Release Notes

Changes in CSIT-2009

  1. VPP PERFORMANCE TESTS

    • CSIT test environment is versioned, see Environment Versioning.

    • To identify performance changes due to VPP code changes from v20.01.0 to v20.05.0, both have been tested in CSIT environment ver. 4 and compared against each other. All substantial progressions has been marked up with RCA analysis. See Current vs Previous Release and Known Issues.

  2. TEST FRAMEWORK

    • CSIT PAPI support: 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.

Known Issues

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

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).

4

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

5

VPP-1675

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

6

CSIT-1593

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

7

CSIT-1679

2n-clx VPP ip4 tests with xxv710 and avf driver are sporadically failing.
