Introduction

Phil Smith

Learning outcome LO1/LO2On successful completion of this unit you will be able to:

LO1. Examine networking principles and their protocols.

LO2. Explain networking devices and operations.

LO3. Design efficient networked systems.

LO4. Implement and diagnose networked systems.

LO4 Topic: Networking devices

Understand installation of communication devices, allocation of addresses, local client configuration, server configuration and server installation.

You started this last time:

Implement a networked system related to the design prepared in the LO1 and LO2 assessment.

You need to spend some time on your design in Cisco packet tracer.

Note: Take a copy of the file so you can continue at home.

LO4 Topic: Networking devices

How do we configure a network switch?

Some common tasks are –

Name the switch.

Give an IP address

Add/change the password.

Show the running configuration.

Let us do some of these tasks.

LO4 Topic: Networking devices Task configure a network switch?

Name the switch.

Give an IP address

Add/change the password.

Show the running configuration.

Use your MWS design in packet tracer.

Select one of your switches.

LO4 Topic: Networking devices

When we think of connectivity in a network, the router

is probably the first device that comes to mind, but

switches play a vital role in enabling devices to

communicate. Switches can take incoming/outgoing

traffic and pass it onwards toward its final destination.

Cisco is one of the most well-known switch vendors

on the market and in this article we’re going to look at

how to configure Cisco switches.

LO4 Topic: Verification of configuration and

connectivity

Overview of connectivity verification methods.

Conduct verification with (e.g. Ping, traceroute, telnet,

SSH).

We have already run various network commands

Start a cmd window and run ping again; use

127,0,0,1 then ping another students PC (by

arrangement)

LO4 Topic: Verification of configuration and

connectivity

Task

Record and evaluate Ping results as successful/unsuccessful into a text file?

Create a bat file to execute this code –

@echo off

echo %date% %time%>ping.txt

ping 127.0.0.1 >>ping.txt

What does this do? Check for a file named “ping.txt”

LO4 Topic: maintenance schedule

Overview of connectivity verification methods.

Plan and manage a maintenance schedule.

How would you go about this task?

Task - as a group

List steps for backup and restore depending on the network and operating systems you are using and upgrades.

Discuss the significance of upgrades and security requirements (Win 10 updates)

LO4 Topic: Diagnose and resolve layer 1

problems

Document and analyse test outcomes against

expected results.

Discuss the test techniques for framing, CRC, Runts

and Giants.

What are these strange terms?

We have come across CRC before – can you

remember this?

LO4 Topic: Diagnose and resolve layer 1

problems

Discuss the test techniques for framing, CRC, Runts

and Giants.

https://www.cisco.com/en/US/docs/internetworking/tro

ubleshooting/guide/tr1904.html

Task - this is very technical but remember we are

testing layer 1 problems.

Research the terms and how to test for them.

LO4 Topic: Diagnose and resolve layer 1

problems

Task

In your packet tracer design for MWS can you ping

from a PC to another -

Investigate dropped packets, late collisions and

Input/Output errors. Use ping and packet tracer

LO4 Topic: Systems monitoring

Plan systems monitoring and future enhancement

directions.

Network monitoring is the use of a system that

constantly monitors a computer network for slow or

failing components and that notifies the network

administrator (via email, SMS or other alarms) in case

of outages or other trouble. Network monitoring is part

of network management.

LO3 & 4 Topic: Review and preparation for assessment

tutorial

Overview of learning covered in the second half of the

unit and collate the information (e.g. observation

records, test results, design specification for

assessment).

Sample activities:

Review requirements for collating output and test

results.

Consider the assessment requirements, review

progress in gathering examples and plan for

completion of the assessment.

What have we learnt in this

session?

1. Over to you.

2. Assignment will be issued probably next week.
