I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. From the abstract: This document updates RFC 5066. It amends that specification by informing the internet community about the transition of the EFM-CU- MIB module from the concluded IETF Ethernet Interfaces and Hub MIB Working Group to the Institute of Electrical and Electronics Engineers (IEEE) 802.3 working group. The security considerations section appears to be identical to RFC5066. Given the stated purpose of the document, this seems appropriate. --Scott
