ISO Namespace Tree

Every managed object, whether a device or the characteristics of a device, has a name, a syntax, and an encoding. The name, an object identifier (OID), uniquely identifies the object. The OID is written as a sequence of integers separated by periods. For example, the sequence 1.3.6.1.2.1.1.1.0 specifies the system description within the system group of the management subtree. The OID scheme was created partly by the ISO organization. The ISO organization gives its name to the rooted tree diagrams used to represent OID values. An ISO diagram of the overall System Management Agent is shown in Figure 1–3.

The OID for SMA is 1.3.6.1.4.1.42.2.2.4

This OID corresponds to the data:

iso.org.dod.internet.private.enterprises.sun.products.management.sma
