VoIP Availability Manager’s built-in trap receiver collects SNMP trap messages from two sources:
Managed network devices through the SNMP Trap Adapter configured as a trap exploder
Traps received by the built-in trap receiver are used by the enablement packs for internal processing. Configuring the deployment to distribute these traps is described in this chapter.
VoIP Performance Manager
The built-in trap receiver forwards these traps to the VoIP Performance Manager Integration Pack for processing. Configuring the deployment to distribute these traps is described in the VMware Smart Assurance VoIP Management Suite Overview and Integration Guide.
For either source, the built-in trap receiver receives SNMPv1 and v2c traps and forwards them to the appropriate enablement pack. The enablement pack, in turn, parses the traps for status updates and applies the updates to the appropriate attributes of the appropriate objects in the VoIP Availability Manager modeled topology.
By default, the built-in trap receiver is disabled, and should be enabled only when the Avaya Enablement Pack, Nortel Enablement Pack, or VoIP Performance Manager Integration Pack is installed:
The Avaya Enablement Pack uses received Avaya (Avaya-device-issued) VoIP traps to update attributes of Avaya objects in the modeled topology.
The Nortel Enablement Pack uses received Nortel (Nortel-device-issued) VoIP traps to update attributes of Nortel objects in the modeled topology
The VoIP Performance Manager Integration Pack uses received VoIP Performance Manager traps to update performance-related attributes of certain Avaya and Cisco objects in the modeled topology.
The built-in trap receiver is enabled by uncommenting the “TrapPort = 9001” parameter line in the BASEDIR/smarts/conf/voip/voip.conf file in the VoIP Management Suite installation area.
