Abstract

Section 4 of [RFC7012] defines the IPFIX Information Elements (IEs) in the range of 1-127 to be compatible with the NetFlow version 9 fields, as specified in "Cisco Systems NetFlow Services Export Version 9" [RFC3954]. As [RFC3954] was published in 2004, it does not contain all NetFlow version 9 field types in the range of 1-127. The question was asked whether IPFIX Devices should exclusively report the IANA IPFIX IEs [IANA-IPFIX]. In other words, when upgrading from a NetFlow Metering Process to an IPFIX Metering Process, should the IPFIX Devices stop reporting IEs specific to NetFlow version 9 that were not registered in IANA [IANA-IPFIX]?
