Hello, are you already running latest PT.02.11 on your HPE OfficeConnect 1820 (J9981A)? I don't see any particular Tx/Rx or Collision errors on the Port Summary Statistics screenshot ("w/o" means "without" so the meaning of errors Tx/Rx columns with non zero values is "without errors").
Edit: read this, it seems that a similar logged events were fixed by just upgrading a 1820 to PT.02.05 (now well superseeded by current software version).
Edit: for current software version have a look here.
