dot11AuthenticateFail
Module: IEEE802dot11-MIB
OID (symbolic): IEEE802dot11-MIB::dot11AuthenticateFail
OID (numeric): 1.2.840.10036.1.6.0.3
Node type: NOTIFICATION-TYPE
Description: The authenticate failure notification shall be sent when the STA sends an Authentication frame with a status code other than 'successful'. The value of the notification shall include the MAC address of the MAC to which the Authentication frame was sent and the reason for the authentication failure.
ifIndex - Each 802.11 interface is represented by an ifEntry. Interface tables in this MIB module are indexed by ifIndex.
What is dot11AuthenticateFail?
This notification is triggered when a wireless station (STA) sends an authentication frame to an 802.11 access point but the authentication fails—for example, due to invalid credentials or unsupported security methods. The notification includes the MAC address of the device that failed authentication and the reason code explaining why the attempt was rejected. A network operator monitors these events to detect unauthorized access attempts or diagnose wireless connection problems.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' IEEE802dot11-MIB::dot11AuthenticateFail snmptrap -v2c -c public <manager> '' 1.2.840.10036.1.6.0.3
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
Example snmptrapd log entry:
