I wasn't expecting the Ethernet ports. I would love to be able to plug this in an know in a second what tagged vlans are preset, what addr/mask the DHCP server offered, is PXE an option? blink an LED if there's a new RA, ipv6 neighbor, etc. Blink an LED if there's been a 802.3x pause frame in the last 500ms, or 802.3Qbb while we're at it. With the pair of ports, let me MITM so the 802.1X negotiation can take place before I start sniffing.

More ideas:

let me build an ARP table, then give me a button to send WoL packets to host(s) of my choosing.

Let me generate p0f fingerprints on MITM'd traffic.

you are not getting ARP of hosts that are sleeping in WoL waiting to be ran

Correct. But it's easier for me to power on a device and let it DHCP request than it is to have to type the mac address in on a d-pad keyboard.

Good luck guessing which's which in busy network, or displaying it on tiny screen.

You do know they make proper network troubleshooting tools, right?

I currently do all this with my laptop and wireshark, it just takes time, a USB-C-to-1GBaseT adapter (my ultrabook doesn't have a built-in port) and I have to figure out the capture filter, and all that that still doesn't let me MITM like this dual port device would.

What would you use instead?
