· Application quality probe—For specific service flows forwarded through the SDWAN tunnels, RIR-SDWAN detects the quality of the application flows with the specified packet signatures for application analysis.

Application quality probe settings must be configured in application quality probe view.

If application quality probing is enabled, the device does not support the per-packet load balancing mode.

Examples

# Enter application quality probe view.

Usage guidelines

To avoid NQA probes from occupying too many resources on a hub in a hub-spoke network, configure the hub as an RIR server and configure the spokes as RIR clients.

You can enable the RIR client globally or on an interface.

· Enabling the RIR client globally also enables the RIR client for all interfaces on the device. The interfaces can send link quality probe results for the RIR client.

· Enabling the RIR client on an interface allows only that interface to send link quality probe results for the RIR client.

When you enable the RIR client, follow these restrictions and guidelines:

· In a VXLAN network, only tunnel interfaces support enabling the RIR client. The RIR client uses the tunnel interfaces to send link quality probe results.

· The RIR server and RIR client cannot be both enabled on the same interface.

· If the enabled role (RIR server or client) on an interface is different from the globally enabled role, the interface-specific role takes effect on that interface.

Parameters

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance on which the local and peer devices establish RIR collaboration relationship. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. The specified VPN instance must exist. If the local and peer IP addresses belong to the public network, do not specify this option.

peer-ipv4-address: Specifies an RIR collaboration peer by its IPv4 address.

local-ipv4-address: Specifies the IPv4 address of the local device. The local and peer devices must both belong to the public network or the same VPN instance.

sync-port port-number: Specifies the TCP port number used by the local and peer devices to synchronize link data. The value range for the port-number argument is 1024 to 65535. Make sure the port number is not used by any other service on the device.

Usage guidelines

Each pair of devices in an RIR collaboration device group must establish RIR collaboration relationship. You must configure this command on both the local and peer devices.

In a pair of devices with RIR collaboration relationship, the device with a lower IP address is the client. The client uses the port number specified by using this command to initiate a TCP connection request to its peer. Through the TCP connection, the local device can synchronize the configuration and status data of links that meet the service requirements to the peer device. The data does not include link data synchronized from other devices in the same RIR collaboration device group.

For the local device to select links from a peer device, you must execute the collaboration peer redirect command on both the local and peer devices.

The local and peer devices must use the same TCP port number for link data synchronization. A device can use the same or different TCP port numbers to synchronize data to different peers.

If you execute this command multiple times for the same pair of devices in the public network or a VPN instance, the most recent configuration takes effect.

Examples

# Establish RIR collaboration relationship between local device 1.1.1.1 and peer device 1.1.1.2 on the public network. They use TCP port number 6000 for link data synchronization.

<Sysname> system-view

[Sysname] rir

Parameters

vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance on which the local and peer devices establish RIR collaboration relationship. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the local and peer devices establish RIR collaboration relationship on the public network, do not specify this option.

peer-ipv4-address: Specifies an RIR collaboration peer by its IPv4 address.

vpn-instance redirect-vpn-instance-name: Specifies the MPLS L3VPN instance for the packets to be redirected to the redirect IPv4 address of the peer device. The redirect-vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the packets to be redirected belong to the public network, do not specify this option.

redirect-ipv4-address: Specifies the redirect IPv4 address of the peer device.

Usage guidelines

Use this command on both the local and peer devices that have established RIR collaboration relationship. This command specifies the redirect IP address for packets redirected to a peer device on the public network or a VPN instance. When the local device selects links from the peer device to forward packets on the public network or a VPN instance, it performs the following operations:

· Looks up the routing table of the public network or VPN instance based on the redirect IP address.

· Forwards the packets to the peer device through the RIR dedicated link.

If you execute the undo form of this command without the vpn-instance redirect-vpn-instance-name option for a peer, the redirect IPv4 address of the public network is deleted for the peer.

If you execute this command multiple times for the same peer on the public network or in the same redirect VPN instance, the most recent configuration takes effect.

