3.1.10.2 Crossover Cable
A crossover cable connects an MDI device to another MDI device, or an MDI-X device to another MDI-X device. The
following diagram shows a typical crossover cable connection between two switches or hubs (two MDI-X devices).

3.1.11 AUTO-NEGOTIATION
The KSZ8765CLX conforms to the auto-negotiation protocol as described by the 802.3 committee. Auto-negotiation
allows unshielded twisted pair (UTP) link partners to select the highest common mode-of-operation. Link partners adver-
tise their capabilities to each other and then compare their own capabilities with those they received from their link part-
ners. The highest speed and duplex setting that is common to the two link partners is selected as the mode-of-operation.
Auto-negotiation is supported for the copper ports only.
