In version 6.3 GS2 and in 6.4 or greater, it's possible to limit AirWave to gather data for only one SSID. To do that, you can enable the feature in one database field, and specify the one SSID in another. Here's an example of how to do that:
# dbc "update seas_config set ssid_limiting_enabled = 1"
# dbc "update seas_config set visible_ssid = 'My Visible SSID'"
This does nothing to hide data that's already been gathered for other SSIDs. That data will be aged out based on the AMP Setup page's Inactive SSID data purging setting.
