Verifying That EEE Is Saving Energy on Configured Ports

Purpose

Verify that enabling EEE saves energy on Base-T Copper Ethernet ports.

Action

You can see the amount of energy saved by EEE on an EX Series switch using the show chassis power-budget-statistics command.

1. View the power budget of an EX Series switch before enabling EEE.

Meaning

On an EX6210 switch, the Power Used field in the output shows the actual power being consumed by the line card or SRE module, including PoE power. If you compare the values in the Power Used field before and after enabling EEE for FPC 3 and FPC 7, you will notice that power is saved when EEE is enabled.

Note: The Power Used field is displayed in the output only for EX6210 switches.

On an EX4300 switch, if you compare the values in the Non-PoE power being consumed field before and after enabling EEE, you will notice that power is saved when EEE is enabled.
