Green AP

Green AP is a feature that helps save energy consumption from common equipment in various areas like airports, offices, universities, hotels and so on. Based on the feeds, the Green AP feature dynamically enables, disables, or reduces functionality of an allocated AP to reduce the consumption of energy.

NetInsight provides the feed for ArubaOS to move the APs into deep-sleep mode or to wake up the APs from deep sleep mode. ArubaOS is responsible for maintaining the state of the APs and forwarding the AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. telemetry in different state.

In a Campus AP Campus APs are used in private networks where APs connect over private links (LAN, WLAN, WAN or MPLS) and terminate directly on controllers. Campus APs are deployed as part of the indoor campus solution in enterprise office buildings, warehouses, hospitals, universities, and so on. setup, the Mobility Master will communicate between NetInsight and the APs. For example, if NetInsight determines that a list of APs are to be put in deep-sleep or power saving mode, NetInsight sends the list to Mobility Master and then, the Mobility Master forwards the request to the APs through the managed device. The AP then, decides to either accept or reject the deep sleep request and sends the status back through AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. messages to the Mobility Master. This is again communicated to NetInsight.

The APs will not fall into deep-sleep mode in the following scenarios:

• The AP does not support WoL functionality.
• In MultiZone where APs need to provide wireless services for Datazone.
• The AP is preloading image.
• The AP is writing flash
• The APs have pending STAs.
• Wired AP is enabled on an AP.
• AP is 802.1X 802.1X is an IEEE standard for port-based network access control designed to enhance 802.11 WLAN security. 802.1X provides an authentication framework that allows a user to be authenticated by a central authority. enabled.

Before the AP falls into deep-sleep mode, it performs the following actions:

• Bring down all the virtual APs.
• Send a warning syslog message
• Remove all connections to managed devices.
• Set the reboot reason. This is set to ensure that when the AP wakes up from the deep-sleep mode, this reboot reason indicates that the AP has recovered from deep-sleep mode.
• AP falls into deep-sleep mode.

Whenever the AP wakes up from the deep-sleep mode, the AP gets rebooted and the reason for the reboot is logged as, AP is waken up from deep-sleep mode.

AP-514, AP-515, AP-534, AP-535, AP-555, AP-504, AP-505, AP-505H, AP-518, and 570 Series access points support the Green AP, a power saving feature.

Limitations

Green AP feature is not supported for the following:

• Legacy APs without WoL support
• Instant APs
• Remote APs
• Mesh portals and mesh points
• Stand-alone controllers deployment

Configuring Green AP

The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands configure the green AP. These CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands are not available on the managed device and stand-alone controller deployment.

The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands display the APs in the deep-sleep mode. A new flag, p is introduced to show that the AP is in deep sleep mode:

The following CLI Command-Line Interface. A console interface with a command line shell that allows users to execute text input as commands and convert these commands to appropriate functions. commands display all the pending APs in the per-md list, sends the AP_INFO AMON Advanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. message for a particular AP, and tracks Green AP related counters:

The show ap greenap counters command can be used for debugging as it displays information such as such how many deep-sleep requests from Netinsight are received, and how many requests are dropped and so on.
