Ethernet link transmit power and rate adjustment based on alien crosstalk feedback

A network switch comprising:

• a plurality of Ethernet ports having their respective Physical (PHY) Layers interconnected via a common interface local to the network switch, the common interface being configured to pass local information among respective PHY layers of the Ethernet ports of the network switch, the Ethernet ports being configured to transmit data over wired Ethernet connections to remote network devices;
• one or more receivers configured to 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 configured to adjust for the first Ethernet port, 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;
• and
• a first transmitter configured to transmit data via the first Ethernet port according to the second data rate and/or the second transmit power level.
