- RFC 1315 Frame Relay DTE MIB April 1992
-
-
- 1. The Network Management Framework
-
- The Internet-standard Network Management Framework consists of three
- components. They are:
-
- RFC 1155 which defines the SMI, the mechanisms used for describing
- and naming objects for the purpose of management. RFC 1212 defines a
- more concise description mechanism, which is wholly consistent with
- the SMI.
-
- RFC 1156 which defines MIB-I, the core set of managed objects for the
- Internet suite of protocols. RFC 1213 defines MIB-II, an evolution
- of MIB-I based on implementation experience and new operational
- requirements.
-
- RFC 1157 which defines the SNMP, the protocol used for network access
- to managed objects.
-
- The Framework permits new objects to be defined for the purpose of
- experimentation and evaluation.
-
- 2. Objects
-
- 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) [7]
- defined in the SMI. In particular, each object has a name, a syntax,
- and an encoding. The name is an object identifier, an
- administratively assigned name, which specifies an object type. 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 OBJECT
- DESCRIPTOR, to also refer to the object type.
-
- The syntax of an object type defines the abstract data structure
- corresponding to that object type. The ASN.1 language is used for
- this purpose. However, the SMI [3] purposely restricts the ASN.1
- constructs which may be used. These restrictions are explicitly made
- for simplicity.
-
- The encoding of an object type is simply how that object type is
- represented using the object type's syntax. Implicitly tied to the
- notion of an object type's syntax and encoding is how the object type
- is represented when being transmitted on the network.
-
- The SMI specifies the use of the basic encoding rules of ASN.1 [8],
- subject to the additional requirements imposed by the SNMP.

- RFC 1315 Frame Relay DTE MIB April 1992
-
-
- 2.1. Format of Definitions
-
- Section 4 contains contains the specification of all object types
- contained in this MIB module. The object types are defined using the
- conventions defined in the SMI, as amended by the extensions
- specified in [9,10].
-
- 3. Overview
-
- 3.1. Frame Relay Operational Model
-
- For the purposes of understanding this document, Frame Relay is
- viewed as a multi-access media, not as a group of point-to-point
- connections. This model proposes that Frame Relay is a single
- interface to the network (physical connection) with many destinations
- or neighbors (virtual connections). This view enables a network
- manager the ability to group all virtual connections with their
- corresponding physical connection thereby allowing simpler
- diagnostics and trouble shooting.
-
- 3.2. Textual Conventions
-
- Several new data types are introduced as a textual convention in this
- MIB document. These textual conventions enhance the readability of
- the specification and can ease comparison with other specifications
- if appropriate. It should be noted that the introduction of the
- these textual conventions has no effect on either the syntax nor the
- semantics of any managed objects. The use of these is merely an
- artifact of the explanatory method used. Objects defined in terms of
- one of these methods are always encoded by means of the rules that
- define the primitive type. Hence, no changes to the SMI or the SNMP
- are necessary to accommodate these textual conventions which are
- adopted merely for the convenience of readers and writers in pursuit
- of the elusive goal of clear, concise, and unambiguous MIB documents.
-
- The new data types are Index and DLCI. Index refers to the range
- 1..ifNumber, and is used to establish the correspondence between
- ifEntries and Frame Relay Interfaces. DLCI refers to the range
- 0..DLCINumber, and is used to refer to the valid Data Link Connection
- Indices. DLCINumber is, by definition, the largest possible DLCI
- value possible under the configured Q.922 Address Format.
-
- 3.3. Structure of MIB
-
- The MIB is composed of three groups, one defining the Data Link
- Connection Management Interface (DLCMI), one describing the Circuits,
- and a third describing errors.
-
-
-
-
- Brown, Baker & Carvalho [Page 3]
-
- RFC 1315 Frame Relay DTE MIB April 1992
-
-
- During normal operation, Frame Relay virtual circuits will be added,
- deleted and change availability. The occurrence of such changes is
- of interest to the network manager and therefore, one trap is
- defined, intended to be corollary to the SNMP "Link Up" and "Link
- Down" traps.
