1. Explanation on Spectrum Monitors and its types.
2. Spectrum Monitor configuration on IAPs

Aruba Instant AP can now be configured as spectrum monitor from OS version 6.1.3.4-3.1 onwards.  Currently this feature is supported on IAP104/105/134/135 platforms. IAP 92/93 cannot be configured as Spectrum Monitors. This list may increase with the release of new IAP models in future.

Spectrum Monitors can be of two types:

1. Hybrid mode or Background Spectrum mode - In this mode, the spectrum monitor runs in the background while providing access to the client.  If any IAP in the Instant network does not support the spectrum monitoring feature, that AP continues to function as a standard IAP, rather than a hybrid IAP. By default, the background spectrum monitoring option is disabled. In the hybrid mode, spectrum monitoring is performed only on the home channel.
2. Spectrum Monitor mode - In this mode, the AP becomes a dedicated spectrum monitor and would not service any client.

Environment : This article applies to IAP104/105/134/135 platforms running 6.1.3.4-3.1 and 6.2.0.0-3.2. Any version prior to these does not have this feature.

1. To configure IAP as dedicated spectrum monitor:

1. Select the AP, and click on “edit”.
2. In “Radio” tab, select “Spectrum Monitor” for mode.
3. Reboot the AP to make it work.

2.  To configure IAP as Hybrid or Background mode Spectrum Monitor:

1. Click on “RF”, then click “Show advanced option” to view “Radio” tab.
2. Select “Enabled” under Background Spectrum Monitoring to enable hybrid mode for 2.4 and as 5Ghz. If this option is disabled, the AP will operate as a dedicated spectrum monitor and will not serve any client.
