Displaying and Changing Configuration Settings and Statistics

The router’s management information base (MIB) determines its configuration

and state of operation. The following sections describe how to access the MIB

variables:

•“Using the Technician Interface to Access the MIB

”

•“Using the Technician Interface Scripts to Access the MIB

”

•“Using the Statistics Manager to Access the MIB

”

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. Using Technician Interface

Software explains how to connect a modem to the router to establish a remote

Technician Interface session.

The internal structure of the MIB contains the following:

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

special purpose.

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

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

• Valu es . 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 tables (objects)

named House and Car to store this information.

You assign each object a unique number (object identifier). For example, the

object identifier for House is 1 and Car is 2. You can access information about

houses by naming the object (House) or by using its object identifier (1).

You create attributes to describe each object. For example, you create house

attributes such as list price, size of lot, color, town, street, house number, garage or

no garage, number of bedrooms, total square feet, and how much you like it on a

scale of 1 to 10.
