Good day all.
I’ve got a bit of a pickle here. I replaced a NIC that failed. The original NIC was a 2 port 10GbE NIC, and the replacement is the single port version of the same NIC. I’ve gone through, and setup the network interface the same as it was before. It was using a VLAN, so I deleted the VLAN interface, and re-created it with the same settings (IP address, and VLAN tag) and attached it to the new Parent Interface. But it just doesn’t work. In the Dashboard, I can see the interface, it shows connected, but doesn’t populate the IPv4 address or show that the parent has VLANs associated with it.
Any help would be appreciated!
Welcome to the forums!
Please read Joes Rules (in my tag line) and post the hardware specs, and look at the Network data requested, and yes, even the version of TrueNAS you are running. Once you have posted this data I am confident you will get some dialog going on to help you fix the issue.
OS Version:TrueNAS-SCALE-24.04.2.1
Product:B550 UD AC
Model:AMD Ryzen 5 4600G with Radeon Graphics
Memory:31 GiB
The NIC is Intel 82599 10 Gigabit Adapter
The unit was running perfectly for over a year, then the NIC died. 
Joes rules are a bit TL;DR though 
Have you tried the dead NIC in a different computer? Just in case it’s not the NIC…
Yes. I put it over into one of my LAB ESXi hosts to test. Nic is most definitely dead.
I just nuked the box. Re-built it, configured, and imported my storage. Everything is back up and running. It was a weird one.
Possibly could’ve reset the networking in the console
If it happens again in the future, how would one go about doing that? Would probably be a lot faster than the rebuild process.
