      Remote Network Monitoring MIB Protocol Identifier Reference

Status of this Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   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.
