12.1 MANAGING DEVICE MIBS
The MIB Navigator lets you manage objects in the ESXMIM’s
Management Information Bases (MIBs). MIBs are databases of objects
used for managing the device and determining the ESXMIM’s
configuration. The commands within the MIB Navigator allow you to
view and modify a device’s objects.
The MIB Navigator views the MIB tree hierarchy as a directory.
Figure 12-2 shows the MIB tree hierarchy. Each layer is numerically
encoded, so that every branch group and leaf object in the MIB is
identified by a corresponding number, known as an Object Identifier
(OID). This allows the MIB Navigator to navigate through the MIB and
access the manageable leaf objects.
Figure 12-2 Hierarchical MIB Tree Structure
Often an ASCII name is assigned to a leaf object’s OID, making it more
readable. To identify the value for the object “ip Forwarding” you would
use the OID (/1/3/6/1/2/1/4/1), or its ASCII name (/iso/org/dod/internet/
mgmt/mib-2/ip/ipForwarding).
