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


  • When you run a show interface command on NFX150 devices to check the interface details, the system does not check whether the interface name provided is valid or invalid. The system does not generate an error message if the interface name is invalid. PR1306191

  • On NFX350 devices, when you run the show interfaces queue command on the gr-1/0/0 interface, the Egress queue statistics are not applicable to this interface. error message appears. Due to this error, interface queue statistics might not be available for the gr-1/0/0 interface. PR1530855

Platform and Infrastructure

  • On NFX150 devices, when J-Flow v5 is configured and the J-Flow v5 server is reachable through an IPsec tunnel, and the MTU size of this IPsec tunnel is configured as 1500, the J-Flow packets are not generated on NFX Series devices. As a workaround, use J-Flow v9 or IPFIX version, instead of J-Flow v5, to enable the J-Flow functionality on NFX Series devices. PR1539964

Virtual Network Functions (VNFs)

  • On NFX150 devices, before reusing a VF to Layer 3 data plane interfaces (for example, ge-1/0/3), which was earlier allocated to a VNF, you must restart the system. PR1512331
