Instance Specification

The MIB specifies the structure of managed information. A particular instance of a piece of information in a managed node (that is, the actual value of a specified variable) is specified by adding a zero to the OBJECT IDENTIFIER, thus:
If the particular information is not a column in a table (ie, it is a scalar), then the OBJECT IDENTIFER is given a suffix of zero, thus:
system.sysDescr.0
or
1.3.6.1.2.1.1.1.0
Thus to retrieve the instance information specified above, we could use:
get (system.sysDescr.0)
or
get (1.3.6.1.2.1.1.1.0)
