Adding SLA-Based Steering Profiles
You can use the Add SLA Profile page to add a new service-level agreement (SLA)-based steering profile, specify the traffic type profile, SLA configuration, SLA threshold, SLA parameters, path selection criteria, and rate limiting parameters for the profile. Table 1 lists the SLA-based steering profiles that are tuned for specific application categories and traffic types.

To add an SLA-based steering profile to the tenant:
- Select Configuration > SD-WAN > SLA-Based Steering
Profiles.
The SLA-Based Steering Profiles page appears.
- Click the add icon (+).
The Add SLA Profile page appears.
- Enter the SLA profile information according to the guidelines
provided in Table 2.
Note Fields marked with an asterisk (*) are mandatory.
- Click OK to add the SLA profile.
The SLA-Based Steering Profiles page appears with the new SLA profile information. You are returned to the SLA-Based Steering Profiles page and a confirmation message indicating that the SLA-based steering profile was added is displayed. The page refreshes to display the SLA-based steering profile that you added.
Alternatively, if you want to discard your updates, click Cancel instead.
Note After you add an SLA-based steering profile, you must add an SD-WAN policy intent that references the SLA-based steering profile in order to enable site-to-site traffic.
Table 2: Fields on the Add SLA Profile page
Field | Guidelines |
|---|---|
General | |
Name | Enter a unique string that can contain alphanumeric characters and hyphens (-); the maximum length is 15 characters. |
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:
|
SLA Threshold | Choose one of the following options:
|
SLA Parameters | |
Packet Loss | Enter the target packet loss (in %) for the SLA-based steering profile. Packet loss is the percentage of data packets dropped by the network to manage congestion. |
RTT | Enter the target round-trip time (RTT) for the SLA-based steering profile. |
Jitter | Enter the target jitter (in ms) for the SLA-based steering 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. Select the preferred path (MPLS, Internet, or Any) to be used for site-to-site traffic. If a WAN link type that matches the preferred path is enabled for site-to-site traffic, then that WAN link type is used for site-to-site traffic. If you specify that any path can be used, then there is no preference and all site-to-site-traffic-enabled links are used in a load-balancing mode. |
Path Failover Criteria | Specify the failover criteria to determine how links are switched 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: Path failover is supported only for bandwidth-optimized SD-WAN networks. Choose one of the following options:
|
Advanced Configuration- | |
| Rate Limiting | |
Maximum Upstream Rate | Enter the maximum upstream rate (in Kbps) for all applications associated with the SLA profile. Range: 64 through 10,485,760 Kbps |
Maximum Upstream Burst Size | Enter the maximum upstream burst size (in bytes). 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. Range: 64 through 10,485,760 Kbps |
Maximum Downstream Burst Size | Enter the maximum downstream burst size (in bytes). Range: 1 through 1,342,177,280 |
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 Note: The following fields are applicable only for sites configured with the real-time-optimized SD-WAN mode. | |
| 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 seconds, for which the SLA violations are counted. The range is 2 through 60. |
Switch-cool-off-period | Enter the waiting period, in seconds, 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. |
