Happy Unraid newbie here. But having some issues with NIC sometimes not working. It is working now, but I would appreciate it, if someone would be kind enough to educate me on how this is possible.

 

7.0.0-beta.2

 

My B550 motherboard has a Realtek 2.5 Gb port.

I added a cheapo OEM PCIe card based on Intel x540 with two 10G ports that I would like to leverage for 10G to my network switch's 10G SFP+ port, it's all hooked up and working at the moment (but is not always the case). Just a single connection, no need or plan to use the other 2 vacant ports.

 

So I have mapped as follows:

eth0 - Intel 10G port A

eth1 - onboard Realtek 2.5G

eth2 - Intel 10G port B (2nd port of same board as eth0)

Mapped as such just to simplify it so that the default (first 10G port) is number 0, that's all.

 

In Settings, Network, I have specified static IP addresses on the local network (in part to troubleshoot), so I made them unique such that eth0 (10G port A) is 192.168.0.198, eth1 is 192.168.0.199, and eth2 is unspecified/None. I am trying to get stable operation on the eth0 10G port, but since it has not been always stable, I also have eth1 defined in case I need to fall back and change config or troubleshoot.

 

So right now, after a couple of modifications/tries/reboots, it is working, and Dashboard Interface section shows eth0 as 10000 Mbps and the other two as interface down. This is what I wanted. But what doesn't make sense is that when I ping the host name of the machine (from another client, Windows PC), it returns 192.168.0.199 even though that should be the disconnected eth1 port. I expected to see .198 IP after modifying the config as such. What am I missing?

 

eth0:

IPv4 address:

192.168.0.198

IPv4 default gateway:

192.168.0.1

IPv4 DNS server:

192.168.0.1

 

eth1:

IPv4 address:

192.168.0.199

IPv4 default gateway:

192.168.0.1

(no option of DNS server for some reason, maybe because it is not the default or because it is unplugged?)

 

Bonding/bridging are "No" across the board.

 

ethtool confirms the correct devices (eth0 supports 10000baseT, eth1 only 2500baseT)

It could be that, because eth0 and eth1 was config in same subnet. But this won't the reason cause 10G NIC unstable.

I like binding my unused nic ports to vfio.  Not only makes them available for vm tinkering but also gets them (and their potential conflicts) out of my way in network settings.
