The following errata report has been submitted for RFC5655, "Specification of the IP Flow Information Export (IPFIX) File Format". -------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=5655&eid=4306 -------------------------------------- Type: Technical Reported by: Wayne Tackabury <wtackabury@us.ibm.com> Section: A.5 Original Text ------------- 224: 0A 47 0A B6 E5 47 0C 07 48 00|01 03 00 18 00 3E [ message checksum record ^ --> 240: 2B 37 08 CE B2 0E 30 11 32 12 4A 5F E3 AD DB 00 256:|00 0A 05 10 47 0A B6 E5 00 00 00 06 00 00 00 01 Corrected Text -------------- 224: 0A 47 0A B6 E5 47 0C 07 48 00|01 03 00 16 00 3E [ message checksum record ^ --> 240: 2B 37 08 CE B2 0E 30 11 32 12 4A 5F E3 AD DB 00 256:|00 0A 05 10 47 0A B6 E5 00 00 00 06 00 00 00 01 Notes ----- First of all, note that per erratum #2030, the offsets in this whole section are wrong, it should begin (I think) at 192. I shall use the published (incorrect) offset for illuminating this point: I believe the byte at #237 should be 0x16 and not 0x18. I suspect this checksum was copy-pasted from a prior instance in the example, where there were three pad bytes added to the data record for #259 (0x103). In this instance, there is only one pad byte at #255, hence the offset here should be two less (22 or 0x16 and not 24 or 0x18): 2 bytes set ID 2 bytes length 1 byte option data 16 bytes checksum data 1 byte pad (at #255) ...totalling 22. Thanks! Instructions: ------------- This erratum is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party (IESG) can log in to change the status and edit the report, if necessary. -------------------------------------- RFC5655 (draft-ietf-ipfix-file-05) -------------------------------------- Title : Specification of the IP Flow Information Export (IPFIX) File Format Publication Date : October 2009 Author(s) : B.
