Enable sniffer on FortiSwitch port (in my example port8)
and capture 100 packets –> Alternative: use a mirror port, or check the FortiSwitch documentation, there are several possibilities
config switch interface
edit port8
set packet-sampler enabled
set packet-sample-rate 1 #select the port you’ve enabled the packet-sampler (sp8 = port 8)
diag sniffer packet sp8 ” 4  100 l
Disable sniffer on FortiSwitch port (in my example port8)config switch interface
edit port8
unset packet-sample-rate
set packet-sampler disabled
