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: WS-X4748-NGPOE+E-RJ-45
Type: 10/100/1000-TX
Speed: 10,100,1000,auto
Duplex: half,full,auto
Auto-MDIX: yes
EEE: yes ( 100-Tx and 1000-T auto mode )
Enabling EEE
To enable EEE on a given port, use the power efficient-ethernet auto command.
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
Command Purpose
Step 1
Switch# configure terminal Enters configuration mode.
Step 2
Switch(config)# interface interface
Enters interface configuration mode and
specifies the port to be configured.
Step 3
Switch(config-if)# power efficient-ethernet auto
Enables EEE.
Step 4
Switch(config-if)# exit Exits global configuration mode.
