-
- Definitions of Managed Objects for
- RS-232-like Hardware Devices
-
- Status of this Memo
-
- This document specifies an IAB standards track protocol for the
- Internet community, and requests discussion and suggestions for
- improvements. Please refer to the current edition of the "IAB
- Official Protocol Standards" for the standardization state and status
- of this protocol. Distribution of this memo is unlimited.
-
- 1. Abstract
-
- This memo defines a portion of the Management Information Base (MIB)
- for use with network management protocols in TCP/IP based internets.
- In particular, it defines objects for the management of RS-232-like
- devices.
-
- 2. 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.
-
- 3. Objects
-
- Managed objects are accessed via a virtual information store, termed
- the Management Information Base or MIB. Objects in the MIB are
-
-
-
- Character MIB Working Group [Page 1]
-
- RFC 1317 RS-232-LIKE MIB April 1992
-
-
- 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.
-
- 3.1. Format of Definitions
-
- Section 5 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].
-
- 4. Overview
-
- The RS-232-like Hardware Device MIB applies to interface ports that
- might logically support the Interface MIB, a Transmission MIB, or the
- Character MIB. The most common example is an RS-232 port with modem
- signals.
-
- The RS-232-like MIB is one of a set of MIBs designed for
- complementary use. At this writing, the set comprises:
-
- Character MIB
- PPP MIB
- RS-232-like MIB
- Parallel-printer-like MIB
-
- The RS-232-like MIB and the Parallel-printer-like MIB represent the
- physical layer, providing service to higher layers such as the
- Character MIB or PPP MIB. Further MIBs may appear above these.
-
-
-
- Character MIB Working Group [Page 2]
-
- RFC 1317 RS-232-LIKE MIB April 1992
-
-
- The following diagram shows two possible "MIB stacks", each using the
- RS-232-like MIB.
-
- .-----------------.
- .-----------------. | Standard MIB |
- | Telnet MIB | | Interface Group |
- |-----------------| |-----------------|
- | Character MIB | | PPP MIB |
- |-----------------| |-----------------|
- | RS-232-like MIB | | RS-232-like MIB |
- `-----------------' `-----------------'
-
- The intent of the model is for the physical-level MIBs to represent
- the lowest level, regardless of the higher level that may be using
- it. In turn, separate higher level MIBs represent specific
- applications, such as a terminal (the Character MIB) or a network
- connection (the PPP MIB).
-
- The RS-232-like Hardware Device MIB is mandatory for all systems that
- have such a hardware port supporting services managed through some
- other MIB, for example, the Character MIB or PPP MIB.
-
- The MIB includes multiple similar types of hardware, and as a result
- contains objects not applicable to all of those types. Such objects
- are in a separate branch of the MIB, which is required when
- applicable and otherwise absent.
-
- The RS-232-like Hardware Port MIB includes RS-232, RS-422, RS-423,
- V.35, and other asynchronous or synchronous, serial physical links
- with a similar set of control signals.
-
- The MIB contains objects that relate to physical layer connections.
- Such connections may provide interesting hardware signals (other than
- for basic data transfer), such as RNG and DCD. Hardware ports also
- have such attributes as speed and bits per character.
-
- Usefulness of error counters in this MIB depends on the presence of
- non-error character counts in higher level MIBs.
-
- The MIB comprises one base object and four tables, detailed in the
- following sections. The tables contain objects for all ports,
- asynchronous ports, and input and output control signals.
