Question- What is the usage of AP Power Mode or ap-poe-power-optimizationon AP-220 Series
Environment- In scenario where we need to disable the Ethernet 1 port and USB and make the AP runs in reduced power level.
Answer- Starting with ArubaOS 6.3.1.10, a new configuration parameter ap-power-mode is introduced. This parameter is available under the ap provisioning-profile command. When this parameter is set to overriden, the controller disables the USB and the Ethernet (eth1) ports of AP-220 Series access points. Once the ports are disabled, the AP runs in reduced power mode.
In the CLI:
Use the following commands to configure an AP to run in reduced power mode using the CLI:
(host) (config) #ap provisioning-profile default
(host) (Provisioning profile "default") #ap-power-mode overridden
Use the following command to verify the configuration using the CLI:
(host) (config) #show ap provisioning-profile default
Provisioning profile "default"

AP power mode overridden <--
Important Points to Remember:
- By default, the AP operates in normal mode with the USB and Ethernet ports enabled.
- Changing the ap-power-mode parameter requires a reboot of the AP.
- In case the AP has an external DC power source, the USB and Ethernet (eth1) ports are not disabled even after setting the ap-power-mode to overriden.
- Overriding the AP power mode sets the maximum power request for LLDP TLV to 17.1W instead of 19.0W.
Starring from 6.3.1.11, the ap-power-mode parameter under ap provisioning-profile is renamed to ap-poe-power-optimization.
In the CLI
Use the following commands to configure an AP to run in reduced power mode using the CLI:
(host) (config) #ap provisioning-profile default
(host) (Provisioning profile "default") #ap-poe-power-optimization enabled
Use the following command to verify the configuration using the CLI:
(host) (config) #show ap provisioning-profile default
Provisioning profile "default"
