z
When 10/100 Mbps and half/full duplex mode are specified for an electrical Ethernet interface, the
electrical Ethernet interface operates in the forced mode. When 1000 Mbps or the speed and the
duplex mode are not simultaneously specified for an electrical Ethernet interface, the electrical
Ethernet interface operates in the auto-negotiation mode.
z
No matter whether an electrical Ethernet interface operates in the forced or auto-negotiation mode,
it supports automatic MDI/MDIX.
