Specifies the format of the export flow records. • Export packets can be composed of both template and data FlowSets, • Template and data FlowSets can be interleaved, • The template ID in the template record maps to the FlowSet ID in a corresponding data FlowSet, • The layout of the data in the data record maps to the fields formats defined in the template record. • Data record-A data record provides information about an IP flow that exists on the device that produced an export packet. • Templates periodically expire if they are not refreshed. This field gives the relevant portion of the NetFlow process to which the options record refers. The Collector should maintain a similar list: . NetFlow Version 9 Packet Header Field Descriptions, The version of NetFlow records exported in this packet; for Version 9, this value is 0x0009, Number of FlowSet records (both template and data) contained within this packet, Time in milliseconds since this device was first booted, Seconds since 0000 Coordinated Universal Time (UTC) 1970, Incremental sequence counter of all export packets sent by this export device; this value is cumulative, and it can be used to identify whether any export packets have been missed, Note: This is a change from the NetFlow Version 5 and Version 8 headers, where this number represented "total flows.". Currently, the template record that describes flow fields has a FlowSet ID of zero and the template record that describes option fields (described below) has a FlowSet ID of 1. 韓国語 / 한국어 A template record always has a FlowSet ID in the range of 0-255. ポルトガル語 / ポルトガル / Português/Portugal When interpreting the NetFlow Version 9 data FlowSet format, note that the fields cannot be parsed without a corresponding template ID. If the specified number of seconds elapses, IPSO exports a record for the flow. If you configure three collectors, each record is sent three times. Cisco supplied values are consistent across all platforms that support NetFlow Version 9. Route distinguisher ensures that the same address can be used in several different MPLS VPNs and that it is possible for BGP to carry several â¦ • Third-party business partners who produce applications that provide collector or display services for NetFlow will not be required to recompile their applications each time a new NetFlow feature is added; instead, they may be able to use an external data file that documents the known template formats, • New features can be added to NetFlow more quickly, without breaking current implementations, • NetFlow is "future-proofed" against new or developing protocols, because the Version 9 format can be adapted to provide support for them. : a value of 100 indicates that one of every 100 packets is sampled, The type of algorithm used for sampled NetFlow: 0x01 Deterministic Sampling ,0x02 Random Sampling, Timeout value (in seconds) for active flow entries in the NetFlow cache, Timeout value (in seconds) for inactive flow entries in the NetFlow cache, Type of flow switching engine: RP = 0, VIP/Linecard = 1, Counter with length N x 8 bits for bytes for the number of bytes exported by the Observation Domain, Counter with length N x 8 bits for bytes for the number of packets exported by the Observation Domain, Counter with length N x 8 bits for bytes for the number of flows exported by the Observation Domain, IPv4 source address prefix (specific for Catalyst architecture), IPv4 destination address prefix (specific for Catalyst architecture), MPLS Top Label Type: 0x00 UNKNOWN 0x01 TE-MIDPT 0x02 ATOM 0x03 VPN 0x04 BGP 0x05 LDP, Forwarding Equivalent Class corresponding to the MPLS Top Label, The type of algorithm used for sampling data: 0x02 random sampling.
