What is etsysNacApplAuthenticationFailures?
A Counter64 counting the authentication attempts the NAC Appliance has rejected since it was started. A rising rate of this counter is the primary signal admins watch for credential problems, misconfigured supplicants, or an active brute-force attempt against the NAC. An admin polling this OID and seeing it jump from 40 to 400 within an hour would investigate whether a specific switch or VLAN is generating a wave of bad login attempts.
