Definitions of Managed Objects for Parallel-printer-like Hardware Devices

RFC 1318               PARALLEL-PRINTER-LIKE-MIB              April 1992


   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.

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 Parallel-printer-like Hardware Device MIB applies to
   interface ports that might logically support the Interface
   MIB, a Transmission MIB, or the Character MIB (most likely
   the latter).  The most common example is a Centronics or
   Data Products type parallel printer port.

   The Parallel-printer-like MIB is one of a set of MIBs
   designed for complementary use.  At this writing, the set
   comprises:
