9. When you execute a Get Request (or double-click on an item
in the MIB tree) or Get Bulk Request, the value of the
selected variable(s) is retrieved from the managed device and
displayed beneath the textual description. However, note
that when the Get Next request is executed, the next variable
actually retrieved may be several nodes away, so the
ObjectID and Index entries are also displayed.
Object ID Dotted-decimal identifier for current variable, indicating its exact location in the database
structure.
Type Refers to the way the data can be accessed. This item is only meaningful for real variab les.
Acceptable values include “Read Only,” “Read/Write,” or “No Acc ess.” Note that a Read-Only
object does not support the “set” operation.
Status Can be MANDATOR Y, OPTIONAL or DEPRECATED. In general, a mandatory object must
be implemented, an optional object may be omitted, and a depreciated object may be taken out of
a definition. However, according to grouping conventions as defined in the standards, ob jects may
be grouped such that all of them are implemented, or omitted altogether. In such case these
objects may have the status of MANDATORY but not be implemented without violating the
rules.
Index Index to current table entry. The IP address of the target device is commonly used as an index.
Value The value of the current variable. Value type depends on the specific variable.
Range Range of the variable in (x, y) format.
Size Size of the string data in number of bytes.
Description Text that briefly de scribes the use of the corresponding variable.
