Network issue br0


Recommended Posts

Hi -  im new to unraid so pardon me if my question is dumb 🙂

 

I have a dual nic in my unraid system, one 10Gbit and one 1G - setup with the 10Gbit as eth0 and 1gb as eth1. Is this a bad idea, should I just remove the 1gb link completely? Eth1 says "interface down" even though it is cabled and works. 

 

I see these errors in my syslog - and I am worried it will give me problems.  Currenly everything seems to be working, docker/vm file hosting working just fine, but I do not like these errors, and I dont quite undertand them.

 

May 4 09:59:19 Farmen03 kernel: br0: port 2(vnet0) entered blocking state

May 4 09:59:19 Farmen03 kernel: br0: port 2(vnet0) entered disabled state

May 4 09:59:19 Farmen03 kernel: device vnet0 entered promiscuous mode

May 4 09:59:19 Farmen03 kernel: br0: port 2(vnet0) entered blocking state

May 4 09:59:19 Farmen03 kernel: br0: port 2(vnet0) entered forwarding state

 

Anybody 🙂

Did you ever solve this? I'm experiencing the same thing...

//edited: needed NIC offloading off.

 

Hello,

 

This is my first post .... as far as I remember .... but I though this might help others so here it goes.

 

Had issues with VLANs enabled on a 10Gbps adapter and after the first reboot copying files using samba shares on any IP of any VLAN interface, I got the same disabled state kernel errors in the logs.

After a shit-ton of searches and failed diagnostics, I remembered about Flow control and NIC offloading, so I installed the Tips and Tweaks plugin and set Disable NIC Flow Control to Yes, Disable NIC Offload to "Yes" and Rx and Tx buffers to 2048 and it now works perfectly.

Hope this helps you too.
