CMIT $351$ Project $1$ Description

Intro

ACME University IT wants to implement layer $2$ segmentation to control broadcast domains and

increase Local Area Network $($LAN$)$ performance.

Scenario

IT has tasked you with creating a prototype of the new LAN. You need to document the

prototype and identify what works as well as what does not work. The requirements you have

specify a maximum number of switch $(2),$ the number of virtual LANs $($VLANs$)$ as three, and

some computers for endpoint testing.

Overview

Modern switches use VLANs to improve network performance by separating large Layer $2$

broadcast domains into smaller ones. VLANs can also be used as a security measure by

controlling which hosts can communicate. In general, VLANs make it easier to design a network

to support the goals of an organization. VLAN trunks are used to span VLANs across multiple

devices. Trunks allow the traffic from multiple VLANS to travel over a single link, while

keeping the VLAN identification and segmentation intact.

Objectives

$$ Design a Local Area Network using switches and hosts $($computers$)$

$$ Create basic switch configurations necessary for switch maintenance and operation

$$ Define Virtual LANs $($VLANs$)$ to enforce segmentation

$$ Implement necessary VLAN trunking to extend a VLAN across the LAN

Tools

$$ Access to physical Cisco devices is not required to complete this project.

$$ However, you will need the Cisco Packet Tracer educational tool as this project will be

completed as a Cisco Packet Tracer Activity.

$$ You can reference the following uCertify labs for help in building the switch

configurations: Modules $5,6,7,8,9,$ and $10.$

Submission

Use the Project $1$ Template MS Word to document screenshots and descriptive answers for your

submission. Fundamentally, you need to attach$/$submit two things:

a$)$ The completed Cisco Packet Tracer activity file $($do not forget to save the PKA file once you have

completed the project activity before uploading$)$

b$)$ Screenshots and descriptive answers will go into the MS Word document $$CMIT $351$ Project $1$

Template$.$

Version $2\mathrm{.}0$

Part $1$: Design the Local Area Network

The work milestones for this part of the project are as follows:

$$ The LAN must consist of $2$ switches and $3$ computers.

$$ The two switches must be named S$1$ and S$2.$

$$ The three computers must be named PC$-$A$,$ PC$-$B$,$ and PC$-$C$.$

Part $2$: Create the basic switch configurations

Your network engineering lead has approved the LAN design. Now, the work to implement the

design can begin. Your tasks are as follows:

$2\mathrm{.}1$ Cable the network

$$ Connect PC$-$A to S$1$ on Ethernet Interface $6$

$$ Connect S$1$ to S$2$ on Ethernet Interfaces $1$

$$ Connect PC$-$B to S$2$ on Ethernet Interface $11$

$$ Connect PC$-$C to S$2$ on Ethernet Interface $18$

$2\mathrm{.}2.$ Configure the basic switch functions

Configure the basic functions in both S$1$ and S$2$ as follows:

$$ Set the enable secret to $$class$$

$$ Set the line con $0$ password to $$cisco$$

$$ Set the line vty $015$ password to $$cisco$$

$$ Set the MOTD to $$Unauthorized access is strictly prohibited.$$

$$ Set logging to synchronous

$2\mathrm{.}3$ Configure the computers

Configure the three computers as follows:

Name IP Address Subnet Gateway

PC$-$A $192\mathrm{.}168\mathrm{.}10\mathrm{.}3255\mathrm{.}255\mathrm{.}255\mathrm{.}0192\mathrm{.}168\mathrm{.}10\mathrm{.}1$

PC$-$B $192\mathrm{.}168\mathrm{.}10\mathrm{.}4255\mathrm{.}255\mathrm{.}255\mathrm{.}0192\mathrm{.}168\mathrm{.}10\mathrm{.}1$

PC$-$C $192\mathrm{.}168\mathrm{.}20\mathrm{.}3255\mathrm{.}255\mathrm{.}255\mathrm{.}0192\mathrm{.}168\mathrm{.}20\mathrm{.}1$

$2\mathrm{.}4$ Test and Validate Connectivity

Use ping to test connectivity between the computers. Detail your results in your project

document, both what works and what doesn$$t work.

Part $3$: Define the VLANs

$3\mathrm{.}1$ You need to define three VLANs in both S$1$ and S$2$ as follows:

$$ VLAN $10$ Students

Version $2\mathrm{.}0$

$$ VLAN $20$ Faculty

$$ VLAN $99$ Management

$3\mathrm{.}2$ Then, define the following interfaces for the VLANs as:

Device Interfaces VLAN $/$ IP Address

S$16,1220,22-23$ VLAN $10$

S$111,21$ VLAN $20$

S$1$ VLAN $99192\mathrm{.}168\mathrm{.}1\mathrm{.}11255\mathrm{.}255\mathrm{.}255\mathrm{.}0$

S$211$ VLAN $10$

S$218$ VLAN $20$

S$2$ VLAN $99192\mathrm{.}168\mathrm{.}1\mathrm{.}12255\mathrm{.}255\mathrm{.}255\mathrm{.}0$

Part $4$: Implement VLAN Trunking

$4\mathrm{.}1$ Implement VLAN trunking on the switches as follows:

$$ Manually set interface $1$ on S$1$ and S$2$ to trunk $($do not use mode dynamic

desirable$)$

$4\mathrm{.}2$ Use ping to test connectivity between the computers and switches. Detail your

results in your project document, both what works and what doesn$$t work.
