Users Guide

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. Enter the physical Ethernet interface information in CONFIGURATION mode.
interface ethernet node/slot/port[:subport]
2. Enable EEE in INTERFACE mode.

Clear EEE counters
You can clear EEE counters on physical Ethernet interfaces globally or per interface.

View EEE status/statistics
You can view the EEE status or statistics for a specified interface, or all interfaces, using the show commands.
