-bandwidth pct command multiple times, the most recent configuration takes effect.

Examples

# Set the maximum reserved bandwidth to 70% of available bandwidth on Ten-GigabitEthernet 3/1/1.

<Sysname> system-view

queue af

Use queue af to enable assured-forwarding (AF) and set the minimum guaranteed bandwidth for AF.

Use undo queue af to restore the default.

Syntax

queue af bandwidth { bandwidth [ pir peak-information-rate ] | pct percentage }

undo queue af

Default

AF is not configured.

Views

Traffic behavior view

Predefined user roles

network-admin

Parameters

bandwidth: Specifies the minimum guaranteed bandwidth in the range of 64 to 300000000 kbps.

pir peak-information-rate: Specifies the PIR in the range of 64 to 300000000 kbps.

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

Usage guidelines

If you specify the pct percentage option, the actual minimum guaranteed bandwidth is the maximum reserved bandwidth (configured by using the qos reserved-bandwidth command) multiplied by this option.

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 this command multiple times in the same traffic behavior, the most recent configuration takes effect.

You cannot configure the queue af command together with the queue ef or queue wfq command in the same traffic behavior.

If you execute this command multiple times in the same traffic behavior, the most recent configuration takes effect.

Traffic behavior view

Predefined user roles

network-admin

Parameters

bandwidth: Specifies the maximum bandwidth in the range of 64 to 300000000 kbps.

cbs burst: Specifies the CBS in the range of 1600 to 1000000000 bytes. The default is the bandwidth value multiplied by 25. To accommodate bursts, you must set the CBS to be greater than the amount of traffic transmitted at the bandwidth over 50 milliseconds.

pir peak-information-rate: Specifies the PIR in the range of 64 to 300000000 kbps.

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

If you specify the pct percentage option, the actual maximum bandwidth is the maximum reserved bandwidth (configured by using the qos reserved-bandwidth command) multiplied by this option.

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, in kbps or in percentage.

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

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

This command and the queue af command are mutually exclusive in one traffic behavior.

If you execute this command multiple times in the same traffic behavior, the most recent configuration takes effect.

Parameters

weight-value: Specifies the weight value in the range of 1 to 63.

Usage guidelines

The following traffic is scheduled by using WFQ:

· Traffic between the minimum guaranteed bandwidth and PIR.

· Traffic between the maximum bandwidth and PIR.

If you execute this command multiple times in the same traffic behavior, the most recent configuration takes effect.

For POS interfaces and Ethernet interfaces on a CSPEX-1204 card, the AF traffic exceeding its minimum guaranteed bandwidth, EF traffic exceeding its guaranteed bandwidth, and BE traffic are scheduled according to the WFQ weights. For other interface types and subinterfaces on a CSPEX-1204 card, the following traffic types are in descending order of priority:

· EF traffic within the guaranteed bandwidth.

· AF traffic within the minimum guaranteed bandwidth.

· AF traffic exceeding the minimum guaranteed bandwidth.

· BE traffic.

· EF traffic exceeding the guaranteed bandwidth.

Examples

# Configure traffic behavior database as follows:

· Enable AF, and set the minimum guaranteed bandwidth to 200 kbps and the PIR to 500 kbps.

· Set the WFQ weight to 100 for traffic between 200 kbps and 500 kbps.

network-admin

Parameters

all: Specifies all queues.

queue-id: Specifies a queue by its ID in the range of 0 to 7.

drop-level drop-level: Specifies a drop level. This argument is a consideration for dropping packets. The value 0 corresponds to green packets, the value 1 corresponds to yellow packets, and the value 2 corresponds to red packets. If you do not specify a drop level, the subsequent configuration takes effect on the packets in the queue regardless of the drop level.

low-limit low-limit: Specifies the lower limit for the average queue length in the range of 0 to 29296875 packets.

high-limit high-limit: Specifies the lower limit for the average queue length in the range of 0 to 29296875 packets. The upper limit must be greater than the lower limit. The upper limit should not be greater than 12582912.

discard-probability discard-prob: Specifies the drop probability in percentage, in the range of 0 to 100. When the average queue size is between the lower limit and the upper limit, packets are dropped according to this drop probability. This option is not supported on CSPEX-1204 cards.

Usage guidelines

When the average queue size is smaller than the lower threshold, no packet is dropped. When the average queue size is between the lower threshold and the upper threshold, the packets are dropped at random. The longer the queue is, the higher the drop probability is. When the average queue size exceeds the upper threshold, subsequent packets are dropped.

To use the tail drop mechanism for a queue, set the same value for the lower limit and upper limit and set the drop probability to 100%.

Examples

# In queue-based WRED table queue-table1, configure the following drop-related parameters for packets in queue 1:

· The drop level is 1.

· The lower limit for the average queue length is 10.

· The upper limit for the average queue length is 20.

· The drop probability is 30%.