Examples

# Specify 2.1.1.1 as the redirect IP address in VPN instance b for peer device 1.1.1.2 in VPN instance a.

Parameters

delay delay-weight: Sets the weight for the delay metric used for computing CQI values, in the range of 0 to 10.

jitter jitter-weight: Sets the weight for the jitter metric used for computing CQI values, in the range of 0 to 10.

packet-loss packet-loss-weight: Sets the weight for the packet loss metric used for computing CQI values, in the range of 0 to 10.

Usage guidelines

RIR-SDWAN computes Comprehensive Quality Indicator (CQI) values to evaluate link quality.

· If the probe result of a metric (delay, jitter, or packet loss rate) is lower than or equal to the associated quality threshold in the SLA, the CQI value for the metric is 100.

· If the probe result of a metric is higher than the associated quality threshold in the SLA, the CQI value for the metric is calculated with the formula: (metric threshold × 100) / probe result of the metric.

· The overall CQI value is calculated with the formula: (x × Ds+ y × Js + z × Ls) / (x + y + z).

In this formula, x, y, and z represent the weight values of delay, jitter, and packet loss rate, respectively. Ds, Js, and Ls represent the CQI values for delay, jitter, and packet loss rate, respectively.

To avoid frequent link switchovers, the device uses the approximate overall CQI value to evaluate link quality. The approximate overall CQI value is a multiple of 5 that is smaller than and closest to the overall CQI value. For example, if the overall CQI value is 82.5, the approximate overall CQI value is 80.

For quality tolerant link selection, the device selects the link with the highest approximate overall CQI value as the optimal link. If multiple links have the highest approximate overall CQI value, the device selects one or multiple optimal links from them based on the link load balancing mode.

The weights for the delay, jitter, and packet loss metrics cannot be all 0.

Examples

# Configure the weight values for the delay, jitter, and packet loss metrics as 2, 5, and 7, respectively, to compute CQI values for link quality evaluation of flow 1.

Parameters

threshold-value: Sets the link delay threshold, in the range of 10 to 60000 milliseconds.

Usage guidelines

Link delay refers to the interval between the sending time and receiving time of a packet.

The shorter the delay time, the higher the link quality.

A flow template uses the link delay threshold in its associated SLA to filter links that meet the link delay requirement.

Parameters

bandwidth: Specifies the bandwidth in kbps, in the range of 1 to 400000000.

Usage guidelines

The per-session expected bandwidth configured by using this command is not the actual bandwidth used by a session. It is only a value estimated based on user services.

When the device selects links for traffic of a session, it obtains the per-session expected bandwidth in real time, and performs bandwidth detection based on the obtained bandwidth. If the device fails to obtain the bandwidth, it performs bandwidth detection based on the per-session expected bandwidth in the flow template to which the session belongs. A link is qualified in the bandwidth detection if it meets the following requirements:

· For the link-attached physical output interface, the used bandwidth plus the per-session expected bandwidth is less than 80% of the total bandwidth.

· For the link, the used bandwidth plus the per-session expected bandwidth is less than 80% of the total bandwidth.

Only RIR-SDWAN supports obtaining the per-session expected bandwidth in real time. RIR-VXLAN supports only configuring the per-session expected bandwidth in flow template view.

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

Parameters

flow-id: Specifies a flow ID for the flow template. The flow ID is in the range of 1 to 65535.

Usage guidelines

Use a flow template to define link selection policies (including the quality policy and link preference) that can filter qualified links for a type of service flow. After the device identifies the service of a packet based on the quintuple and DSCP of the packet, it assigns a flow ID to the packet according to the QoS policy applied to the service. Then, RIR selects a qualified link for the packet based on the link selection policies of the flow template that uses the flow ID.

Parameters

upper upper-threshold: Sets the bandwidth usage upper threshold in percentage, in the range of 1 to 100. The upper threshold must be greater than or equal to the lower threshold.

lower lower-threshold: Sets the bandwidth usage lower threshold in percentage, in the range of 1 to 100.

