ARP Request time out #231

Open awaisather opened 5 years ago

awaisather commented 5 years ago

Hi, I am running epserver and epwget for single-process, multi-threaded usage and every time I am getting arp request time out error. [ ARPTimer: 323] [CPU 0] ARP request for 10.10.1.30 timed out.

I have used following Intel NIC's separately but still error remains same:

I350 Gigabit Network Connection 152 Ethernet Controller X710 for 10GbE SFP+ 1572

Does anyone know about this issue?

Can you please share the following details:

  1. epserver.conf contents,
  2. epwget.conf contents,
  3. IP addresses of the two NICs.

Please make sure that NetworkManager is turned off.

Thanks for your response,our problem is solved, we were trying our setup using router gateway instead of using lan.using lan solved our problems.

I’m getting the same problem and I have turned off the NetworkManager. How did you solve it?

Please check if you can run the test successfully with static ARP table entries correctly first. Please see the format of how you can set ARP entries by looking at config/sample_arp.conf. The file should be copied to apps/example/config/ subdirectory. If, after setting the files (on both sides), you still see the same errors, then something else may be wrong. In that case, please share the contents of the following files: epserver.conf, epwget.conf and the ifconfig dpdk0 output of both machines.
