[bart sikkes <b.sikkes@xxxxxxxxx>]

hello,

but do you see other traffic then the mentioned broadcast traffic?
what about when you test with ping, telnet, ftp, .....

i would focus on checking if you have the port monitoring setup
correctly (perhaps try with other systems / ports), wireshark with
default settings should just work if the traffic is being provided
correctly in my opinion.

greetings,
bart
