• under mgmt (2) above: mib-2 (1) and other branches. (See MIB-II below.)
under private (4) above: enterprise (1) and other branches. (See Cyclone
Enterprise MIB below.)
Beneath this level are non-standard branches that the enterprise may define.
Thus, the path to an object that is managed under MIB-II begins with the decimal string
1.3.6.1.2.1 and ends with the object identifier and instance(s), and the path to an object
that is managed under the Cyclone Enterprise MIB begins with 1.3.6.1.4.1, and ends with
the object identifier and instance(s).
24.2.2 ObjectInstances
An object in the MIB can have either only a single instance or multiple instances, as
follows:
• a scalar object has only a single instance. A reference to this instance is
designated by .0, following the object identifier.
• a tabular object has multiple instances that are related to each other. Tables in
the MIB associate these instances. References to these instances typically are
designated by .1, .2, and so forth, following the object identifier.
24.2.3 ManagementInformationBaseSystemsandInterface(MIB‐II)
The standard MIB-II (Management Information Base systems and interface) objects are
programmed into the Cyclone modules. To read this MIB, see Management Information
Base for Network Management of TCP/IP-based Internets: MIB II, RFC 1213 at
http://www.faqs.org/rfcs/rfc1213.html
.
The MIB-II standard categorizes each object as one of the types defined in Table 57.
