Performance Modes

  • You cannot enable the trust mode on an SR-IOV virtual function assigned to a VNF. PR1593037
  • A message is provided in syslog if reboot is required for the mode modification to take effect in custom mode. PR1555465

Platform and Infrastructure

  • RPD core file is generated when the device reboots and daemon restarts. Daemon recovers and there is no service impact on routing protocol usage. PR1567043
  • On NFX350 devices and the SRX5000 line of devices with SPC3 card, the DPD Gateway failover feature is not supported. PR1564715
  • The l2cpd core files might be seen on reboot. PR1561235
  • 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
