Specify a number from 0-23 to select the hour during which AirMatch updates are sent to the APs (in 24-hour format). If the managed device to which the AP is associated is in a different time zone than Mobility Master, the AirMatch solution will be deployed according to the time zone of the managed device.

AirMatch channel planning evens out channel distributions in any size of network, and in any subset of the contiguous network (as much as allowed by the network configuration, regulatory domain and AP hardware capability). AirMatch also minimizes channel coupling, where adjacent radios are assigned to the same channel. The computing power of Mobility Master impacts channel distribution calculations, so channel coupling may occasionally be allowed in complex networks to keep the computing time practical.

AirMatch Channel Assignments

Each AP in a Mobility Master deployment measures its RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. environment for a five minute period, every 30 minutes, by default. The AP then sends AMONAdvanced Monitoring. AMON is used in Aruba WLAN deployments for improved network management, monitoring and diagnostic capabilities. messages about the radio feasibility to the managed device based on thehardware capability for the AP, radio and regulatory domain, and RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. neighbors. The managed device forwards these messages to the Mobility Master. The Mobility Master adds this information to a database, computes an optimal solution, and deploys the latest RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. plan by sending updated settings to the APs. By default, this configuration update is sent at 5 AMAir Monitor. AM is a mode of operation supported on wireless APs. When an AP operates in the Air Monitor mode, it enhances the wireless networks by collecting statistics, monitoring traffic, detecting intrusions, enforcing security policies, balancing wireless traffic load, self-healing coverage gaps, and more. However, clients cannot connect to APs operating in the AM mode. (as per the Mobility Master system clock), but time of this configuration update can be modified via the AirMatch profile.

 

An exception to this daily update is an automatic channel change due to a radar detection event or high noise interference. If an AP detects a radar event on its current operating channel, that AP automatically changes to another supported channel to avoid radar interference, and does not wait for the daily RFRadio Frequency. RF refers to the electromagnetic wave frequencies within a range of 3 kHz to 300 GHz, including the frequencies used for communications or Radar signals. configuration update from the Mobility Master. An AP may also automatically change channels if a very high noise level is detected on the current channel, if at least one other channel is free of noise.

In ArubaOS 8.0, AirMatch moves a radio to a random channel when a radar event is detected, or if a high noise floor is detected on a non-static channel. Starting with ArubaOS 8.0.1, AirMatch uses the criteria described in Table 1 to assign a new channel.

Table 1: Channel Assignment Logic

Issue Prompting Channel Change

Channel Selection Criteria

Detected radar

AirMatch selects a channel with a minimum interference index from the channels without high noise or a radar condition.

High channel noise

The channel selection criteria varies between static and non-static channels.

If static channel is configured, the channel does not change due to a high noise condition.

For a non-static channel, AirMatch selects a channel with a minimum interference index from the channels without high noise or a radar condition.

Channel Quality Improvement Thresholds

ArubaOS 8.0.1 introduces the AirMatch channel quality improvement threshold, which allows you to select the minimum channel improvement that can trigger a new scheduled channel solution. The default threshold value is a 15% improvement. If a proposed channel change will not produce an improvement that meets or exceeds this threshold, AirMatch will not trigger a channel change.

This channel quality setting only applies to scheduled updates. If you manually trigger an update using the airmatch runnow command, AirMatch will deploy the new solution regardless of the level of improvement.
