If i have 2 SLA performance to monitoring packet loss and latency to google and microsoft and both SLA used in single sdwan rule.

Then the when sdwan will switch to the next member?

if only one sla is not met, example high packet loss to the google but rest of 3 sla targets is good will the traffic switched?
Or sdwan will switch if all 4 targets is not met?

If any one SLA target fails (for example, high packet loss to Google),

Even if other SLAs (e.g., Microsoft) are fine,

The member is marked as “SLA failed” for that rule.

Yes, the SD-WAN will switch traffic to the next best member if any one of the SLA performance checks fails for that member.

Thanks.

But now if i have 2 sla target with only monitor the latency to google and microsoft, can sdwan switch only if both latency is high and ignore if high latency occurs only for google or microsoft?
