Open Bench Logic Sniffer / Re: Capture Ethernet Packages
Hello, thank you all very much for your answers and suggestions!
The thing is, I already know how standard sniffing works (HUB+laptop+wireshark) but I'm looking at the possibility of doing the capturing with the fpga and maybe eventually do some internal simple package analysis. My idea is to use an external bord with dual PHYs and connect it to the fpga board. The fpga would contain the MAC and some IP core for ethernet. The packages would enter the fpga be duplicated and saved in memory and then just passed through.
I have never done anything like this and I'm not sure if it even makes sense, but the idea is to have a more portable kind of tap.
Right now I'm just looking at the hardware possibilities and that is why I was asking if this board could be able to handle this and what other hardware I would need attached to it (i.e. more memory, buffers, etc).

Open Bench Logic Sniffer / Capture Ethernet Packages
Hello, Do you think it could be possible to use the Open Bench Logic Sniffer to capture ethernet packages if the input pins were connected to two external daughter boards with the required ethernet PHYs and MAC and then load the correct IP Core to the FPGA? Which do you think would be the extra requirements to be able to do this?
I'm more interested in industrial protocols like real time ProfiNet communication.
Thanks!
