Remote Network Monitoring MIB Protocol Identifiers
Alternative Format: Original Text Document
RFC 2074 RMON Protocol Identifiers January 1997
1. Introduction
This memo defines an experimental portion of the Management
Information Base (MIB) for use with network management protocols in
the Internet community. In particular, it describes the algorithms
required to identify different protocol encapsulations managed with
the Remote Network Monitoring MIB Version 2 [RMON2]. Although related
to the original Remote Network Monitoring MIB [RFC 1757], this
document refers only to objects found in the RMON-2 MIB.
2. The SNMP Network Management Framework
The SNMP Network Management Framework presently consists of three
major components. They are:
o the SMI, described in RFC 1902 [RFC 1902], - the mechanisms used for
describing and naming objects for the purpose of management.
o the MIB-II, STD 17, RFC 1213 [RFC 1213], - the core set of managed
objects for the Internet suite of protocols.
o the protocol, STD 15, RFC 1157 [RFC 1157] and/or RFC 1905 [RFC 1905],
- the protocol for accessing managed information.
Textual conventions are defined in RFC 1903 [RFC 1903], and
conformance statements are defined in RFC 1904 [RFC 1904].
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2.1. Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
defined in the SMI. In particular, each object type is named by an
OBJECT IDENTIFIER, an administratively assigned name. The object
type together with an object instance serves to uniquely identify a
specific instantiation of the object. For human convenience, we
often use a textual string, termed the descriptor, to refer to the
object type.
3. Overview
The RMON-2 MIB [RMON2] uses hierarchically formatted OCTET STRINGs to
globally identify individual protocol encapsulations in the
protocolDirTable.
