Issue with I340-T4 Intel 82580 Network controller

[abel408]

I have an Intel 82580 Network controller that I've been having issues with.

I just have a very simple network on it.
OPNSense via igb0 82580 port (10.134.0.1) ---> TP-Link Switch (10.134.0.2)


When the OPNSense box starts up, everything works fine. I can connect to the switch and all devices attached to the switch. Then, for no apparent reason, the connection between the switch and OPNSense box breaks. Both devices still see an active connection, but the OPNSense box loses the ARP entries it had for the switch and devices on the switch. They only way to get the connection back is to reboot the OPNSense box. Sometimes it will go hours without losing the ARP entries, sometimes only minutes.

I had a VyOS router in place of the OPNSense box before and never had these issues so I know there is nothing wrong with the switch.

I just upgraded to the latest version and I'm still seeing this issue.

I have attached other devices to the Intel 82580 network controller and they also lose their ARP entry. The onboard network controller works fine.

I'm having the same issue, with a slighty different setup.
I'm using an old cisco blade server with the latest proxmox 5.0.9. This server is connected with a trunk to a cisco switch in 1GB.

And everything is working fine, and suddently, after approx 24 à 48 hours, I'm losing a virtual interface.
LAN-WAN-GUESTS are still working, DMZ not.
Once I restart the virtual interface (disable - enable), the connection is back.

I've now fix all network card to 1000baseT. Fingers crossed that it stays stable now...


My opnsense version is: OPNsense 17.1.6-amd64.

My Promox config, with network card Intel E1000

Let me know if I can help in any way to troubleshoot it a bit more...

[brononius]

No luck, the port just went down again. 
A reboot and eveyrthing is back online. Don't have the time now to go through the log files...

So fixing the speed didn't resolve the issue.

[faunsen]

You have many Ierrs on em1 (vmbr777). Is this the DMZ interface? Can't see a public IP address.
2 discards because of memory problems and 5% of the packets are out of order.
Any errors from dmesg?

Did you check the Proxmox logs?
Do you have bonding on the Proxmox host configured?

vmbr777 is my server DMZ. The public IP/side is on vmbr999, but it's hidden after a router.

No bonding. Just 1 interface in use, with 4 trunks (666 - 777 - 888 - 999). This is the part that bothers me, if it was an issue with the hardware (cisco blade), all vlan's should have issues, not only a virutal vlan, no? Or even on the proxmox side?

I've got the feeling that problem is linked with heavy data transfer on opnsense and my 'virtual drivers'.
Fe when my backupserver starts, a big download... But this is just a feeling.



In att some lines from my syslog-server...

You should check your air con. And the disks. And the switch. Any errors/discards, temperature?
And can you check the errors from a ifconfig on the Proxmox host?

To understand you right. You have one physical interface on the Proxmox blade and put 4 VLANs (btw: What is your understanding of a trunk?) on it and press a backup through this single NIC in and out?
I'd try the virtio nic. 6GByte RAM are good for some performance tweaks. 
FreeBSD uses resources very sparingly with the default settings.

One important thing:
When the problem occurs again, before you reboot the OPNsense VM please do a
netstat -m
netstat -s
sysctl dev.em
etc.
and post it here.

Is the backup traffic going through the DMZ interface?

@abel408
You have more Ierrs than Ipkts!
This could be a hardware problem. Check the cables.
I had recently a series of bad cables that causes this number of errors.
Or maybe the switch has a problem. Any errors on the switch?

[abel408]

This problem isn't isolated to just the switch or cable. Anything I plug into this interface card has this issue. My 2 onboard interface ports are the only ones that are working correctly.

Can you change the interface card too?
Just to be sure 

[abel408]

I was trying to avoid that, but it sounds like that's my only option at this point...

[faunsen]

Yes, the high error rate in contrast to the low traffic let suggest it.
I don't think it's a driver problem.
I use the igb driver too.
Have an eye on hw.igb.buf_ring_size.


Cheers,
Frank

Quite hot. BBQ? You should check your air con. And the disks. And the switch. Any errors/discards, temperature?

No, just an old server running at my house, so not in a cold room or so...

To understand you right. You have one physical interface on the Proxmox blade and put 4 VLANs (btw: What is your understanding of a trunk?) on it and press a backup through this single NIC in and out?.

My understanding of a trunk: multiple VLANs through 1 cable/port...

fe the config on my switch:

Code: [Select]

interface GigabitEthernet0/27
 description Proxmox
 switchport access vlan 777
 switchport trunk encapsulation dot1q
 switchport mode trunk
 switchport nonegotiate
 speed 1000
 duplex full
 spanning-tree portfast
 spanning-tree bpduguard enable

And for proxmox:

For the moment, no more crashes, but I've written it down, so once I see it again, I'll check it.

Is the backup traffic going through the DMZ interface?

For me it does, not sure how proxmox handles traffic, but the backupserver and others are on the same vlan, with the same gateway. But since they're all on the same KVM, I guess it all passes the network interface?


ps @abel408, sorry to post this in your topic. I thought we were having the same issue. If any moderators reads, you can split it if wanted.
