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
• You will need a diagramming application such as draw.io or Visio to complete Part 1.
• You can reference the following uCertify labs for help in building the switch
configurations: Modules 5, 6, 7, 8, 9, and 10.
• Note: access to physical or emulated Cisco devices is not required to complete this
project. However, if you want to test, practice, or otherwise tinker you can get Cisco
Packet Tracer (https://skillsforall.com/course/getting-started-cisco-packet-tracer) or
GNS3 (https://www.gns3.com/)
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 S1 and S2.
• 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:
2.1 Cable the network
Version 1.0
• Connect PC-A to S1 on Ethernet Interface 6
• Connect S1 to S2 on Ethernet Interfaces 1
• Connect PC-B to S2 on Ethernet Interface 11
• Connect PC-C to S2 on Ethernet Interface 18
2.2. Configure the basic switch functions
Configure the basic functions in both S1 and S2 as follows:
• Set the enable secret to “class”
• Set the line con 0 password to “cisco”
• Set the line vty 0 15 password to “cisco”
• Set the MOTD to “Unauthorized access is strictly prohibited.”
• Set logging to synchronous
2.3 Configure the computers
Configure the three computers as follows:
Name IP Address Subnet Gateway
PC-A 192.168.10.3 255.255.255.0 192.168.10.1
PC-B 192.168.10.4 255.255.255.0 192.168.10.1
PC-C 192.168.20.3 255.255.255.0 192.168.20.1
2.4 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
3.1 You need to define three VLANs in both S1 and S2 as follows:
• VLAN 10 Students
• VLAN 20 Faculty
• VLAN 99 Management
3.2 Then, define the following interfaces for the VLANs as:
Device Interfaces VLAN / IP Address
S1 6, 12 – 20, 22-23 VLAN 10
S1 11,21 VLAN 20
S1 VLAN 99 192.168.1.11 255.255.255.0
S2 11 VLAN 10
S2 18 VLAN 20
S2 VLAN 99 192.168.1.12 255.255.255.0
Version 1.0
Part 4: Implement VLAN Trunking
4.1 Implement VLAN trunking on the switches as follows:
• Manually set interface 1 on S1 and S2 to trunk (do not use mode dynamic desirable)
4.2 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.
