4200 - LAN port flapping
-
@i298X9wY1jGQ Running at 100M is typically a sign that one wire-pair within the ethernet cable is not connecting. If you already replaced the cable (and are sure the replacement is good), the next most likely theory is a dirty connector pin within the port. Try cleaning the pins. If that doesn't help, it's a faulty port.

Yeah, tried cleaning the pins even though they looked very clean since this is a brand new unit. However, after rebooting the unit, the port stays active but only at 100M. I'm not sure if this is a faulty port or something funky going on with the software.

Do you have the port set to a specific speed? On the 4200 it should pretty much always be set to 'default'.

I tried forcing my laptop to use 1G full-duplex but PORT 2 still auto negotiates at 100M. Then, I tried forcing PORT 2 to negotiate at 1G and it is now showing "no carrier" and is completely off (no activity lights). After making the change to negotiate at a specific speed always makes the port unresponsive and requires a reboot for it to become active again.
I'm on my third cable now and can probably rule out any issues with the cables I'm using.

Looking at the 4200 documentation, there's no section for the RJ-45 LED activity lights so I'm not sure how to interpret the colors. I see other models have documentation going over the activity lights. Examples are here and here.

Yeah, that seems like a documentation oversight. However, "ifconfig" in the shell will tell you the truth about port speeds. On my 4200 I see
media: Ethernet autoselect (2500Base-T <full-duplex>) ... media: Ethernet autoselect (1000baseT <full-duplex>)on my two active ports, and those are both right.

I ended up reinstalling pfSense fresh. Confirmed in the shell that PORT2 was still showing as 100baseTX <full-duplex>. Not really sure what else to do here.

If this is a new unit, it sounds like RMA time. I think you've covered every possibility other than faulty port hardware.

Yeah, the rep I had been working with initiated an RMA. I was really hoping I would not have to do that but it is what it is.
Thanks all for the help!

As a test try just linking two ports together directly and then check the link state at the CLI with
ifconfig -v.There shouldn't be an issue linking at 1G. You may have a bad port.
