I have 2 systems (win11) and I am using ASUS XG-C100C NIC. Neither NIC will establish link with the switch. I have tried auto negotiate, forcing both sides the 10G. No success. If I set the card to auto and plug into a 1G port, same results. NIC supports 1,2.5,5,10G. I have tried several cables Cat6, 7' long. If I use the same cable and plug NIC into a netgear switch, it immediately links at 1G and passes traffic. I upgraded my switch firmware to v2.00(ABWE.1)C0, no change. I have verified I have the latest driver from ASUS for the NIC. Any suggestions?

    Hi @cozman,

    Could you help provide some clarification?

    1. Did you check the per port status on switch web GUI? Is the switch port linked down?
    2. Please help to connect a loop on the switch. If neither of the ports can't link up, this could be a device hardware issue. In addition, the XGS1250-12 enable loop prevention by default, therefore, you will find only one port is linked up in the web page.
    3. Please help to check if the switch front panel has an LED ECO mode button. If so, please check if the LED ECO mode is enabled/on in Management tab. Or, help to press it for 5 seconds and then release. LED ECO mode will change the link LED to be disabled when the link status is up.

    Update:

    Please also check:

    1. Please check if the IEEE 802.3az EEE is disabled. If not, please disable it and reconnect again. EEE might affect the connection.
    2. May I know if the XGS1250-12 connect to the netgear switch will link up? Or have you tried to connect other devices to XGS1250-12?

    1. Yes, showing enabled, but down.
    2. Looped ports, no change or link. Both show down.
    3. Verified eco mode is off. Other link lights working fine.
    4. IEEE 802.3az EEE is disabled.
    5. Netgear is linked and passing traffic, as are all the 1G ports. Ports 11 & 12 are also working as expected.

    Hi @cozman,

    Since answer 2 and 5 looks like conflict, may I clarify more details?

    1. Could you help to screenshot the per port status when doing port loops? Or take a photo of switch front panel for port Link LED status.
    2. About answer 5, do you mean XGS1250 connect to Netgear will link up and works on all of ports? (XGS1250-12 port 1 to port 12)

    When looped, no link lights on either port and GUI shows both down. To clarify, port 1 is uplink to Netgear, linked at 1G full working properly. Ports 2 - 8 work as expected. Nothing on ports 9 & 10. 11 is linked at 10g full. 12 is a DAC cable, linked at 10G full. If I move cable from 11 to 10, no activity on switch. No link light and GUI shows down. It appears that ports 9 & 10 are just dead or inoperable. Let me know if you still need screenshot.

    Hi @cozman

    Thanks for the details. Sorry we had a typhoon vacation, so the reply was delayed. The result shows port 9 - 10 has hardware issue. Please help to submit RMA ticket via this path:
