Minimum security level for trap processing

You can define which traps and informs the probe processes based on their security credentials.

In SNMP V3 each trap and inform is associated with a user (endpoint) and users are defined in the configuration files (see Configuration files). Each user has one of three security levels determined by their definition in the configuration files:

Table 1. Security levels for SNMP V3 users for traps and informs
Security level Description

NoAuth

There is no authentication type and no privacy type defined for the user.

AuthNoPriv

The user has an authentication type but no privacy type.

AuthPriv

The user has both an authentication type and a privacy type.

By default, the probe processes all traps and informs regardless of the security level of their users. However, you can use the snmpv3MinSecurityLevel property to define which traps and informs the probe processes based on the security level of their users. The property can take the following values:
