2.2.4. Known Issues¶
Here is the list of known issues in CSIT rls1704 for VPP performance tests:
| # | Issue | Jira ID | Description |
| 1 | NDR discovery test failures 1518B frame size for ip4scale200k, ip4scale2m scale IPv4 routed- forwarding tests. ip4scale20k tests are fine. | VPP-663 | VPP reporting errors: dpdk-input Rx ip checksum errors. Observed frequency: all test runs. |
| 2 | Sporadic VAT API timeouts during ip6scale2m scale IPv6 routed-forwarding tests when volume adding IPv6 routes - 2M in this case. ip6scale200k works. | VPP-712 | Needs fixing VPP VAT API timeouts for large volume of IPv6 routes. |
| 3 | Vic1385 and Vic1227 low performance. | VPP-664 | Low NDR performance. |
| 4 | Sporadic NDR discovery test failures on x520. | CSIT-750 | Suspected issue with HW settings (BIOS, FW) in LF infrastructure. Issue can’t be replicated outside LF. |
| 5 | VPP in 2t2c setups - large variation of discovered NDR throughput values across multiple test runs with xl710 and x710 NICs. | CSIT-568 | Suspected NIC firmware or DPDK driver issue affecting NDR throughput. Applies to XL710 and X710 NICs, x520 NICs are fine. |
| 6 | Lower than expected NDR and PDR throughput with xl710 and x710 NICs, compared to x520 NICs. | CSIT-569 | Suspected NIC firmware or DPDK driver issue affecting NDR and PDR throughput. Applies to XL710 and X710 NICs. |
