Below is what documentation says ,so the wasp probe might be querying the discovery server on primary HUB to get the info
SNMP Device Self-Certification - CA Unified Infrastructure Management Probes - CA Technologies Documentation
Select an snmpcollector Instance
The discovery server locates systems that have an instance of the SNMP Data Monitoring (snmpcollector) probe. Select an snmpcollector instance before creating a vendor certification. Any vendor certification that you create is system-specific. Create a vendor certification for each snmpcollector instance you want to update.
