I have installed the 10 GbE network, which setup a direct link with my Ubuntu server. It works perfectly and can transfer up to 1GB/s. But here is a wired issue. 

 

On every Unraid system reboot, I need to unplug the SFP+ adapter and replug it. Otherwise It won't connect to my Ubuntu server. Just unplug the cable and replug isn't work. And this setup worked perfectly with the previous with Synology DSM 6.2.1 system.

 

Current Unraid System version: 6.9.2

 

Here is my Interface Config

 

10G Interface Config:

Enable bonding: No
Enable bridging: Yes
Bridging members of br1: eth1
Network protocol:
IPv4 only
IPv4 address assignment: Static
IPv4 address: 192.168.10.5/24
IPv4 default gateway: 
Desired MTU: 1500
Enable VLANs:

 

Here is pci info

03:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)
03:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

Add more info.

What kind of Switch are you using?

 

I am realizing the same Problem now and then, with different SFP+ modules (RJ45 / Fiber / DA) after a reboot or power on of my windows pc. Somtimes.

It looks like the Port gets jammed within the MikroTik switch. There is no cure unless I pull out the module from the switch and put it back in (doing the same on the PC side does NOT fix it).

 

It happens too rarely to get it pinned down, but, as usal, it always happens when you are not suspicious anymore :-)))

 

But I am quite sure, it has nothing to do with the OS, kind of Card, kind of Module and so on.

Thanks for your advise. I am directly connected 2 10G card. Ubuntu Server <------- cable -------> Unraid NAS, without additional switch. I am suspected on the hardware too. But I never have this issue before I switch to the Unraid system. And it is 100% reproducible issue. So I am get confused on why.

OOh, just "back to back". Then it might be helpfull to you to turn off "flow control" within the lan cards. It MIGHT happen, that one card issues a "please stop!" frame, and then gets turned off. Coming back on may find a still blocked partner and because the rebooted one does not send a "please continue!" frame, it is locked until the cows come home.

Just give it a try, its a useless feature anyway if only two machines are in the net.

I turn off the "flow control" using using this tutorial. And the 10G network is working after 3 reboot and 1 power off. It seems the issue resolved. Thanks a lot for your help.

 

I will give it two more days for testing before tag this issue as resolved.

yeah try it carefully. But it sounds quite good already, so lets hope it has solved the issue

It works like a charm, Thanks @Michael Meiszl.
