dot1xAuthAuthFailWhileAuthenticating
Module: IEEE8021-PAE-MIB
OID (symbolic): IEEE8021-PAE-MIB::dot1xAuthAuthFailWhileAuthenticating
OID (numeric): 1.0.8802.1.1.1.1.2.3.1.6
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Counts the number of times that the state machine transitions from AUTHENTICATING to HELD, as a result of the Backend Authentication state machine indicating authentication failure (authFail = TRUE).
What is dot1xAuthAuthFailWhileAuthenticating?
This counter increments each time the IEEE 802.1X port authentication state machine transitions from the AUTHENTICATING state to the HELD state due to authentication failure (invalid credentials or unreachable authentication server). It tracks authentication failures specifically during the active authentication attempt, not other failure modes. Network security teams monitor this to detect intrusion attempts, configuration errors, or authentication server issues affecting port access control.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.0.8802.1.1.1.1.2.3.1.6 snmpwalk -v2c -c public <target> IEEE8021-PAE-MIB::dot1xAuthAuthFailWhileAuthenticating
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.0.8802.1.1.1.1.2.3.1.6.1 snmpget -v2c -c public <target> IEEE8021-PAE-MIB::dot1xAuthAuthFailWhileAuthenticating.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> dot1xAuthAuthFailWhileAuthenticating.1
