The most recent evolution of the NetFlow flow-record format is known as Version 9. NetFlow v9 exporters may be configured to send template records at intervals as long as 30 minutes. In short, v9 sends empty flow records, which serves as the template. The NetFlow v9 record format consists of a packet header followed by at least one or more template or data FlowSets. The NetFlow V9 record format consists of a packet header and at least one or more template or data FlowSets. This arrangement allows for flexible export. NetFlow is the technology and term used exclusively by Cisco Systems. Templates greatly enhance the flexibility of the NetFlow record format, because they allow a NetFlow collector or display application to process NetFlow data without necessarily knowing the format of the data in advance. Starting in software version 5.3, the Common Event Format (CEF) version 23 is also supported. sequence number, record count, and sysuptime. One of the key elements in the new Version 9 format is the template FlowSet. Templates are used to describe the type and length of individual fields within a NetFlow data record that match a template ID. If the specified number of seconds elapses, IPSO exports a record for the flow. The basic output of NetFlow is a flow record. A NetFlow record can contain a wide variety of information about the traffic in a given flow. The NetFlow record format consists of a packet header followed by at least one or more template or data FlowSets. NetFlow v9 Export Format. The record format is defined by a packet header, followed by at least one template FlowSet and data FlowSet. vrf vrf . Several different formats for flow records have evolved as NetFlow has matured. The NetFlow V9 record format consists of a packet header and at least one or more template or data FlowSets. NetFlow record. sequence number, record count, and sysuptime. NetFlow record. NetFlow may be generated by a router or by software that reads packet capture (pcap(3)) data and generates NetFlow v5 records. The very most recent evolution of a flow record format of the Netflow is called as the Netflow version9 format, that is a basis for the IETF standard which is the template based. A template FlowSet provides a description of the fields that will be present in future data FlowSets. RFC 3954 Cisco Systems NetFlow Services Export V9 October 2004 Export Packet An Export Packet is a packet originating at the Exporter that carries the Flow Records of this Exporter and whose destination is the NetFlow Collector. Number of records (v5 or v8) or list of templates and records (v9) The NetFlow Version 9 record format consists of a packet header followed by at least one or more template or data FlowSets. Therefore prior to AireOS 8.2 release, only few Netflow collector software (eg-Cisco Prime, Scrutinizer) were able to decode Netflow Data coming from WLCs. Number of records (v5 or v8) or list of templates and records (v9) Records. The format of the export flow records. The record format is defined by a packet header, followed by at least one template FlowSet and data FlowSet. The Version 9 flow record is template based. The basic output of NetFlow is a flow record . There are several various formats for the flow records is evolved when the Netflow becomes matured. That means that future enhancements can be accommodated without having to change the basic flow record. They are sent on a regular basis, so in reality the flow record format can change dynamically. inactive-timeout <seconds> // T he number of seconds to wait while a flow is inactive (no traffic) but has not been terminated. The most recent evolution of the NetFlow flow-record format is known as Version 9. Netflow v9 and IPfix use a template based system. The basic output of NetFlow is a flow record. bitkeks / python-netflow-v9-softflowd / netflow / ipfix.py View on Github def __init__ ( self, data ): pack = struct.unpack( "!HHH" , data[: 6 ]) self.template_id = pack[ 0 ] # range 256 to 65535 self.field_count = pack[ 1 ] # includes count of scope fields # A scope field count of N specifies that the first N Field Specifiers in # the Template . Templates are used to describe the type and length of individual fields within a NetFlow data record that match a template ID. These data FlowSets might occur later within the same export packet or in subsequent export packets. This template is required to understand thr format of the record, therefore needs to be provided when building or dissecting those. NetFlow v9 collectors, such as the System Monitor, cannot decode a data record until it has received the corresponding template. The NetFlow Version 9 record format consists of a packet header followed by at least one or more template or data FlowSets (Figure 1). Data fields that an MX or Z-Series will export via NetFlow are: . edge server, yarn node). IPFIX does not have this constraint. One of the key elements in the new NetFlow V9 format is the template FlowSet. 2.3 IPFIX IPFIX is a template-based, record-oriented, binary ex-port format. The fields exported are based on the NetFlow Version 9 Flow-Record Format. Templates provide an This means that records that are sent over the wire require a "Template" to be sent previously in a Flowset packet. srcaddr <ip_address> // The source (local . CEF is a standard format used by event collection/correlation Security Information and Event Management (SIEM) vendors. A template FlowSet provides a description of the fields that will be present in future data FlowSets. Both IPFIX and Netflow v9 define three types of records: templates, options templates, and data records. Site24x7 supports both these formats (NetFlow v5 and v9).
