Description

 

This article describes how to add an SLA target to an existing Health Check. Use this SLA target on another SD-WAN rule.

 

Scope

 

FortiGate v7.0, v7.2, v7.4, v7.6.

 

Solution

CLI Configuration:

 

config system sdwan
    set status enable
        config zone
            edit "sdwan-dc100"
            next
end


config members
    edit 101
        set interface "advpn101"
        set zone "sdwan-dc100"
        set source 10.136.32.16
    next
    edit 102
        set interface "advpn102"
        set zone "sdwan-dc100"
        set source 10.136.32.16
    next
    edit 104
        set interface "advpn104"
        set zone "sdwan-dc100"
    next
end


config health-check
    edit "SLA_DC100"
        set server "10.136.64.1"
        set embed-measured-health enable
        set members 101 102
            config sla
                edit 1
                    set latency-threshold 55
                    set jitter-threshold 20
                    set packetloss-threshold 1
                next
            end
    next
end


config service
    edit 2
        set name "SLA2"
        set mode sla
        set dst "192.168.2.22"
        set src "192.168.1.11"
            config sla
                edit "SLA_DC100"
                    set id 1
                next
            end
        set priority-zone "sdwan-dc100"
    next
    edit 1
        set name "Original"
        set mode sla
        set dst "Corporate_subnets"
        set src "Corporate_subnets"
            config sla
                edit "SLA_DC100"
                    set id 1
                next
            end
        set priority-zone "sdwan-dc100"
    next

    end
end

 

  1. Add SLA target on Health check SLA_DC100 via CLI:

 

FGT-SDW-1 (health-check) # edit SLA_DC100
FGT-SDW-1 (SLA_DC100) # config sla
FGT-SDW-1 (sla) # edit 2
new entry '2' added
FGT-SDW-1 (2) # set latency-threshold 100
FGT-SDW-1 (2) # set jitter-threshold 30
FGT-SDW-1 (2) # set packetloss-threshold 5
FGT-SDW-1 (2) # end
FGT-SDW-1 (SLA_DC100) # end
FGT-SDW-1 (sdwan) # end

 

  1. The GUI will show the 2nd SLA Target:

  1. It is now possible to use it on another SD-WAN Policy.
