Open Bench Logic Sniffer / Re: Capture Ethernet Packages
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).
