High Availability

  • On an NFX350 chassis cluster, when FPC0 (when node0 is primary) or FPC7 (when node1 is primary) is restarted by either using the request chassis fpc slot slot restart node local command or due to dcpfe core files on the primary, it restarts FPC1 or FPC8. This might break the preexisting TCP sessions and fail to restart the TCP sessions. The TCP sessions might require a manual restart. PR1557607


  • L3 dataplane interfaces are not appearing when flex mode is enabled on NFX350-S3 devices. As a workaround, enable only compute, hyrbrid, or throughput mode on NFX350-S3 devices.PR1599643

Platform and Infrastructure

  • Jumbo frames are not supported through OVS on an NFX250 device. PR1420630

Virtual Network Functions (VNFs)

  • Coredump might happen in the first boot of an NFX250 device that is in compute mode and configure VNF with more than 2G memory. PR1589655