Parameters

limit-percent: Specifies the upper limit and lower limit for the average queue length in percentage. If you do not specify this keyword, the upper limit and lower limit for the average queue length are specified in absolute value.

low-limit low-limit: Specifies the lower limit for the average queue length.

· If you specify the limit-percent keyword, the value range is 1 to 100 in % The lower limit for the average queue length is low-limit × queue length.

· If you do not specify the limit-percent keyword, the value range for low-limit is 0 to 29296875 packets.

high-limit high-limit: Specifies the upper limit for the average queue length.

· If you specify the limit-percent keyword, the value range is 1 to 100 in % The upper limit for the average queue length is high-limit × queue length.

· If you do not specify the limit-percent keyword, the value range for high-limit is 0 to 29296875 packets.

discard-probability discard-prob: Specifies the drop probability. The value range for discard-prob is 0 to 100 in percenrtage. CSPEX-1204 cards do not support this option.

queue-length length: Specifies the queue length. The value range for length is 0 to 29296875.

Usage guidelines

When the queue size is shorter than the lower threshold, no packet is dropped. When the queue size is between the lower threshold and the upper threshold, the received packets are dropped at random. The drop probability in a queue increases along with the queue size under the maximum drop probability. When the queue size reaches the upper threshold, all subsequent packets are dropped.

For packets with the same drop level, the upper limit and lower limit for the average queue length must be configured in the same unit, either percentage or absolute value.

If you do not specify a drop level, this command is issued to each drop level, and three configuration entries are generated on the device.

You can specify the queue length either by the queue-length length option in this command or the queue length command. You need to specify the queue length only when you configure the upper threshold and lower threshold for the average queue length in percentage. Otherwise, the command will fail to be issued.

Examples

# Configure the following WRED parameters for packets with drop level 1 in WRED profile queue-profile1: lower limit 10, upper limit 20, and drop probability 30.

When the number of dropped packets reaches a set threshold during the set interval, the system generates and sends logs to the information center. For information about configuring the information center, see Network Management and Monitoring Configuration Guide.

If you enable packet-drop logging for traffic matching the IPv4 dynamic whitelist, the device automatically enables packet-drop logging for protocol traffic sent to the CPU.

Examples

# (In IRF mode.) Enables packet-drop logging for traffic matching the QoS policy applied to the control plane of slot 1.

logging packet-drop interval

Use logging packet-drop interval to set the interval for sending packet-drop logs.

Use undo logging packet-drop interval to restore the default.

Syntax

logging packet-drop { user-defined-flow | whitelist } interval interval-value

undo logging packet-drop { user-defined-flow | whitelist } [ interval ]

Default

The interval for sending packet-drop logs is 600 seconds.

Parameters

user-defined-flow: Enables packet-drop logging for traffic matching the QoS policy applied to the control plane.

whitelist: Enables packet-drop logging for traffic matching the IPv4 dynamic whitelist.

interval-value: Specifies the interval for sending packet-drop logs. The value range for this argument is 60 to 3600 seconds.

Usage guidelines

If you specify the interval keyword when executing the undo form of this command, only the interval is restored to the default value. If you do not specify the interval keyword, both the interval and the packet thresholds are restored to the default values.

Examples

# (In IRF mode.) Set the interval for sending packet-drop logs to 600 seconds for traffic matching the QoS policy applied to the control plane of slot 1.

<Sysname> system-view

[Sysname] control-plane slot 1

[Sysname-cp-slot1] logging packet-drop user-defined-flow interval 600

logging packet-drop enable

logging packet-drop { count-threshold | rate-threshold } *

Use logging packet-drop { count-threshold | rate-threshold } * to set the packet thresholds for sending packet-drop logs.

Use undo logging packet-drop to restore the default.

Syntax

logging packet-drop { user-defined-flow | whitelist } { count-threshold count-threshold-value | rate-threshold rate-threshold-value } *

undo logging packet-drop { user-defined-flow | whitelist } [ count-threshold | rate-threshold ]

Default

The packet count threshold and packet rate threshold for sending packet-drop logs are 30000 packets and 50 packets per minute, respectively.

Parameters

user-defined-flow: Enables packet-drop logging for traffic matching the QoS policy applied to the control plane.

whitelist: Enables packet-drop logging for traffic matching the IPv4 dynamic whitelist.

count-threshold count-threshold-value: Specifies the maximum number of dropped packets for sending packet-drop logs. The value range for the count-threshold-value argument is 1 to 1000000.

rate-threshold rate-threshold-value: Specifies the maximum number of packets dropped per minute for sending packet-drop logs. The value range for the rate-threshold-value argument is 0 to 1000000.

Usage guidelines

If you specify a keyword when executing the undo form of this command, only the related parameter is restored to the default value. If you do not specify the interval keyword, both the interval and the packet thresholds are restored to the default values.

Examples

# (In IRF mode.) Set the maximum number of packets dropped per minute to 100 seconds for slot 1.

<Sysname> system-view

[Sysname] control-plane slot 1
