configure ports eee

configure ports port_list eee [on | off]

Description

Enables or disables EEE on the physical layer.

Syntax Description

port_list

Specifies one or more ports or slots and ports.

on Specifies that the port advertises to its link partner that it is EEE capable at certain speeds

off

Specifies that the port advertises to its link partner that it is not EEE capable at certain speeds

Default

Off.

Usage Guidelines

Use this command to enable EEE on the switch. The keyword on specifies that the port advertises to its link partner that it is EEE capable at certain speeds. If both sides, during auto-negotiation, determine that they both have EEE on and are compatible speed wise, they will determine other parameters (how long it takes to come out of sleep time, how long it takes to wake up) and the link comes up. During periods of non-activity, the link will shut down parts of the port to save energy. This is called LPI for low power idle. When one side sees it must send something, it wakes up the remote and then transmits.

Example

The following example turns the EEE feature on for port 2:

config port 2 eee on

History

This command was first available in ExtremeXOS 15.4.

Platform Availability

EEE is supported on the following Extreme Networks platforms:
  • 4120, 4220, ExtremeSwitching 5320, 5420, 5520, 5720, and 7520-48XT—copper 10/100/1000 and multi-rate ports
Note

Note

There are hardware limitations on EEE at 2.5 Gbps and 5 Gbps speeds on 4220 Series and ExtremeSwitching 5720 Series switches. See the topic Energy Efficient Ethernet in the Switch Engine User Guide for your version of Switch Engine for more information.
