Hi, We have been discussing and working through a number of known issues since VPP v22.02 and CSIT-2202 shipped.
Entering v22.06 rc2, so I thought it’s good time to take an overall read of status, as jira is not always an accurate reflection. Below my compilation based on CSIT-2202 report and listed jira Tickets. Appreciate if folks could review and ack/nack/update the status, and share their thoughts. Cheers, -Maciek ------------------------------------------------------------------------ List of known issues in CSIT-2202 from [CSIT-2202/vpp_performance_tests/csit_release_notes.txt] (https://s3-docs.fd.io/csit/rls2202/report/_sources/vpp_performance_tests/csit_release_notes.rst.txt): 1.
