authFailIPAddress
Module: RMONitor-MIB
OID (symbolic): RMONitor-MIB::authFailIPAddress
OID (numeric): 1.3.6.1.4.1.2.6.45.1.3.1.2
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-only
Description: The IP address of the manager that sent the SNMP request that caused the authentication failure.
What is authFailIPAddress?
This object records the IP address of the manager whose SNMP request was rejected due to failing authentication against the authentication table. Admins check this to identify the source of unauthorized access attempts, whether from a misconfigured legitimate tool or a potential intrusion attempt. For example, seeing repeated authFailIPAddress entries from the same unexpected address like 203.0.113.50 would warrant investigating that host.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.6.45.1.3.1.2 snmpwalk -v2c -c public <target> RMONitor-MIB::authFailIPAddress
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2.6.45.1.3.1.2.1 snmpget -v2c -c public <target> RMONitor-MIB::authFailIPAddress.1
