Defining Mib Objects - Motorola BSR 2000 Reference Manual

BSR 2000 SNMP MIB Reference Guide
Some objects may occur multiple times for a single device. Objects of this type are
called tabular objects and are organized in tables. Each occurrence of a tabular object
is called an instance, and each instance also numerically encoded. For example, if you
were querying a two-port bridge's interface table, there would be two instances
(values) returned for each object in the table (one for each port), and each instance
would have a unique instance value appended to the object's OID.

Defining MIB Objects

MIB objects represent data that the
that can be modified.
A MIB object is defined and identified by the following:
OBJECT_TYPE
SYNTAX
ACCESS
1-4
RFC 1155 (Structure and Identification of Management Information for
IP-based Internets) describes the layout and encoding of exchanged data
objects. The SMI uses the ISO standard ASN.1 (Abstract Syntax Notation
One) to define a method for describing a hierarchical name space for managed
information.
RFC 1212 (Concise MIB Definitions) is an easier-to-read form used in most
standard MIBs today. It defines the private enterprise MIB.
device can retrieve or configuration information
The object's ASN.1 (Abstract Syntax Notation.1) defined
name and type.
How the data represented by this object is structured: Integer,
Octet String, Object Identifier, Null, Sequence, Sequence of,
IpAddress, NetworkAddress, Counter, Gauge, TimeTicks,
Opaque, or some other user-defined data type.
The level of management access available for this specific
object: read-only (instances of the object may be read, but not
set), read-write (instances of the object may be read or set),
write-only (instances of the object may be set but not read), or
not-accessible (instances of the object may not be read or
set). Note that this does not designate the level of access
provided by the community name you used to contact the
device, but the maximum level of access available for the
object by definition.
