The IESG has approved RFC2895, 'Remote Network Monitoring MIB Protocol Identifier Reference' to advance to a Draft Standard. This document is the product of the Remote Network Monitoring Working Group. The IESG contact persons are Bert Wijnen and Randy Bush Technical Summary This memo defines a notation describing protocol layers in a protocol encapsulation, specifically for use in encoding INDEX values for the protocolDirTable, found in the RMON-2 MIB (Remote Network Monitoring Management Information Base) (RFC2021). The definitions for the standard protocol directory base layer identifiers are also included. The first version of the RMON Protocol Identifiers Document (RFC2074) has been split into a standards-track Reference portion (this document), and an Informational document. The RMON Protocol Identifier Macros document (RFC2896) now contains the non-normative portion of that specification. This document obsoletes RFC 2074. Working Group Summary The WG has consensus to advance this document to Draft Standard. Protocol Quality This document has been reviewed for the IESG by Bert Wijnen The implemenation report is at http://www.ietf.org/IESG/Implementations/RFC2895-Implementation.txt
