In the Preference Mode field, select a radio button to determine whether the port should act as the Master or Slave during auto-negotiation. This field is only available if auto-negotiation is enabled. Configuring the port as a master causes it to control and impose its settings on the remote port, and vice-versa. The Neighbor Advertisement displays the advertised capabilities of the remote port. Помог пункт  Preference Mode Спасибо!
