To fix the 10G SFP+ port link issue, with the fiber transceiver, please check the DDMI of the issue port first.
If the current operating parameters of the issue port are out of the high/low range, please have a cross-test, change the fiber/change the SFP transceiver/change the SFP port, to check this issue.
If the switch cannot display the SFP transceiver information, the SFP transceiver or SFP port has an issue. Please change the SFP transceiver/change the SFP port to check.
If the issue still exists, please navigate to the Nebula category to raise your problem.
