eee

Enables Energy-Efficient Ethernet (EEE) on the selected GE port. The IEEE 802.3az standard, also known as EEE, defines a set of enhancements that allows physical layer transmitters to consume less power when they are in a state of idleness or low data activity. By enabling EEE, you allow the network port to switch between an active mode (during data transmission) and idle mode (when there is no Ethernet traffic).

IEEE 802.3az refers to this state of idleness as Low Power Idle (LPI). When enabled, in the LPI mode, both ends of the Ethernet link disable operating circuitry that are not needed and save power.

Note

Note

Energy-Efficient Ethernet can be activated only if devices at both ends of the physical link support EEE.

Supported in the following platforms:

  • Access Points — AP505i, AP510i/e, AP560i

Syntax

eee

Parameters

none

Example

ap505-13403B(config-device-94-9B-2C-13-40-38-if-ge2)#eee
The following command shows the state of Energy-efficient Ethernet, where:
  • Enable: Indicates if Energy-Efficient Ethernet is enabled or disabled on the selected physical port. A value of '1' indicates enabled and '0' indicates disabled.
  • Active: Indictaes if Energy-Efficient Ethernet is active or inactive on the selected physical port. A value of '1' indicates EEE is active and '0' indicates inactive. Note, will be active only if the devices on both ends of the phhysical link support EEE.
