Dynamic Management of Energy Efficient Ethernet Feature

Abstract

Devices, systems, methods, and processes for controlling dynamic disablement and re-enablement of an Energy Efficient Ethernet (“EEE”) feature in network devices are described herein. In a network device, the EEE feature is default enabled on each port. A link partner associated with a port is detected and a set of EEE parameters associated with the link partner is determined. The set of EEE parameters includes an EEE capability of the link partner and/or a link quality of a link between the port and the link partner. The EEE feature on the port is disabled on the port based on the link quality being below a threshold, the EEE capability being disabled, the EEE capability being different from that of the port, or the EEE capability being disagreed between the network device and the link partner. The EEE feature is reenabled a predefined time period after the disablement.
