This counter counts Access-Accept responses received for command/session authorization requests, meaning the TACACS+ server granted permission for whatever action the switch asked about, whether or not the response was itself well-formed. A healthy admin session generates a steady stream of accepts as each permitted command clears authorization, so a session where AccessRequests keeps climbing but this counter stalls indicates the server is denying rather than granting most attempted commands. For example, a junior admin's account restricted to read-only commands would generate many authorization requests but comparatively few accepts.
