Module aims and objectives

This module seeks to give the learner an understanding and knowledge of networking
fundamentals including the Open Systems Interconnect (OSI) seven-layer model
concepts, terminology and technologies using industry standard hardware and
software.

Minimum intended module learning outcomes

On successful completion of this module, the learner will be able to:

1. Construct a peer to peer Ethernet LAN

2. Solve Ethernet networking issues using switched LAN technology
3. Configure a Cisco router for basic network connectivity
4. Configure a Cisco switch
5. Construct and implement a network addressing scheme
6. Configure simple networks
7. Discuss basic security and wireless concepts

Rationale for inclusion of the module in the programme and its contribution to the
overall MIPLOs

Networking is fundamental to all modern communication in computing science.

Without it there is no internet, no Web, and no ability to develop systems that
communicate with each other. Knowledge of these areas is essential to anyone who
wants to work in the IT industry.

Appendix 1 of the programme document maps MIPLOs to the modules through which
they are delivered.

Information provided to learners about the module

Learners receive a programme handbook to include module descriptor, module
learning outcomes (MIMLO), class plan, assignment briefs, assessment strategy, and
reading materials.

Module content, organisation and structure

Review of Network Fundamentals
• TCP/IP and OSI networking models,
• Data link layer fundamentals,
• Ethernet LANs,
• WAN fundamentals,
• Fundamentals of IP, TCP and UDP

Cisco Devices
• Operating & basic configuration of Cisco Routers and switches

LAN Switching
• Understanding routing and switching
• LAN switch basics
• VLANs and Trunking
• LAN cabling & topologies

TCP/IP

67
WAN
• Remote Access technologies: PSTN, modems, ISDN, DSL, cable modems

Module teaching and learning (including formative assessment) strategy

Assessment has two components. Fifty percent of the assessment is based on
continuous assessment during module delivery. The other 50% is based on learners
taking the 640-822 Interconnecting Cisco Networking Devices Part 1 (ICND1)
examination which is held in a test centre recognised by Cisco. This exam is associated
with the Cisco Certified Entry Network Technician certification and a tangible first step
in achieving the Cisco Certified Network Associate certification.

Timetabling, learner effort and credit

The module is timetabled as one 1.5-hour lecture per week and one 1.5-hour
practical session per week.

The number of 5 ECTS credits assigned to this module is our assessment of the
amount of learner effort required. Continuous assessment spreads the learner
effort to focus on small steps and helps to ensure learner engagement over the
course of the module.

There are 36 contact hours made up of 12 lectures and 12 practical sessions

delivered over 12 weeks with both taking place in a classroom. The learner will need
50 hours of independent effort to further develop the skills and knowledge gained
through the contact hours. An additional 39 hours are set aside for learners to work
on class tests that must be completed for the module.

The team believes that 125 hours of learner effort are required by learners to
achieve the MIMLOs and justify the award of 5 ECTS credits at this stage of the
programme.

Work-based learning and practice-placement

There is no work based learning or practice placement involved in the module.

E-learning
The college VLE is used to disseminate notes, advice, and online resources to support
the learners. The learners are also given access to Lynda.com as a resource for
reference.

68
Module physical resource requirements
Requirements are for a classroom for 60 learners equipped with a projector. A
computer lab with Boson lab simulator installed.

Specifications for module staffing requirements

For each instance of the module, one lecturer qualified to at least Bachelor of Science
(Honours) in Computer Science or equivalent, and with a Certificate in Training and
Education (30 ECTS at level 9 on the NFQ) or equivalent.. Industry experience would
be a benefit but is not a requirement.

Learners also benefit from the support of the programme director, programme
administrator, learner representative and the Student Union and Counselling Service.

Module Assessment Strategy

The assignments constitute the overall grade achieved, and are based on each
individual learner’s work. The continuous assessments provide for ongoing feedback
to the learner and relates to the module curriculum.

Topology
The topology of the lab is as follows:

Scenario
The ISP_router and Web_server devices are pre-configured. Your task is to
configure the Router1, Switch1, Switch2, PC1 and PC2 to achieve the below
objectives.

Objectives
Router
1. Configure the Serial0/0 interface of Router1 with the following IP address
and subnet mask: a. IP: 100.1.1.10, mask: 255.255.255.0
2. Configure the FastEthernet0/0 interface of Router1 with the following IP
address and subnet mask:
a. IP: 192.168.100.1, mask: 255.255.255.0
3. Enable RIP version 2 on the router and enable it on the 100.1.1.0 network.
4. Set the enable secret on the router to ‘cisco’.
5. Set up source static NAT on Router1, with Serial0/0 as the outside interface,
FastEthernet0/0 as the inside interface, to translate packets leaving the

75
 router to use the IP address of the outside interface as their source IP.
Switches
1. On Switch1 and Switch2, create vlan 200 with the name ‘Office’
2. On both switches configure the ports FastEthernet0/1-11 as access ports in
vlan 200.
3. On both switches configure port FastEthernet0/12 as a trunk port.
PCs
1. Configure PC1 with the following IP address, subnet mask and gateway:
a. IP: 192.168.100.101, mask: 255.255.255.0, gateway 192.168.100.1
2. Configure PC2 with the following IP address, subnet mask and gateway:
