Viewing Detected Client Pre-Authentication History
To help authenticated clients roam without losing sessions and needing to re-authenticate, wireless clients can
attempt to authenticate to other APs within range that the client could possibly associate with. For successful
pre-authentication, the target AP must have a VAP with an SSID and security configuration that matches that
of the client, including MAC authentication, encryption method, and pre-shared key or RADIUS parameters.
The the AP that the client is associated with captures all pre-authentication requests and sends them to the
switch.
The Detected Client Pre-Authentication History page shows information about the pre-authentication
requests that the detected client has made.
