This OID represents an alarm notification triggered when a user fails to authenticate using TACACS+ (a centralized authentication system). It indicates a failed login attempt. A security team would receive this alert to investigate unauthorized access attempts.
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> '' RAPID-CITY::rcnTacacsAuthFailure snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2272.1.21.0.74
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
