SNMP MIB M

10. The MIB database contains both simple variables and tables.
For example, the ifEntry uses a single integer to identify each
port (i.e., interface) on a network device. When you expand a
table by double-clicking on the associated node, the Input
Index dialog box will open to query for the required table
index. You can change the table index for the current
variable (provided it is a table) using the Index button.
Much of the object data stored
in the MIBs is organized in
multi-level tables that are
accessed via segmented index
pointers. The Input Index
dialog box allows you to
display the complete index
string either as raw data, or to
display individual index
segments one at a time. Raw
data is generally displayed as a
string of integers or ASCII
text, and is not easy to
interpret for table indexes.
Segmented index entries are
displayed according to the exact data type used for each individual segment, and is generally easier to work
with. The example here shows the segmented index values for a database entry that is accessed with a two-level
pointer.
