Product and Software: This article applies to all Aruba Instant Access Points (IAP's) running on Aruba InstantOS or later.

"Authentication Survivability"  is a newly added feature starting from InstantOS version This feature provides authentication and authorization availability against remote link failure for Instant Access Point, when working with ClearPass Policy Manager. 

When enabled, this feature allows Instant to authenticate the previously connected clients using EAP-PEAP authentication against cached credentials information, even when connectivity to 
ClearPass Policy Manager is temporarily lost. By default, the credentials are cached for 24 hours.

NOTE: If both the IAP to which the client was associated and the CPPM (ClearPass Policy Manager) are not available, then the client will be not be able to reauthenticate until the CPPM server is available again
On GUI, this feature is a part of authentication configuration while creating a new SSID. Below image helps us to enable the option while creating a new SSID or modifying an existing one.
