This read-only Counter32 counts RADIUS packets received from this server on the authentication port that were dropped for reasons other than being malformed, having a bad authenticator, or being an unknown type. Admins use it as a catch-all indicator of authentication-path packet loss on the client side, worth checking when accept and reject counts seem lower than expected relative to requests sent. For example, persistent drops recorded in wwpRadiusClientPacketsDropped despite low retransmissions and timeouts might point to a local resource issue on the client, such as a full receive buffer.
