Hi alex_qt,

 

 

Thank you for posting at Wired Communities. Have you tried change the cable to test and switch to other switch port to test?

 

 

Thanks,

Yes I test cable and its ok. Also I plug in cables n different port in switch with no luck. In this time I haven't different switch so can't test switch itself.

Hi Alex_qt,

 

 

Thank you for the updated. The link down is intermittent, just to double check any changes made on the system or switch recently prior this issue occur?

 

 

Thanks,
