Hello,

I'm trying to troubleshoot an issue with a lot of network drops.

Things I've tried;

Updated bios/bmc to current ( Supermicro X11ssh-ctf)

Updated to Unraid 7.2.4

Replaced network cable

replaced switch.

ran wireshark, no glaring errors.

I've isolated the device to just a switch and a cable and it's still erroring.

Not sure what to do with this? Faulty on board NIC?

Logs are attached.

Does it help if you enable bridging for eth0?

It helps a bit, it slowed it right down, but it's still dropping.

Out of curiosity, what router are you using?

Cause its been happening for a while, but so far only a few people have been affected and theyre, im pretty sure, all german.

Since my last comment there, it has been changed to validated, so i have high hopes that soon™ you could disable bridging and macvtap and you should no longer experience the drops.

The macvtap drops are really bad, but if you host anything, with briding enabled, the drops are so far and few between, it shouldnt impact anything you host, at least from what ive been seing since then.

The usual switch was a tp-link 10g. I don't recall the model. I swapped it out for a dlink 1g for a test and the same thing was observed. I disabled bridging, but can't find the option to disable macvtap. Docker and VMs are turned off.

A few drops can be normal with some NICs, as long as you don't see ill effects, but recommend leaving bridging enabled if it's better like that.
