Q. What is an uplink port and what are the ways to connect two hubs/switches together?

A. There is no big mystery about the difference between an uplink and a regular port. Each Ethernet interface has two transmit pins + and - and two receive pins (the other pins may have wires running between them, but they are not used). The transmit pins at one end of a cable have to be connected to the receive pins at the other end and vice versa. An uplink port does not crossover the transmit and receive pins and a regular port does.

In addition to Answer #1: Sometimes "Uplink" ports have higher speed, than regular ports. For example, in some hubs/switches you may have 10 MBit speed at regular ports, and 100 MBit Full Duplex at Uplink Port. And "low end" new switches have 10/100 regular ports and 1 GigaBit uplink ports. Plus, in advanced switches you may have different config and logic.

But in a few words, purpose of Uplink Port is to interconnect hetwork devices.

Good luck,
