The Management Information Base
In this manual, descriptions of MIB objects are normally provided in tables with four
columns (in some instances, the third and fourth columns have been combined). This
excerpt from the table describing the System group objects in the SNMP agent’s MIB is
followed by a description of each column.
For a description of the objects in the SNMP agent’s MIB, see Section 3, MIBs
Supported by the SNMP Agent. For descriptions of the objects in each subagent’s MIB,
see Part IV, SNMP Subagents, of this manual. When objects are organized into tables,
the sections provide information about how the tables are created and maintained.

syntax.

Column 3 The third column describes the format of the value.
