Issue/Introduction

Attempting to send a test trap while configuring SNMP trap destination in VCF Operations for Networks returns the following error:

Environment

VCF Operations for Networks

Aria Operations for Networks

Cause

Sending a test trap from VCF Ops for Networks actually sends an SNMP informRequest which requires an acknowledgement unlike an SNMP trap. No acknowledgements (get-response) from the Network Management System (like SolarWinds) results in retries and eventually a timeout, resulting in a test trap failure.

Following messages are logged on the platform node(s) in /var/log/arkin/restapilayer/restapilayer.STDOUT<date>.log
