The DX NetOps VNA Plugin for Cisco DNAC Issue Priority filter not working as expected.

Products

• Network Observability
• Virtual Network Assurance

Issue/Introduction

The DX NetOps VNA Plugin for Cisco DNAC ingests both DNAC Assurance Issues and Events․

The priority filters appears to be failing because the integration pulls unwanted events alongside targeted issues․

You only want DNAC Issues to generate alarms in DX NetOps Spectrum․​‎​‌​‍  

• ISSUE_PRIORITY_LIST

   

  Specifies the list of issue priorities that you want the plug-in to collect from DNAC, separated by a comma.

   

  Default:

   

  []

  Example:

   

  [p1,p2,p3,p4]

Environment

Virtual Network Assurance ALL Releases

Cause

• The DX NetOps VNA Plugin for Cisco DNAC ingests both DNAC Assurance Issues and Events․
• The ISSUE_PRIORITY_LIST filter will target specific Issue priorities, but that will not impact Event ingestion.

 

Resolution

VNA will query DNAC for issues 1-4 using specific endpoints.
