Cabletron Systems EMM-E6 Ethernet manual Chapter MIB Navigator, Managing Device MIBs

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.

13.1MANAGING 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.

Object 1.1.1

Group 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

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).
