I require to capture the traffic on wireshark.More or less the way if using SPAN port on Cisco switch.
So found if sflow can be used on Fortigate as I do not have any managed switch in our network.
Configured and sflow collector ip as the wireshark PC and enabled interface on fortigate internal interface.
I can see still not traffic does it captures except the one destined to or from the wireshark pc.
Any expert suggestions please.
