Auto MDI/MDI-X:A Medium Dependent Interface (MDI) describes the interface (both physical and electrical) in a computer network from a physical layer implementation to the physical medium used to carry the transmission. Ethernet over twisted pair also defines a medium dependent interface crossover (MDIX) interface. Auto-MDIX ports on newer network interfaces detect if the connection would require a crossover, and automatically chooses the MDI or MDIX configuration to properly match the other end of the link.
Yes
Broadcast storm control:
Yes
Flow control support:
Yes
Link aggregation:
Yes
Rate limiting:
Yes
Spanning tree protocol:
