CHAPTER 13

MIB NAVIGATOR

This chapter describes the procedures required to access the MIB

Navigator residing on the EMM-E6. The MIB Navigator Command Set is

described and examples of each command are provided.

13.1 MANAGING DEVICE MIBs

The MIB Navigator allows access to a command set from which you can

conﬁgure and manage your device. The MIB Navigator enables you to

manage objects in the device MIBs (Management Information Bases).

MIBs are databases of objects used for managing the device and

determining your EMME’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

13-1). 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 13-1. 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).
