when I checked the interface inventory, is displaying "Qualified"-->"False"

Hi, please check these steps:

To troubleshoot the connectivity issue, you can follow these steps:

  1. Check the cable connections to ensure they are properly inserted into the port.
  2. Verify that the port is enabled by checking the configuration.
  3. Ensure that the port is not administratively down by checking the administrative status.
  4. Check for any fault conditions that may have caused the port to be shut down.
  5. Verify that the port has not been shut down due to a security violation.

If still the issue persists, it might be that the interface is not up because the SFP module is not qualified by the server.

Erman Özkurt, Thank you for your support,

I found the error that the  SFP module is not support third party SFP by the power switch(Z9264F-ON). When I was tested by the Dell module SFP, it worked properly as you said.

No Events found!
