Hi, 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. This document defines Management Information Base (MIB) module for use with network management protocols in TCP/IP-based internets. This document proposes an extension to the Interfaces Group MIB with a set of common objects for managing multi-pair bonded Digital Subscriber Line (xDSL) interfaces, defined in ITU-T recommendations G.998.1, G.998.2 and G.998.3. The MIB modules specific to each bonding technology are defined in GBOND-ATM-MIB, GBOND-ETH-MIB and GBOND-TDIM-MIB respectively. The security considerations of this document include a number of warnings and potential threats and suggest the deployment of SNMPv3 as a mitigation. I believe this is sufficient. -derek -- Derek Atkins 617-623-3745 derek at ihtfp.com www.ihtfp.com Computer and Internet Security Consultant
