Performance SLA for WAN links

Hello Benson,

> I am finding advice/recommendation of performance SLA setup for one Link without sdwan ( virtual-wan-link ), thx?

Looking at your requirement. You can use link-monitor feature (CLI only) on the FortiGate.

This will not work completely as the performance SLA, but it will show you the information on how the link is performing using the command "diagnose sys link-monitor status"

[size="2"]diagnose sys link-monitor status Link Monitor: 0, Status: alive, Server num(1), Flags=0x1 init, Create time: Fri Feb 12 01:52:09 2021 Source interface: port1 (3) Source IP: 10.10.0.21 Interval: 500 ms  Peer: 8.8.8.8(8.8.8.8)         Source IP(10.5.21.50)         Route: 10.5.21.50 ->8.8.8.8/32, gwy(10.5.31.254)         protocol: ping, state: alive                 Latency(Min/Max/Avg): 5.334/5.543/5.450 ms [size="2"]                Jitter(Min/Max/Avg): 0.002/0.122/0.050                 Packet lost: 0.000%[/size][/size][size="2"]                 Number of out-of-sequence packets: 0                 Fail Times(0/5)                 Packet sent: 104, received: 104, Sequence(sent/rcvd/exp): 105/105/106[/size]

Here, you can see the Latency, Jitter and Packet loss on the link.
