  • Junos Traffic Vision (SRX Series Firewall and vSRX 3.0)–We now support Junos Traffic Vision (previously known as Jflow) on SRX Series Firewall. Junos Traffic Vision uses security policies and logical systems to generate flow records that capture addresses, packet counts, and byte counts. NAT44, NAT64, and NAT66 session template records include new information using J-Flow version 9 and IPFIX.

    The new elements are:

    IANA IPFIX ID Field Name Size (Bytes)
    152

    flowStartMilliseconds

    		 32
    6 tcp_flags 16
    10 input_snmp 32
    14 output_snmp 32
    95 application_id 32
    234 ingressVRFID 32
    235 egressVRFID 32

    Specify only the required template events and assign a predefined value (256 through 65535) for reuse.

    Templates also support non-NAT firewall IPv4 and IPv6.
