the rate and the duplex mode are not simultaneously specified for an electrical Ethernet
interface, the electrical Ethernet interface operates in the auto-negotiation mode.
No matter whether an electrical Ethernet interface operates in the forced or auto-negotiation

RJ-45 connector
The 10Base-T/100Base-TX/1000Base-T electrical Ethernet interfaces of the device use RJ-45
connectors and support MDI/MDI-X auto-sensing. Category-5 twisted pair cables are used for
RJ-45 connectors.
