Auto-negotiation performs at power-up, on command from the LAN controller, on detection of a PHY error, or following Ethernet cable re-connection. During the link establishment process, both link partners indicate their EEE capabilities. If EEE is supported by both link partners for the negotiated PHY type, EEE functions independently in either direction. Changing the EEE configuration resets the interface because the device restarts Layer 1 auto-negotiation. You may want to enable Link Layer Discovery Protocol (LLDP) for devices that require longer wake-up times before they are able to accept data on their receive paths. Doing so enables the device to negotiate extended system wake-up times from the transmitting link partner. NOTE: The EEE feature is applicable only for Base-T switches. Enable energy-efficient Ethernet EEE is disabled by default. To reduce power consumption, enable EEE. 1.
