Introduction 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]? Yourtchenko, et al. Informational [Page 2]
RFC 7270 Cisco Information Elements June 2014 This document is intended to fill the gap in this IE range. It describes some additional IPFIX Information Elements in the range of 1-127, which is the range compatible with field types used by NetFlow version 9 in [RFC3954], as specified in the IPFIX Information Model [RFC7012]. With this, IPFIX implementations could export all the Information Elements specified in IANA [IANA-IPFIX], regardless of the range. This document follows the rules in "Guidelines for Authors and Reviewers of IP Flow Export (IPFIX) Information Elements" [RFC7013]. This document does not extend [RFC3954]. The IPFIX Protocol [RFC7011] has its own Information Model ([RFC7012] and IANA [IANA-IPFIX]), which is extensible upon application to IANA, subject to expert review by IE-DOCTORS [RFC7013]. This document extends the IPFIX Information Model. 2. Terminology IPFIX-specific terminology used in this document is defined in Section 2 of [RFC7011]. As in [RFC7011], these IPFIX-specific terms have the first letter of a word capitalized when used in this document. 3. Information Elements Overview The following Information Elements are discussed in the sections below: +----+-----------------------+-----+---------------------------+ | ID | Name | ID | Name | +----+-----------------------+-----+---------------------------+ | 34 | samplingInterval | 84 | samplerName | | 35 | samplingAlgorithm | 87 | flagsAndSamplerId | | 38 | engineType | 89 | forwardingStatus | | 39 | engineId | 92 | srcTrafficIndex | | 43 | ipv4RouterSc | 93 | dstTrafficIndex | | 48 | samplerId | 100 | className | | 49 | samplerMode | 102 | layer2packetSectionOffset | | 50 | samplerRandomInterval | 103 | layer2packetSectionSize | | 51 | classId | 104 | layer2packetSectionData | +----+-----------------------+-----+---------------------------+ Table 1 Yourtchenko, et al.
