=== In Trending ===
==== (M) 2n-zn2: All 4c RDMA tests are failing ====
* last update: before 2023-02-22 * work-to-fix: medium? * rca: VPP change 38242 causes a crash, stack trace looks the same (if it exists), does not happen with debug VPP build. More specifics not known yet. * test: only on RDMA, only on 2n-zn2 (not on 2n-clx), higher core count is affected more * frequency: 4c almost always, 2c sometimes, 1c rarely. * testbed: 2n-zn2 * example: [https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-vpp-perf-mrr-daily-master-2n-zn2/683/log.html.gz#s1-s1-s1-s2-s1-t2 2n-zn2] * ticket: [https://jira.fd.io/browse/VPP-2070 VPP-2070]
==== (M) 3n-snr: All hwasync wireguard tests failing when trying to verify device ====
* last update: before 2023-01-31 * work-to-fix: hard * rca: Missing QAT driver. Symptom: Failed to bind PCI device 0000:f4:00.0 to c4xxx on host 10.30.51.93 * test: hwasync wireguard * frequency: always * testbed: 3n-snr * example: [https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-vpp-perf-mrr-daily-master-3n-snr/95/log.html.gz#s1-s1-s1-s3-s1 3n-snr] * ticket: [https://jira.fd.io/browse/CSIT-1883 CSIT-1883]
==== (M) 1n-aws: TRex mlrsearch fails to find NDR & PDR due to AWS rate limiting (5min total test duration) ====
* last update: 2023-02-09 * work-to-fix: hard * rca: * test: ip4scale2m * frequency: always * testbed: 1n-aws * example: [https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-trex-perf-ndrpdr-weekly-master-1n-aws/18/log.html.gz#s1-s1-s1-s1-s2-t1 1n-aws] * ticket: [https://jira.fd.io/browse/CSIT-1876 CSIT-1876] * note: The root cause can be shared environment in aws cloud. We may need to use a smaller scale there.
==== (M) 3n-alt, 3n-snr: testpmd no traffic forwarded ====
* last update: 2023-02-09 * work-to-fix: medium * rca: DUT-DUT link takes too long to come up on some testbeds. This happens *after* a test case with a DPDK app (not VPP even when using dpdk plugin), although multiple subsequent tests (even with VPP) may be affected. The real cause is probably in NIC firmware or driver, but CSIT can be better at detecting port status as a workaround. * test: testpmd (also l3fwd but hidden by CSIT-1896) * frequency: always (almost) * testbed: 3n-alt, 3n-snr * example: [https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-dpdk-perf-mrr-weekly-master-3n-alt/42/log.html.gz#s1-s1-s1-s1-t1 3n-alt], [https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-dpdk-perf-report-iterative-2210-3n-snr/6/log.html.gz#s1-s1-s1-s1-t1 3n-snr], [https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-dpdk-perf-report-iterative-2210-3n-snr/14/log.html.gz#s1-s1-s1-s1-t1 3n-snr] * ticket: [https://jira.fd.io/browse/CSIT-1848 CSIT-1848]
==== (M) 3n-alt: Tests failing until 40Ge Interface comes up ====
* last update: 2023-02-09 * work-to-fix: medium * rca: DUT-DUT link takes too long to come up due to CSIT-1848. * test: first tests in order * frequency: always (almost, depends on run order) * testbed: 3n-alt (3n-snr link does not take that long) * ticket: [https://jira.fd.io/browse/CSIT-1890 CSIT-1890]
==== (L) 3n-icx: negative ipackets on TB38 AVF 4c l2patch ====
* last update: 2023-02-22 * work-to-fix: * rca: * test: TB38 AVF 4c l2patch e810cq * frequency: always * testbed: 3n-icx (only TB38, never TB37) * ticket: [https://jira.fd.io/browse/CSIT-1901 CSIT-1901]

CSIT needs to rework how it sets MTU / max frame rate (CSIT-1797). Some tests will continue failing due to missing support on VPP side, we will open specific Jira tickets for those. * test: see sub-items * frequency: always * testbed: all * examples: see sub-items * ticket: [https://jira.fd.io/browse/CSIT-1809 CSIT-1809] * gerrit: https://gerrit.fd.io/r/c/csit/+/37824

==== (M) 2n-clx, 2n-icx, 2n-zn2: DPDK testpmd 9000b tests on xxv710 nic are failing with no traffic ====
* last update: 2023-02-09 * work-to-fix: medium * rca: The DPDK app only attempts to set MTU once, but if interface is down (CSIT-1848) it fails. As a workaround, MTU could be set on Linux interface before starting the DPDK app. * test: DPDK testpmd 9000b * frequency: always * testbed: 2n-clx, 2n-icx, 2n-zn2 * example: [https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-dpdk-perf-report-iterative-2210-2n-clx/1/log.html.gz#s1-s1-s1-s3-t6 2n-clx], [https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-dpdk-perf-report-iterative-2210-2n-icx/3/log.html.gz#s1-s1-s1-s1-t6 2n-icx] * ticket: [https://jira.fd.io/browse/CSIT-1870 CSIT-1870] * note: Vratko will fix, either in general workaround for CSIT-1848 or in a separate change.
