Enables or disables EEE on the physical layer.
|
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 |
Off.
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.
The following example turns the EEE feature on for port 2:
config port 2 eee on
This command was first available in ExtremeXOS 15.4.
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.
