Abstract
A network switch includes a plurality of Ethernet ports having their respective Physical (PHY) Layers interconnected via a common interface local to the network switch. The common interface passes local information among respective PHY layers of the Ethernet ports. One or more receivers receive for a first Ethernet port, over the common interface, information indicative of alien cross talk affecting at least one second Ethernet port of the network switch. A transmission attribute controller adjusts, based on the received information indicative of alien cross talk affecting the at least one second Ethernet port of the network switch, a first data rate and/or a first transmit power level to a second data rate and/or a second transmit power level for transmitting data to a remote network device. A first transmitter transmits data via the first Ethernet port according to the second data rate and/or the second transmit power level.
