SNMP V3 support

The probe supports SNMP V3 traps and informs using User-based Security Model (USM) for authentication and privacy. USM requires that you specify a user that can log on to the probe for each security name from which the probe receives traps. You also specify a unique user or engine ID for each trap source from which the probe receives traps.

The probe stores information on users in configuration files. It uses the information in these files when it starts up to load the necessary data, which is determined by two probe properties.

This section contains information on the following topics:

  • Configuration files
  • Probe properties
  • Defining the startup behavior
  • Adding new users to the configuration file
  • Traps and informs
  • Probe initialization
  • Limiting processing to SNMP V3 only
  • Minimum security level for trap processing

In addition, there is an example of configuring a probe for SNMP V3.

Note: When the probe is running SNMP V3, it is compatible only with FIPS 140-2 if it is using AES and SHA.
