Massive packet loss/NIC issues with new Dell 7070 Ultra in FOG
The Dell 7070 Ultra is a desktop
Ok its similar to the 3060s we use then, just the 7000 series. (off topic, but dell has kind of made a mess with series numbers now its hard to tell what is what).
So do you have a Dell usb c dongle from a 7400 or 3530 you could test with? It needs to be a Dell usb C dongle (ethernet adapter) so its supported by the firmware for pxe booting. I guess you could use a WD15 or WD19 dock. The idea is to try to use another network adapter than the built in one.
I can tell you the Intel I219 network adapter has been supported since the 4.12.x linux kernel.
Something else to try is to boot a linux live OS and see if you still have networking issues. FOS Linux runs on a current linux kernel so if its supported by linux then FOS Linux should be able to communicate with it.
@no0NE Have you had the first device (working fine) on the same switch port and with the same cable that you now see the problem with the second “faulty” device?
Absolutely sure the firmware is the exact same version on both?
Thanks for the reply!
As you say, the issue is not on the server side, but rather on the client.
The Dell 7070 Ultra is a desktop built with laptop components (google it, it’s quite cool ). It’s powered through USB-C from our monitors (65w), together with DP & USB hub functionality, but the ethernet is connected separetly directly to the ethernet jack of the PC (Intel I219-LM network card).
I ping and scan the traffic going to the PC from my admin PC, the FOG server, the other PC of the same model, can start the ping in windows and all’s fine, but as soon as it boots into FOG the packet losses starts to occur.
To isolate as much problem sources as possible, i’ve also connected ethernet directly between FOG server and this PC and the packet losses is still the same - massive!
I’ve also tried with dumb & smart/L3 switches and results are the same…
Thanks for trying to help brainstorm how to find the error source since i might’ve missed something, but from these points i think i’ve eliminated your possible fault points.
@no0NE My personal idea is that its a target system firmware issue.
Since you are talking about a 7070, is that a portable or a desktop?
I really don’t think its the FOG server at this point, but instead something on the endpoint side.
If this device is a portable are you using a usb c to ethernet dongle?
Where are you seeing the packet loss?
If you have these devices connected to an enterprise managed switch, are you seeing errors on the port counters?
If this is a managed enterprise switch see if the green ethernet (802.3az) is enabled on the switch port. If it is disable it to see if it resolves the issue.
Just to add; most of the times trying to start the imaging process on “PC #2” it will fail after trying to check in for a while with an error stating “no route to host” or similar connection related errors (due to all the packet losses…) with an automated reboot after 1 min. sometimes though it slowly gets to the PartClone stage and then is stuck there at ~0.5-1mB/s with continued massive packet loss.
I’d like to try it out on further PC’s of this model, it feels like a NIC/Hardware issue if it’s only this PC, but the first PC works repeatedly every time (20+ times). And it works without issues in Windows/UEFI…
The packet loss against this PC is the same when pinged from any PC on the network, incl. from the FOG server itself.
Latest available UEFI/BIOS for this model (v 1.0.2)
