AGX Xavier Dev Kit Ethernet Port - RX Drop

Hello everyone,

We flashed the JetPack-5.0.2 on AGX Xavier Dev. Kit from SDK Manager.
After the Jetson OS flashed and system booted up, we got a problem on the Ethernet interface.
There is a regular package dropping situation on the RX side (2 packets dropping in each second).

If you need more info, please let me know.

Best Regards,
Mehmet

I won’t be able to fix this, but I’ll suggest an initial place to start…

  • Let the network run for a minute or two so errors have occurred.
  • Show a log of:
    ip -s addr
  • Show a copy (after running for a minute or two) of:
    /proc/interrupts
  • The output of:
    hwinfo --network
  • Assuming the interface is eth0, show its description via:
    sudo ethtool eth0
  • Describe physical topology, e.g., if this goes to a managed or unmanaged switch, and then to a router, and if all of the traffic is on an internal network, so on. Anything to describe how it is interconnected.
  • Briefly describe what kind of load the system is under at the time, and the “density” of the network traffic.

Is jp5.1 sill able to reproduce this issue? How to observe this behavior?

Hello @linuxdev and @WayneWWW

Thanks a lot. We flashed the JetPack-5.1 with SDK Manager and got the same problem in it.
Then, we flashed JetPack-4.6.3 to reproduce this issue. However, the ethernet connecting has not any dropped packages.

Here are the results of the commands in JetPack-5.1:

Thanks again

We will check. Thanks for reporting.

Just to reiterate what is already known, those logs verify that:

  • The network is working correctly (no errors or overruns).
  • The receive side of eth0 is receiving packets faster than it can process, and dropping frames.

Still, I’d like to see these on the failed version:

  • Show a copy (after running for a minute or two) of:
    /proc/interrupts
  • The output of:
    hwinfo --network
  • Assuming the interface is eth0, show its description via:
    sudo ethtool eth0

I’ll add that it is a hardware IRQ which services received packets. Certain network settings (not shown with ip -s) also change the timing of what is received. The above would still be useful.

Hi,

It looks like we cannot reproduce your issue on rel-35.2.1. Could you also test with 35.2.1?

Or share how is your environment setup that can reproduce issue?

Hello @linuxdev
Thanks for the clarification.

@WayneWWW
Thanks for the confirmation.

We created an isolated network from our network.
After testing it with iperf3 and keeping it up for a long time (more than 1 hour), we do not get any problems both JetPack-5.0.2 and JetPack-5.1 (rel-35.2.1).
I guess there are something cause this issue from our network.

Sorry for wasting your time.
Thanks a lot

It is never a waste of time. I’ll add that sometimes network MTU/MRU and fragmentation will differ from one network to another. Details like packet size relative to the MTU can greatly change what happens even when the network is otherwise 100% valid. Or, the actual data received could have an effect on the load during fragmentation reassembly. So there are a lot of details to consider from every angle if you want to figure out non-fatal network issues.