Usage guidelines

If flow priority-based traffic scheduling is enabled, traffic scheduling is triggered when the bandwidth usage of a link-attached physical output interface exceeds the upper threshold. The scheduling might be last for several scheduling periods. Within each scheduling period, RIR redistributes the current lowest priority flow on this link to other links. The scheduling stops for a link in one of the following conditions:

· The bandwidth usage of all link-attached physical output interfaces for the current lowest priority flow is below the lower threshold.

· Only the highest priority flow is left on this link.

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

Usage guidelines

To ensure that services with higher priority preferentially use link resources, enable flow priority-based traffic scheduling.

The priority of a flow that matches a flow template is determined by the ID of the SLA associated with that flow template. The greater the SLA ID, the higher the flow priority. To specify an SLA for a flow template, use the quality-policy command. If the command is not configured in a flow template, flows that match the flow template have the lowest priority.

· The bandwidth usage of all link-attached physical output interfaces for the current lowest priority flow is below the lower threshold.

· Only the highest priority flow is left on this link.

Parameters

delay: Sets the link selection delay in seconds, in the range of 1 to 65535.

Usage guidelines

To improve packet forwarding efficiency, the device does not repeatedly perform link selection for traffic of the same session. After the device performs link selection for traffic of a session, it forwards the subsequent traffic of that session according to the previous link selection result. Link reselection is triggered when any link in the session's flow template has one of the following changes:

· The quality of a link becomes qualified from unqualified or the quality of a link becomes unqualified from qualified.

· The bandwidth usage of a link has reached 90% of the maximum bandwidth.

· The bandwidth usage of a link-attached physical output interface has reached 90% of the maximum bandwidth.

To avoid frequent link selection caused by link flapping, RIR defines a link selection delay and link selection suppression period.

After the device performs link selection, it starts the link selection suppression period if the period has been configured. Within the link selection suppression period, the device does not perform link reselection, but it maintains the link state data. When the link selection suppression period ends, the link selection delay timer starts. If the link state still meets the conditions that can trigger link reselection when the delay timer expires, the device performs link reselection. If the link state changes to not meet the conditions that can trigger link reselection within the delay time, the device does not perform link reselection.

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

Examples

# Set the link selection delay to 30 seconds for RIR-VXLAN.

Parameters

period-value: Sets the link selection suppression period in seconds, in the range of 1 to 131070.

Usage guidelines

To avoid frequent link selection caused by link flapping, configure a link selection suppression period. The device starts the link selection suppression period after it performs a link selection.

Within the link selection suppression period, the device does not perform link reselection, but it maintains the link state data. When the link selection suppression period ends, the link selection delay timer starts. If the link state still meets the conditions that can trigger link reselection when the delay timer expires, the device performs link reselection. If the link state changes to not meet the conditions that can trigger link reselection within the delay time, the device does not perform link reselection.

As a best practice, set the link selection suppression period to a multiple of the link selection delay time. Make sure the suppression period is at least double of the link selection delay time.

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

Usage guidelines

Based on link bandwidth, RIR supports the following link load balancing modes:

· Per-session weight-based link selection mode—RIR global link load balancing mode that takes effect on all RIR flows. This mode can distribute the sessions that match the same flow template to different links according to the weights of the links. RIR selects only one link to transmit a session.

· Per-session periodic link adjustment mode—RIR global link load balancing mode that takes effect on all RIR flows. This mode not only can distribute the sessions that match the same flow template to different links, but also can periodically adjust links for the sessions. Within one adjustment period, RIR selects only one link to transmit a session.

· Per-packet mode—Flow-specific link load balancing mode that takes effect only on sessions that match the flow template where this mode is enabled. This mode can distribute the same session to different links for transmission.

