Minimum number of links for a rule to take effect

In sla and load-balance modes, you can specify the number of links that must be up for the rule to take effect.

Example

In this example, ports 1 to 4 each have 10Mbps of bandwidth, and port 5 has 50Mbps. An application requires 35Mbps of bandwidth, so the SD-WAN rule balances the traffic between ports 1 to 4. If one of the links goes down, all of the traffic must be passed to port 5, so the minimum required number of links is 4.

To set the minimum number of links in a rule:

config system sdwan
    config service
        edit 1
            set mode load-balance
            set minimum-sla-meet-members 4
            set dst <destination>
            config sla
                edit <sla>
                    set id <id>
                next
            end
            set priority-members 1 2 3 4
        next
    end
end
