Counts corresponding to tx/rx remain at zero for one of the flows and this affects the verified count. #244

Closed ArunPrakashThangaraj closed 4 months ago

ArunPrakashThangaraj commented 5 months ago

Describe the bug

Session traffic verified flow-count does not look complete as the tx/rx counts remain at 0.

To Reproduce

The issue is manually not reproducible whereas using the script it always recurs. Steps to reproduce have been shared via email with Chrisitian.

Steps to reproduce the behavior:

  1. Shared vial email.

Expected behavior

tx/rx count for all enabled session-traffic flows (ipv4/ipv6/ipv6pd) should get started and verified count should be 6, considering both upstream/downstream flows for each ipv4/ipv6/ipv6pd