The mechanisms of the per-packet mode are as follows:

· For preference-based primary link selection, preference-based backup link selection, and quality tolerant link selection—If multiple links are available (or multiple links have the highest approximate overall CQI value for quality tolerant link selection in RIR-SDWAN), all these links are candidate optimal links for this session. When forwarding traffic for the session, the device distributes the traffic to these links packet by packet. The probability that a link is selected is calculated by using the following formula: (remaining bandwidth of the link-attached physical output interface / remaining bandwidth sum of all available link-attached physical output interfaces) × (remaining bandwidth of the link / remaining bandwidth sum of all available links for the link-attached physical output interface). The used bandwidth of a link or a physical output interface includes the per-session expected bandwidth.

· For bandwidth tolerant link selection—If multiple links are available for a session, all these links are candidate optimal links for this session. When forwarding traffic for the session, the device distributes the traffic to these links packet by packet. Each link has the same probability to be selected.

Because packets of the same session are distributed to multiple links, the receiver might receive out-of-order packets. As a best practice, do not enable per-packet load balancing for order-sensitive services (except the services that use protocols to maintain a correct packet order, for example, TCP).

If Wide Area Application Services (WAAS) log packet compression or decompression is enabled, per-packet load balancing cannot be performed correctly. For more information about WAAS log packet compression and decompression, see WAAS configuration in Layer 3—IP Services Configuration Guide.

RIR reselect links for sessions that match a flow template if the links in the flow template meets the following requirements: The difference between the largest remaining bandwidth ratio and smallest remaining bandwidth ratio of physical output interfaces becomes larger than or equal to the periodic adjustment upper threshold. The link adjustment might be last for several adjustment intervals. RIR stops link adjustment if one of the following requirements is met:

· The difference between the largest remaining bandwidth ratio and the smallest remaining bandwidth ratio of the physical output interfaces becomes smaller than the periodic adjustment lower threshold.

· The adjustment interval is the 20th interval after link reselection is triggered.

Usage guidelines

Based on link bandwidth, RIR supports the following link load balancing modes:

· Per-packet mode—Flow-specific link load balancing mode that takes effect only on traffic that matches the flow template where this mode is enabled. This mode can distribute the same session to different links for transmission.

The mechanisms of the per-session periodic link adjustment mode are as follows:

a. RIR selects the physical output interface with the lowest bandwidth usage for a session. The used bandwidth is the actually used bandwidth plus the per-session expected bandwidth.

b. RIR selects a link among the links available for the selected physical output interface by comparing the bandwidth usage of the links. The link with the lowest bandwidth usage is selected as the optimal link. The used bandwidth is the actually used bandwidth plus the per-session expected bandwidth.

· For bandwidth tolerant link selection—If multiple links meet the requirements of a flow template, RIR selects one optimal link for each session of the flow template from these links. The link selected the last time for a session takes precedence over the other links for that session. If RIR performs link selection for a session for the first time, it uses the following process:

c. Selects a physical output interface based on the remaining bandwidth weights of the available physical output interfaces.

d. Selects a link among the links available for the selected physical output interface based on the remaining bandwidth weights of the links.

The per-session expected bandwidth is added to the used bandwidth.

In per-session periodic link adjustment mode, the device periodically detects the bandwidth usage of physical output interfaces for all links that have RIR sessions at the configured adjustment intervals. RIR reselect links for sessions that match a flow template if the pyhsical output interfaces for the links in the flow template meets the following requirements: The difference between the largest remaining bandwidth ratio and smallest remaining bandwidth ratio of the physical output interfaces becomes larger than or equal to the periodic adjustment upper threshold. The link adjustment might be last for several adjustment intervals. RIR stops link adjustment if one of the following requirements is met:

· The adjustment interval is the 20th interval after link reselection is triggered.

For a flow template, the per-packet load balancing mode takes precedence over the global per-session periodic link adjustment mode. If the per-packet load balancing mode is not enabled for a flow template, the flow template uses the global link load balancing mode.

Parameters

nqa-id: Specifies an NQA link quality operation by its ID, in the range of 0 to 128.

Usage guidelines

An NQA link quality operation allows a flow template to start UDP jitter probes based on the probe parameters in the operation in order to detect the quality of links.

