SNMP E

NVIRONMENT

C-2

Here is a portion of the EZ Stack 10 MIB:
The MIB itself has a hierarchical structure, defining objects in a tree-like structure. Using this model, the entire
world can be defined from a single origin.
Objects
Real objects in the world of network management are variables that contain values. Data types may be numbers,
character strings or structures. New data types may be created by renamin g existing data types, limiting the range of
values or structuring them using pre-defined methods. The SNMP MIB uses only a small portion of the data types
and structuring methods defined in ASN.1. See IETF documents RFC 1212 and 1213 for more information.

table.index notation

Objects are organized into tables. Each table represents a group of objects that may have multiple instances; for
example, the hrDeviceEntry table in the HR MIB contains values for device index, type, description, ID, status,
and errors. Each object has a set of values representing its operating sta tus. While the “dotted” notation for the
hrDeviceEntry table is 1.2.6.1.36.2.1, the notation for the hrDeviceIndex field is 1.2.6.1.36.2.1.1. Multiple
instances in a table are identified by an index number.
