This website uses cookies so that we can provide you with the best user experience possible. 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. Alternatively, to see what data is contained within IPFIX – an alternative to NetFlow – see our similar post on IPFIX. Port number; Specify the UDP port to listen on. Version 5 (V5) is an enhancement that adds Border Gateway Protocol (BGP) autonomous system information and flow sequence numbers. Traffic-Flow supports the following NetFlow formats: version 1 - the first version of NetFlow data format, do not use it, unless you have to version 5 - in addition to version 1, version 5 has possibility to include BGP AS and flow sequence number information. NetFlow collectors use templates to decipher the fields that the firewall exports. Minimum IP packet length on incoming packets of the flow, Maximum IP packet length on incoming packets of the flow, Length of the IPv6 source mask in contiguous bits, Length of the IPv6 destination mask in contiguous bits, IPv6 flow label as per RFC 2460 definition, Internet Control Message Protocol (ICMP) packet type; reported as ((ICMP Type*256) + ICMP code), Internet Group Management Protocol (IGMP) packet type, When using sampled NetFlow, the rate at which packets are sampled i.e. Japanese / 日本語 The NetFlow V9 record format consists of a packet header and at least one or more template or data FlowSets. Chinese Simplified / 简体中文 The firewall selects a template based on the type of exported data: IPv4 or IPv6 traffic, with or without NAT, and with standard or enterprise-specific (PAN-OS specific) fields. As a NetFlow collector, SolarWinds NTA can receive exported NetFlow version 5 data and NetFlow version 9 data that includes all fields of the NetFlow version 5 template. As Traffic-Flow is compatible with Cisco NetFlow, it can be used … : FTP, Telnet, or equivalent, The number of contiguous bits in the source address subnet mask i.e. If not present in the template, then version 4 is assumed. NetFlow allows you to collect traffic so that it can be analyzed. Both of these protocols bundle multiple samples (Data Set in NetFlow/IPFIX and Flow Sample in sFlow) in one packet. The advantages of using an abstract network flow format, such as protobuf, is it enables summing over the protocols (eg: per ASN or per port, rather than per (ASN, router) and (port, router)). Netflow is a standardized format to export network data. Dutch / Nederlands These data FlowSets might occur later within the same export packet or in subsequent export packets. Flow data represents a single packet flow in the network with the same 5-tuple identification composed of source IP address, destination IP address, source port, destination port and protocol.
