The healthcheck sla command references health check or link quality indicator objects in a global routing policy or multi-ISP policy-based route.
The undo healthcheck command cancels the reference of the health check or link quality indicator objects.
| Parameter | Description | Value |
|---|---|---|
healthcheck-name |
Specifies the name of a health check object. |
The health check object must already exist. |
sla-name |
Specifies a link quality indicator. |
The link quality indicator must already exist. |
Versions earlier than V600R007C20SPC300, All models except USG6635E/6655E, USG6680E and USG6712E/6716E support this command.
In V600R007C20SPC300 and later versions, all models support this command.
The health check or link quality indicator objects are not referenced in a global routing policy or multi-ISP policy-based route.
A health check object is created using the healthcheck name command. A link quality indicator is created using the sla name command.
Link quality detection depends on the health check. If more intelligent route selection is required based on the link delay, jitter, and packet loss rate, you need to reference a health check object and link quality indicator in the route selection policy. Referencing the health check on a route selection member interface can detect only the connectivity of the interface link.
After health check and link quality indicator objects are referenced in a global routing policy or multi-ISP policy-based route, the FW checks whether the link quality (delay, jitter, and packet loss rate) meets the quality requirements of link quality indicators in real time. The links that do not meet the requirements are not allowed to participate in intelligent uplink selection until their link quality meets the requirements.
