Product and Software: This article applies to all Aruba Instant Access Points (IAP's) running Aruba InstantOS 184.108.40.206-220.127.116.11.
Local Probe Request Threshold is a configuration feature in SSID settings, that allows you to control whether or not a BSSID of an IAP should respond when a client sends a broadcast probe request frame to search for all available SSIDs.
This works by looking into the RSSI of the incoming probe request. If the RSSI of the incoming request is below the configured threshold value, then the probe request will get ignored.
The supported range of Received Signal Strength Indication (RSSI) values is 0-100 dB. By default, this feature is disabled with a value of zero (0).

1. Login into Instant WebUI
