Release Notes

Changes in CSIT-2001

  1. VPP PERFORMANCE TESTS

    • Service density 2n-skx tests: Added higher NF density tests with IPSec encencryption between DUTs.

    • AVF tests: Full test coveraged based on code changes in CSIT core layer (driver/interface awareness) and generated by suite generator (Fortville NICs only).

    • Hoststack TCP/IP tests: Major refactor of Hoststack TCP performance tests using WRK generator talking to the VPP HTTP static server plugin measuring connections per second and requests per second.

  2. TEST FRAMEWORK

    • CSIT Python3 Support: Full migration of CSIT from Python2.7 to Python3.6. This change includes library migration, PIP dependency upgrade, CSIT container images, infrastructure packages ugrade/installation.

    • CSIT PAPI Support: Finished conversion of CSIT VAT L1 keywords to PAPI L1 KWs in CSIT using VPP Python bindings (VPP PAPI). Redesign of key components of PAPI Socket Executor and PAPI history. Due to issues with PAPI performance, VAT is still used in CSIT for all VPP scale tests. See known issues below.

    • General Code Housekeeping: Ongoing RF keywords optimizations, removal of redundant RF keywords and aligning of suite/test setup/teardowns.

  3. PRESENTATION AND ANALYTICS LAYER

    • Graphs Layout Improvements: Improved performance graphs layout for better readibility and maintenance: test grouping, axis labels, descriptions, other informative decoration.

Issue Description

1

CSIT-570

Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds.

2

VPP-662

9000B packets not supported by NICs VIC1227 and VIC1387.

3

CSIT-1498

Memif tests are sporadically failing on initialization of memif connection.

4

VPP-1677

9000B ip4 nat44: VPP crash + coredump. VPP crashes very often in case that NAT44 is configured and it has to process IP4 jumbo frames (9000B).

5

CSIT-1591

All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much longer to program VPP). This needs to be addressed on the PAPI side.

VPP-1763

6

VPP-1675

IPv4 IPSEC 9000B packet tests are failing as no packet is forwarded. Reason: chained buffers are not supported.

7

CSIT-1593

IPv4 AVF 9000B packet tests are failing on 3n-skx while passing on 2n-skx.
