AP Power Mode/ap-poe-power-optimization

Aruba Employee

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"

Password of AP so that AP can authenticate to 802.1x using PEAP N/A
Uplink VLAN 0
USB power mode auto
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"

Hello

Is this just for the AP-220 series or does it also apply to the new 205H series? We're trying to force the AP's to just use 802.11af as the PoE budget isn't big enough for all AP's to do 802.11at at the this.

 

Would we just apply this profile to the default ap-group and the final ap-group with this change, or would we need to include the other parameters as well? Like RemoteAP and serverip
