How do PoE ports connect to the system?

Thanks! I have a couple of follow-up questions, if you don't mind. On this new setup, where I have only ever plugged in one cable to it, I see some links up and I have guesses as to what they are but was hoping for confirmation. I have plugged a cable in to port A (the "wan" port, bottom left corner as viewed looking at the RJ45 ports from the cable's perspective), and the system got an IP address via dhcp as expected. I see 5 ports up across both switch chips. On the realtek chip I see 4 ports up, port 0, port 1, port 6, and port 7: pvid: 1 link: port:0 link:up speed:1000baseT full-duplex txflow rxflow auto pvid: 1 link: port:1 link:up speed:1000baseT full-duplex auto pvid: 1 link: port:6 link:up speed:1000baseT full-duplex txflow rxflow pvid: 1 link: port:7 link:up speed:1000baseT full-duplex txflow rxflow on the ip179h (poe) chip I see port 8 up: Port 8: pvid: 1 link: port:8 link:up speed:1000baseT full-duplex Here are my guesses about how these ports are connected: one of them has to be connected to the CM4, perhaps that is port 0? Also, is this the interface represented by eth0 in the kernel that I see? admin@interceptor:/etc/udev/rules.d$ ip a s eth0 2: eth0: mtu 1500 qdisc mq state UP group default qlen 1000 link/ether e4:5f:01:c5:90:03 brd ff:ff:ff:ff:ff:ff inet6 fe80::e65f:1ff:fec5:9003/64 scope link valid_lft forever preferred_lft forever I would also guess that port 1 is port A (wan), is that correct? This leaves 2 ports left on the rtl chip, does one of them go to the ip179h chip? If so, which one? I would also guess that port 8 on the ip179h chip connects back to either port 6 or port 7 on the rtl chip. Is that right? If so, which is it, port 6 or port 7? Thanks very much for your help! Tom
