Unified Assurance Event SNMP Trap Aggregator Basics

Overview

The Unified Assurance Event SNMP Trap Aggregator is a generic SNMP Trap message listener that receives messages from devices, parses the results with customizable rules and creates de-duplicated events within Unified Assurance.

A default installation includes a set of rules files for processing a variety of traps from numerous different vendors. The following links provide you with more information regarding supported devices and a greater level of detail about the Event SNMP Trap Aggregator:

SNMP Trap Aggregator Setup

  1. Review the logic in the rules files referenced in the configuration to see the processing that will be done when traps are received:

    • LoadRules will be executed during application startup to load data that might be needed during processing.

    • IncludeRules will be read during application startup to load additional files that might be called during processing.

    • BaseRules will be executed for each device that is selected based on the configuration.

    Update the logic as needed.

  2. Enable the default Service, unless a specific configuration option is needed.

    Configuration -> Broker Control -> Services

  3. Configure devices to send SNMP Trap messages to the server where the SNMP Trap Aggregator has been started.

SNMPv3 Setup

A SNMP Access Profile must be created with the same credentials configured on the sending devices. Multiple SNMP Access Profiles can be setup to match different credential sets.

  1. Go to the SNMP Access UI:

    Configuration -> Device Discovery -> SNMP Access

  2. For each profile needed:

    • Security Level is always required

    • Username is always required

    • Authentication Protocol and Authentication Password are required if Security Level set to authNoPriv or authPriv

    • Privacy Protocol and Privacy Password are required if Security Level set to authPriv
