Crossover Cable
A crossover cable connects an MDI device to another MDI device, or an MDI-X device to another MDI-X device. Figure 2
shows a typical crossover cable connection between two switches or hubs (two MDI-X devices).
Figure 2. Typical Crossover Cable Connection
Auto-Negotiation
The KSZ8864RMN 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
advertise their capabilities to each other, and then compare their own capabilities with those they received from their link
partners. The highest speed and duplex setting that is common to the two link partners is selected as the mode of
operation.
The following list shows the speed and duplex operation mode from highest to lowest.
Highest: 100Base-TX, full-duplex
High: 100Base-TX, half-duplex
Low: 10Base-T, full-duplex
Lowest: 10Base-T, half-duplex
