That's doubtful.  But since I don't understand Brazilian Portuguese, I can't definitively refute you on it.   Please look up the definition for a hub and a switch and understand the differences.  It's basic to this kind of work and you must have an understanding of the differences between the two to even get started here.

I think that's a hub with switch capabilities.

Port mirroring only applies to a switch. And not all switches (especially the cheaper, unmanaged ones) can handle port mirroring.  All traffic in a hub is available to all ports.  You've got to figure out what you've got.  And that link is in Brazilian Portuguese only--maybe a fellow Brazilian or Portuguese-speaking subscriber to this list might be able to tell us what it says.

I don't know how to configure port mirroring. And maybe it's a hub, and not a switch. This is the one I'm talking about: http://www.braview.com.br/home.asp?pag=Exibir&parent=Switches&chave=107&sb=208&tsb=16+Portas&prod=482

Again, thanks!

Hi Darkk,

You need to enable port mirroring to be able to see all the traffic. By default a switch will only send out unicast/multicast traffic that is appropriate to that specific port you are plugged into.

Hi!

I have 8 computers on a local network, all linked to a Braview HUBSW 16NTX switch, and this switch is linked to a Siemens 4200 modem/router, and this to the ADSL line.

I've been trying to monitor what's happening on the network but I only get results to my own computer, and I needed to monitor the whole network using WireShark.

So, what should I do?
Thanks!
