to exchange network capabilities between two Ethernet nodes. The exchange
|
||
|
|
takes place at power-up (or link reset) time. It automatically establishes
|
||
|
|
a link that takes advantage of the highest common denominator of the mutual
|
||
|
|
capabilities of the two Ethernet nodes. The universal mechanism negotiates
|
||
|
|
capabilities that include link speed, PHY types, and full duplex or half duplex.</dd>
