Hello AravindSubbiah,


By the way, before we do that. Let me check the host system. Can you also provide the following details.


  1. Are you using onboard i210 network card?
  2. What is the brand and model of your board or system?
  3. Can you provide the link of your latest driver?
  4. What is the exact version of your Linux Ubuntu OS?


If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.


Thank you.


Best regards,

Hi Michael,

1. No, we are not using an on board card.

2. This is the device we are using: I210

3. Driver info:
driver: igb
version: 5.4.0-k
firmware-version: 3.25, 0x800006eb
expansion-rom-version:
bus-info: 0000:06:00.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: yes

4. Linux: Ubuntu 16.04.7 LTS

Since we were able to access Linux system time, we tried phc2sys which is supposed to synchronize Linux system time according to HW clock on network card. We are not able to get the system clock to get synchronized.

Let us know if any other info is required.

Thanks,

Aravind Subbiah
