Creating SLA Profiles

 

You can use the Create SLA Profile page to create a new service-level agreement (SLA) profile for the current tenant and configure target metrics for the SLA profile.

To add an SLA Profile to the tenant:

  1. Click the add icon (+) on the Configuration > Application SLA Profiles page in the Customer Portal.

    The Create SLA Profile page appears.

  2. Enter the general SLA profile information according to the guidelines provided in Table 1.
  3. Click OK to create the SLA profile. The Application SLA Profile page appears with the new SLA profile information.

    Alternatively, if you want to discard your updates, click Cancel instead.

Table 1: Fields on the Create SLA Profile page

Field

Guidelines

General

Name

Enter a name for the SLA profile.

Name can be a unique string of not more than 15 characters that contains alphanumeric characters and hyphen (-).

Traffic Type Profile

Choose a traffic type profile to apply the class-of-service configuration and priority to the SLA profile. You can select a traffic type profile only when it is in the Enabled state.

SLA Configuration

Choose one of the following options:

  • Use Recommended— To use the default SLA threshold and SLA parameters for the traffic type profile.

  • Enter Custom— To specify the customized values for SLA configuration and SLA parameters for the traffic type profiles.

SLA Threshold

Choose one of the following options:

  • Liberal—To use a relaxed SLA threshold.

  • Baseline—To use the default SLA threshold

  • Conservative—To use a strict SLA threshold.

SLA Parameters

Packet Loss

Enter the target packet loss (in %) for the SLA profile. Packet loss is the percentage of data packets dropped by the network to manage congestion.

RTT

Jitter

Enter the target jitter (in ms) for the SLA profile. Jitter is the difference between the maximum and minimum round-trip times of a packet of data.

Path Selection Criteria

Path Preference

Select the preferred WAN link type to associate with the SLA profile. The options are Any, MPLS, and Internet. Any is the default value. You must select a path preference or configure at least one SLA parameter.

Path Failover Criteria

Enable failover to switch links when the active links fail to meet the SLA criteria. In such cases, the traffic is routed to links that meet SLA criteria. Failover is supported only for MPLS or Internet links.

Note: The Failover option is supported only for bandwidth-optimized SD-WAN networks.

Choose one of the following options:

  • Does not meet one or more SLA parameters—This triggers the path failover if any of the SLA parameters is violated.

  • Does not meet all SLA parameters—This triggers the path failover only when all the SLA parameters are violated.

Advanced Configuration-Rate Limiting

Maximum Upstream Rate

Enter the maximum upstream rate (in Kbps) for all applications associated with the SLA profile. The rate is in the range 64 through 10,485,760 Kbps.

Maximum Upstream Burst Size

Enter the maximum burst size (in bytes). The burst size is in the range 1 through 1,342,177,280 bytes.

Maximum Downstream Rate

Enter the maximum downstream rate (in Kbps) for all applications associated with the SLA profile. The rate is in the range 64 through 10,485,760 Kbps.

Maximum Downstream Burst Size

Enter the maximum burst size (in bytes). The burst size is in the range 1 through 1,342,177,280 bytes.

Loss Priority

Select a loss priority based on which packets can be dropped or retained when network congestion occurs. The chances of a packet getting dropped is the highest when the loss priority is set to High. Other available values are Medium High, Medium Low, and Low.

Real Time Optimized Mode Setting-SLA Sampling

Session-sampling %

Enter the matching percentage of sessions for which you want to run the passive probes.

SLA-violation-count

Enter the number of SLA violations after which you want CSO to switch paths. The range is 1 through 32.

Sampling-period

Enter the sampling period, in milliseconds, for which the SLA violations are counted. The range is 2000 through 60000.

Switch-cool-off-period

Enter the waiting period, in milliseconds, only after which you want the link switch to happen if an active link comes back online. This parameter helps prevent frequent switching of traffic between active and backup links. The range is 5 through 300.

Note

You can also create SLA profiles from the Configuration > SD-WAN > SD-WAN Policies page in the Customer Portal.
