Trap Buffer Description

Failed to login through SNMP.(IPAddressType=[IPAddressType], IPAddress=[IPAddress], ReasonInfo=[ReasonInfo].)

An authenticationFailure trap signifies that the SNMP entity, acting in an agent role, has received a protocol message that is not properly authenticated. While all implementations of the SNMP must be capable of generating this trap, the snmpEnableAuthenTraps object indicates whether this trap will be generated.

In VS mode, this trap is supported only by the admin VS.

Impact on the System

Cause 2: Authentication password or privacy password is incorrect.

Procedure

2. For SNMPv3, verify if the USM User is configured in the SNMP Agent, then log in to the SNMP Agent with the correct user name and password.
