Abstract

A system and method for energy savings on a PHY/MAC interface for energy efficient Ethernet. Power savings for a PHY due to low-link utilization can also be realized in the higher layer elements that interface with the PHY. In one embodiment, subrating is implemented on a MAC/PHY interface to match a subrating of the PHY with a remote link partner. This subrating is less than the full capacity rate and can be zero.
