ABSTRACT:
A method, medium and implementing processing system are provided for controlling the number of Ethernet adapters connected in an EtherChannel depending upon the current bandwidth requirements of the system. This system reduces power consumption, inter alia, wherever possible while not sacrificing performance or flexibility of an EthernetChannel. An exemplary embodiment EtherChannel's total bandwidth utilization is monitored and controlled. When the bandwidth utilization is a predetermined amount less than or more than a predetermined threshold level, power supplied to one or more of the physical Ethernet adapters that are part of the EtherChannel is adjusted, i.e. reduced or increased, accordingly. In another embodiment, in systems where ethernet devices support different levels of power, the power supplied to one or more adapters can be systematically incrementally reduced or increased in response to reduced or increased bandwidth utilization.
