Using the Technician Interface to Access the MIB

The Technician Interface is an out-of-band router management and

troubleshooting tool. When the Site Manager connection to the router is

unavailable, you can use the Technician Interface as a remote management tool to

manage the router and troubleshoot the problem. The Using the Technician

Interface guide explains how to connect a modem to the router to establish a

remote Technician Interface session.

The internal structure of the MIB contains

• Objects. An object is a collection of MIB objects that store data to serve a

specialized purpose.

• Attributes. An attribute is a variable (parameter).

• Instances. An instance is a physical manifestation of an attribute.

• Values. A value is the data stored in a location indexed by an object, an

attribute associated with that object, and an instance of that attribute.

Suppose you are shopping for a house and a car, and you want to create databases

of information about houses and cars on a computer. You create objects (tables)

named “House” and “Car” to store this information. You assign each object a

unique number called an object identiﬁer. For example, the object identiﬁer for

House is 1 and Car is 2. Now you can access information by naming the object or

by using its object identiﬁer.

You create attributes to describe houses—attributes such as list price, size of lot,

type of house, color, town, street, house number, garage or no garage, number of

bedrooms, number of bathrooms, and how much you like it on a scale of 1 to 10.

You assign each attribute a unique number called an attribute identiﬁer. For

example, you use 1 for list price, 2 for size of lot, 3 for type of house, etc. To

access the size of lot, you can specify the object by name (“House”) or by

identiﬁer (“1”), and the attribute by name (“SizeOfLot”) or number (“2”) in the

format “House.SizeOfLot” or “1.2.” Now you can list the attributes of House by

entering

list House.

Example

list House

ListPrice = 1

SizeOfLot = 2

TypeOfHouse = 3

Color = 4
