Objects
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.

The MIB-II standard categorizes each object as one of the types defined in Table 3:

For additional reporting and control, the Canopy Releases 3.2.5 and later provide the Canopy
Enterprise MIB, which extends the objects for any NMS that uses SNMP interaction. This MIB
comprises five text files that are formatted in standard ASN.1 (Abstract Syntax Notation One)
language.
