| Category | Description |
|---|---|
| Network configuration | Order of operations: Network configuration should be done bottom-up, teardown should be done top-down |
| ACL | ACL key size: Rules that match on L2 fields and the complete IPv6 header cannot be specified |
| Multicast snooping | MDB records mapped to the same multicast MAC will share the same MDB record in the device. |
| Deleting such records from the bridge driver will result in the following error being printed to the kernel log: "Unable to remove port from MC DB" | |
| FRR | FRR 7.3+ installs routes using nexthop objects which are not supported by mlxsw, causing it to reject the routes. This can be fixed by the command no zebra nexthop kernel enable. The command is available in FRR 7.3.1 onwards. See this ticket for more details |
| Routing | When deleting an IP neighbour from user space, the neighbour transitions to FAILED state instead of being deleted completely. The neighbour is correctly deleted from the hardware data path and not marked with offload keyword. It can be deleted completely by issuing the deletion command again |
| Spectrum-2 | Currently raising the link at 10/40Gb/s link speed is not supported when using 200Gb/s optical cables |
| SN3800 | Split 4x25GbE not supported |
| SN3800 | Cisco Bidi module is currently not supported |
| SN3800 | Link is down after a few link toggles when using the MMA1B00-C100D 100G transceiver |
| SN3800 | InfiniBand optical cables are currently not supported |
| SN3800 | Currently raising the link at 25Gb/s / 100Gb/s link speed is not supported when using 200GbE copper cables |
| SN3800 | Connectivity to a 3rd party switch systems may not go up when using copper and optical cables |
| SN3800 | Traffic can be dropped due to high BER in link. Workaround: toggle the link |
| SN3800 | High effective BER occurs when using optical and copper cables with 100GbE link speed |
| SN3700 | At 200GbE speed, traffic drop occurs between SN3700 and IXIA |
| SN3700 | 200GbE optical cables are not supported |
| Packet Drops Monitoring | Drop monitor needs to be built as built-in (CONFIG_NET_DROP_MONITOR=y) in order to report hardware drops |
