i219LM and i211AT LAN adapter

Hi everybody,

Is it possible to keep alive the ethernet connection always even if cable is "disconnected" from the adapter (i219LM and i211AT LAN adapter) ? This is required because in case of power shutdown, when system restarts we need that ETH connection keeps quickly alive before all other devices around (switches, plc etc.) otherwise we loose communication. As systems are far away from our office it would be very hard to restore the working process because no operator is near by.

Thanks a lot

      Hi AlfredoS,

      yes...as you wrote we need more time to assess your recommendations because our customer is busy at the moment so i cannot confirm or not what you told me. For this reason, if you haven't other suggestions i think you can close this ticket now. I'll let you know asap the customer will get me a feedback about the troubleshoot.

      Thanks a lot for your precious help, thanks again...Alex.

      Hi Alfred,

      we tried the setting suggested on i219LM but disconnecting the cable the IP address disappear.

      IPconfig command replies with "Adapter not connected".

      Could you help us ?

      Thanks.

    Hello Alexntk,


    Thank you for your kind patience.


    Please see below update from our engineering level.


    It is not possible for a connection to stay active when it is physically disconnected, that's how Ethernet works. If this is not what you meant by your query, please let us know and we will further investigate.


    Have you considered using static IP address? This will ensure that when you reconnect you always have the same IP address. However, when you disconnect the Ethernet you don't have an IP address.


    Can you check if setting up a Loopback address is an option/applicable for you? We believe this can install a Microsoft Loopback Adapter that emulates an Ethernet card which you can assign a dummy IP address. You can also consider contacting Microsoft to verify this with them.

    https://docs.microsoft.com/en-us/previous-versions/tn-archive/cc708322(v=ws.10)?redirectedfrom=MSDN


    Let us know if you have additional questions and clarifications.


    Looking forward to your reply.


    Should there be no response, I’ll make sure to reach out after 3 business days.

      Hi,

      I was able to test two network cards with Realtek controllers inside. If you set the static IP address, the controller retains the IP address even if the cable is pulled out from the network card. Why doesn't this happen with your network adapters? What has been changed or removed to prevent the same behavior with Intel devices?

      Thanks a lot.

    Hi Alexntk,

    Thank you for waiting for our update.

    While we were checking, these questions came into mind which will help us find an answer for your question regarding the realtek cards:

    1. We would like to know how you confirmed that Realtek cards still provide a Static IP Address even if the cable is disconnected. When you disconnect a cable from these cards, do you retype IPConfig, and they still show with a Static IP Address?

    2. We would also like to ask if you tried the Microsoft Loopback Adapter recommendation by our engineers. It involves installing a Microsoft Loopback Adapter which can emulate which you can assign a dummy IP address.

    We look forward to your reply. Should we not get your reply, we will follow up after three business days.

      Hi AlfredoS,

      I tried two network cards with RTL 8169/8110 PCI and 8168B / 8111B controller from Realtek and I confirm that if set with a static IP address, when the cable is removed the ping command response is still alive. This does not happen if a DHCP address is assigned. For this reason i will propose this work-around to my customer to bypass the problem. Thanks.

      P.S. Microsoft Loopback Adapter fails after customer's test, but maybe customer miss something inside configuration. Have you a short guide about how to configure it correctly ?

      Thanks
