Chapter 12: The MIB Navigator Screen

12.1MANAGING 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.

	Group 1.1	Object 1.1.1
		Object 1.1.2
Root 1	Group 1.2	Object 1.2.1
		Object 1.2.2
	Group 1.3	Object 1.3.1
		Object 1.3.2

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).
