CSIT Test Failure Clasification
All known CSIT failures grouped and listed in the following order:
- Always failing followed by sometimes failing.
- Always failing tests:
- Most common use cases followed by less common.
- Sometimes failing tests:
- Most frequently failing followed by less frequently failing.
- High frequency 50%-100%
- medium frequency 10%-50%
- low frequency 0%-10%.
- Within each sub-group: most common use cases followed by less common.
- Most frequently failing followed by less frequently failing.
CSIT Test Fixing Priorities
Test fixing work priorities defined as follows:
- (H)igh priority, most common use cases and most common test code.
- (M)edium priority, specific HW and pervasive test code issue.
- (L)ow priority, corner cases and external dependencies.
Current Failures
Deterministic Failures
In Trending
(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: 3n-snr
- ticket: 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: 1n-aws
- ticket: 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: 3n-alt, 3n-snr, 3n-snr
- ticket: 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)
- example: https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-vpp-perf-mrr-daily-master-3n-alt/155/log.html.gz#s1-s1-s1-s1-s1-t1

(M) wrong MAC address on lf_3n_icx_testbed37.yaml
- last update: 2023-02-09
- work-to-fix: easy
- rca: typo in topology yaml file
- test: tests using 100Ge2P1E810Cq on that testbed with dpdk plugin; AVF is not affected (as that has its own MAC addresses on VFs)
- testbed: 3n-icx, only the first testbed out of three in lab
- frequency: always, unless other 3n-icx testbed is reserved
- example: https://s3-logs.fd.io/vex-yul-rot-jenkins-1/csit-vpp-perf-report-iterative-2302-3n-icx/5/log.html.gz#s1-s1-s1-s5-s7-t1-k2-k5-k4

- ticket: CSIT-1898
(M) all testbeds: some vpp 9000B tests
- last update: 2023-02-09
- work-to-fix: hard
- rca: VPP code: 34839: dpdk: cleanup MTU handling. 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.

(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.
