Module: IEEE8021-PAE-MIB

OID (symbolic): IEEE8021-PAE-MIB::dot1xAuthBackendAuthFails

OID (numeric): 1.0.8802.1.1.1.1.2.3.1.18

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: Counts the number of times that the state machine receives an EAP-Failure message from the Authentication Server (i.e., aFail becomes TRUE, causing a transition from RESPONSE to FAIL). Indicates that the Supplicant has not authenticated to the Authentication Server.

What is dot1xAuthBackendAuthFails?

This counter records how many times the authentication server rejected a supplicant's credentials by sending an EAP-Failure message during the 802.1X port access control process. It indicates failed authentication attempts where clients provided invalid credentials or failed remote authentication checks. An operator would monitor this counter to identify security issues, troubleshoot authentication problems, or detect possible unauthorized access attempts.
