Determining EEE Capability

To determine whether a line card supports EEE, use the show interface capabilities module module
command, as follows:
Switch# show interface capabilities module 3
GigabitEthernet3/1
Model:
Type:
Speed:
Duplex:
Auto-MDIX:
EEE:
Enabling EEE
To enable EEE on a given port, use the power efficient-ethernet auto command.
Command
Step 1
Switch# configure terminal
Step 2
Switch(config)# interface interface
Step 3
Switch(config-if)# power efficient-ethernet auto
Step 4
Switch(config-if)# exit
The following example shows how to enable EEE:
Switch# config t
Switch(config)# interface gigabitethernet 1/1
Switch(config-if)# power efficient-ethernet auto
Switch(config-if)# exit
Determining EEE Status
To determine EEE status use the show platform software interface interface status command:
The following example determines EEE status:
Switch(config)# show platform software interface g2/1 status
Switch Phyport Gi2/1 Software Status
EEE: Disabled
