Definitions of Managed Objects for Network Address Translators (NATs)
Draft of message to be sent after approval:
From: The IESG <firstname.lastname@example.org> To: IETF-Announce <email@example.com> Cc: RFC Editor <firstname.lastname@example.org> Subject: Protocol Action: 'Definitions of Managed Objects for Network Address Translators (NAT)' to Proposed Standard (draft-perrault-behave-natv2-mib-05.txt) The IESG has approved the following document: - 'Definitions of Managed Objects for Network Address Translators (NAT)' (draft-perrault-behave-natv2-mib-05.txt) as Proposed Standard This document has been reviewed in the IETF but is not the product of an IETF Working Group.

Technical Summary This memo defines a portion of the Management Information Base (MIB) for devices implementing the Network Address Translator (NAT) function. The new MIB module defined in this document, NATV2-MIB, is intended to replace module NAT-MIB (RFC 4008). NATV2-MIB is not backwards compatible with NAT-MIB, for reasons given in the text of this document. A companion document deprecates all objects in NAT- MIB. NATV2-MIB can be used for monitoring of NAT instances on a device capable of NAT function. Compliance levels are defined for three application scenarios: basic NAT, pooled NAT, and carrier-grade NAT (CGN). Working Group Summary For much of its life, this work existed as draft-ietf-behave-nat-mib in the BEHAVE working group. It became an AD-sponsored draft when BEHAVE was concluded. As a working group draft, it was not controversial, and much of the focus of discussion was between the authors of this draft, an IPFIX NAT management document, and a SYSLOG NAT management document, working to make sure each NAT management tool provided equivalent functionality, to the extent possible. The biggest decisions were whether to modify the v1 NAT MIB, or to replace it (they replaced it), and whether to replace the v1 NAT MIB and define the v2 NAT MIB in the same document, or in two documents (they chose two documents, at Dave Harrington's suggestion). Document Quality While the work was still draft-ietf-behave-nat-mib, Dave Thaler did a detailed chair review and provided comments, most of which were minor ("no RFC 2119 boilerplate, and it's needed", etc.) David Harrington also provided a detailed review from a MIB-doctor perspective for draft-ietf-behave-nat-mib, and continued to work closely with the authors after the work became draft-perrault-behave-natv2-mib to help them resolve issues he raised. Cisco has done an implementation of the draft-ietf-behave-nat-mib version. Personnel Spencer Dawkins is the responsible area director for this document, and is acting as document shepherd.