You can configure a quality policy for a flow template to associate the flow template with an SLA and an NQA link quality operation. The device monitors the quality of links in the flow template based on the NQA link quality operation and compares the NQA probe results with the thresholds in the SLA. If all parameter values in the probe results of a link are lower than or equal to the thresholds in the SLA, the link is qualified for the flow.

To differentiate service flows that have different link quality requirements, associate the flow templates with NQA link quality operations that contain different probe parameter values. Two NQA link quality operations with different probe parameter values might offer different probe results for the same link.

In a VXLAN network, the NQA link quality probe targets are VXLAN tunnel interfaces enabled with the RIR client.

The device supports a maximum of 129 NQA link quality operations.

Parameters

4g: Specifies the 4G type.

internet: Specifies the Internet type.

mpls: Specifies the MPLS type.

mstp: Specifies the MSTP type.

index link-index: Specifies a link index in the range of 1 to 65535.

preference preference: Specifies a link preference in the range of 1 to 255. The lower the value, the higher the priority.

Usage guidelines

RIR preferentially selects links with higher preference.

The link type and link index specified in this command identify links on a VSI interface. .Because a VSI interface can have only one VXLAN tunnel between a hub and spoke, this command sets the link preference for a specific VXLAN tunnel.

You can assign the same link preference value to different links in the same flow template.

Examples

# In flow template 1, set the preference of MPLS link 1 to 100.

Parameters

source: Specifies the peer device as the source device for application quality probing.

destination: Specifies the peer device as the destination device for application quality probing.

site-id site-id: Specifies the site ID configured during SDWAN tunnel establishment for the peer device, in the range of 1 to 65535.

device-id device-id: Specifies the device ID configured during SDWAN tunnel establishment for the peer device, in the range of 1 to 255.

Usage guidelines

Use this command to specify a pair of peer devices as the source and destination devices for application quality probing. After you execute the probe flow command, the device uses iNQA to periodically probe the application flows with the specified packet signatures for application quality calculation. The application quality probe result is used for application analysis and does not affect link selection.

To modify the peer device settings of an instance, first execute the undo probe flow command to disable application quality probing for all service flows of the instance.

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

Predefined user roles

network-admin

Parameters

interval interval: Sets the NQA link connectivity probe interval in milliseconds. The value range for the interval argument is 0 to 604800000. The value of 0 represents that only one probe is performed.

timeout timeout: Sets the timeout time for waiting for a response to a link connectivity probe packet. The value range for the timeout argument is 10 to 3600000 milliseconds.

Usage guidelines

The device starts to detect the connectivity of all links in flow templates after RIR-VXLAN is enabled. Spokes (RIR clients) performs consecutive probes at the configured intervals and wait for responses for the probe packets. If an RIR client has not received any responses on a link when the probe packet timeout timer expires, the client determines that the link has connectivity issues.

Setting a shorter probe interval obtains more precise probe results but requires more system resources.

Set a shorter probe packet timeout time if the requirement for link quality is high.

In a VXLAN network, the probe targets are VXLAN tunnel interfaces enabled with the RIR client.

Examples

# For RIR-VXLAN, set the NQA link connectivity probe interval to 30 milliseconds, and set the timeout time to 20 milliseconds for waiting for a response to a link connectivity probe packet.

Parameters

flow-id: Specifies a flow template by its flow ID in the range of 1 to 65535. If you do not specify a flow ID, the undo probe flow command disables application quality probing for all flow templates.

Usage guidelines

For specific service flows forwarded through the SDWAN tunnel, use this command to probe the quality of the application flows with the specified packet signature (such as source or destination IP address). The application quality probe result is used for application analysis. You can enable application quality probing for multiple flow templates of an instance.

Before configuring this command, make sure you have configured the following settings:

· Create the associated flow template. Without the configuration, application quality probing cannot take effect on the service flow.

· Use the peer command to specify the role, site ID, and device ID for the peer device.

· Use the signature command to specify the packet signature for application quality probing.

