Issue/Introduction

Sudden missing data, to include all historical data for SilverPeak tunnels discovered through VNA

Cause

Lines of communication from VNA to SilverPeak were mistakenly allowed to remain open which caused SilverPeak to force them shut.  This generated a 401 Unauthorized error the next time VNA tried to use them.  When VNA received the 401 error a removal of the tunnels was triggered which was the root cause behind the vanishing data.

Environment

Release : 20.2

Component : Virtual Network Assurance For CA Performance Management

Resolution

Functionality to prevent dropping tunnels completely when communication is denied (401 errors) introduced in defect DE487458 slated for release in NetOps 20.2.8.