For a specific service flow, the device does not probe the quality of an application flow without any packets matching the specified signature.

You cannot enable application quality probing for the same service flow in multiple application quality probe instances.

nqa nqa-id: Specifies an NQA link quality operation by its ID in the range of 0 to 128. The specified NQA link quality operation must exist.

Usage guidelines

Use this command to specify a link quality for a flow template.

· For RIR-VXLAN, you need to specify an SLA and an NQA link quality operation for the flow template.

· For RIR-SDWAN, you need to specify an SLA for the flow template.

For flow priority-based traffic scheduling, the priority of a flow that matches a flow template is determined by the SLA ID specified in the quality policy of that flow template. The greater the SLA ID, the higher the flow priority. If no quality policy is configured for a flow template, flows that match the flow template have the lowest priority.

You can specify only one SLA and one NQA link quality operation for the quality policy of a flow template. However, you can specify the same SLA or NQA link quality operation for the quality policies of multiple flow templates.

If you execute this command multiple times for a flow template, the most recent configuration takes effect.

Usage guidelines

RIR can be deployed based on VXLAN tunnels or SDWAN tunnels, which are called RIR-VXLAN and RIR-SDWAN, respectively

· For RIR-VXLAN, use the rir command to enable the RIR-VXLAN service.

· For RIR-SDWAN, use the rir sdwan command to enable the RIR-SDWAN service.

When you enable the RIR-VXLAN or RIR-SDWAN service, the system enables the RIR process. When you disable the RIR-VXLAN or RIR-SDWAN service, the system disables the RIR process.

You cannot enable both the RIR-VXLAN and RIR-SDWAN services.

· To enable the RIR-SDWAN service when the RIR-VXLAN service is enabled, you must first execute the undo rir command to disable the RIR-VXLAN service.

· To enable the RIR-VXLAN service when the RIR-SDWAN service is enabled, you must first execute the undo rir sdwan command to disable the RIR-SDWAN service.

Parameters

group-id: Specifies an RIR collaboration link group by its group ID in the range of 1 to 65535.

Usage guidelines

In an RIR collaboration device group, make sure all links to the same device or RIR collaboration device group are assigned to the same RIR collaboration link group. A device in an RIR collaboration device group can select links for service packets from the following links:

· ECMP links configured in the matching flow template on the local device.

· Links configured in the same flow template on devices that belong to the same RIR collaboration device group as the local device. In addition, the links belong to the same RIR collaboration link group as the candidate links on the local device.

You can use this command when RIR is enabled or disabled. However, this command takes effect only when RIR is enabled.

To ensure correct link selection, use this command on each device that belongs to the same RIR collaboration device group. Make sure all links to the same device or RIR collaboration device group are assigned to the same RIR collaboration link group.

In an RIR collaboration device group, make sure the links to different devices or RIR collaboration device groups are assigned to different RIR collaboration link groups.

In different RIR collaboration device groups, the links to the same device or RIR collaboration device group can be assigned to the same RIR collaboration link group. As a best practice to identify links, assign the links to different RIR collaboration link groups.

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

Parameters

4g: Specifies the 4G type.

internet: Specifies the Internet type.

mpls: Specifies the MPLS type.

mstp: Specifies the MSTP type.

index link-index: Specifies a link index in the range of 1 to 65535.

Usage guidelines

This command enables the RIR process if the RIR process has not been enabled. The undo form of this command does not disable the RIR process.

The link type and link index together uniquely identify a link between a hub and a spoke. For a flow template to use a link, you must assign a link type and index to the link. Use this command to configure the link type as 4G, Internet, MPLS, or MSTP. The link type only marks the network type of the link and it does not affect packet encapsulation.

VXLAN-based RIR allows a hub and a spoke to have only one VXLAN tunnel for a VSI interface (a VXLAN). By assigning a link type and index to the VSI interface, RIR can identify the VXLAN tunnel between the hub and spoke.

A VSI interface on a hub (or spoke) can have a VXLAN tunnel to each spoke (or hub). The VXLAN tunnels of the same VSI interface are assigned the same link type and link index.

A VSI interface can be associated only with one link type.

You must assign different link indexes to the same type of links on different VSI interfaces.

Examples

# Set the link type to MPLS and link index to 1 on VSI-interface 1.

Usage guidelines

To avoid NQA probes from occupying too many resources on a hub in a hub-spoke network, configure the hub as an RIR server and configure the spokes as RIR clients.

You can enable the RIR client or server globally or on an interface.

· Enabling the RIR client or server globally also enables the RIR client or server for all interfaces on the device. The interfaces can send or receive link quality probe results.

· Enabling the RIR client or server on an interface allows only that interface to send or receive link quality probe results.

Enable the RIR server or RIR client, or use them in combination, depending on the role of the device in the network.

· If the device acts only as a hub, you can enable the RIR server globally.

· If the device acts only as a spoke, you can enable the RIR client globally.

· If the device acts as both a hub and a spoke, you can enable the RIR server and RIR client on the corresponding interfaces.

When you enable the RIR client or server, follow these restrictions and guidelines:

· In a VXLAN network, only tunnel interfaces support enabling the RIR client or server. The RIR server uses the tunnel interfaces to receive link quality probe results synchronized from RIR clients.

· The RIR client and RIR server cannot be both enabled on the same interface.

· If the enabled role (RIR server or client) on an interface is different from the globally enabled role, the interface-specific role takes effect on that interface.

To modify the role of an interface, you must first use the undo rir role command to remove the original role.

· If the enabled role (RIR server or client) on an interface is different from the globally enabled role, the interface-specific role takes effect on that interface.

Examples

# Enable the RIR server globally.

signature

Use signature to configure the packet signature for application quality probing.

Use undo signature to delete the packet signature for application quality probing.

Syntax

signature source-ip { any | src-ip-address [ src-mask-length ] } destination-ip { any | dest-ip-address [ dest-mask-length ] }

undo signature

Default

No packet signature is configured for application quality probing.

Parameters

source-ip { any | src-ip-address [ src-mask-length ] }: Specifies a source IPv4 address for packets. The any keyword represents any source IPv4 address. The src-ip-address argument represents the source IPv4 address of packets, in dotted decimal notation. The src-mask-length argument represents the length of the subnet mask, in the range of 1 to 32. If you do not specify the src-mask-length argument, the command matches the exact source IPv4 address of packets.

destination-ip { any | dest-ip-address [ dest-mask-length ] }: Specifies a destination IPv4 address for packets. The any keyword represents any destination IPv4 address. The dest-ip-address argument represents the destination IPv4 address of packets, in dotted decimal notation. The dest-mask-length argument represents the length of the subnet mask, in the range of 1 to 32. If you do not specify the dest-mask-length argument, the command matches the exact destination IPv4 address of packets.

Usage guidelines

After you execute the probe flow command for specific service flows, the device will probe the quality of the application flows with the specified packet signatures (such as source or destination IP address).

To modify the packet signature settings of an instance, first execute the undo probe flow command to disable application quality probing for all service flows of the instance.

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

Examples

# Configure the packet signature for application quality probing by specifying the source and destination IPv4 addresses for packets as 10.1.1.1 and 20.1.1.1, respectively.

Parameters

sla-id: Specifies an SLA ID in the range of 0 to 128.

Usage guidelines

To meet the differentiated requirements of services on link quality, configure a Service Level Agreement (SLA) for each service. An SLA contains a set of parameters to evaluate link quality, including the link delay, jitter, and packet loss thresholds.

The device supports a maximum of 129 SLAs.

Examples

# For RIR-VXLAN, create SLA 1 and enter RIR-VXLAN SLA view.

<Sysname> system-view

[Sysname] rir

[Sysname-rir] sla 1

[Sysname-rir-sla-1]

# For RIR-SDWAN, create SLA 1 and enter RIR-SDWAN SLA view.
