Description
Objective:
In this lab we will be learning about how to configure switches in a Cisco environment and will be
creating a network with 5 devices: 3 PCs, a switch, and a router. This configuration can be referred to
as a Local Area Network (LAN).
The configuration includes 3 computers, connected to a switch
(similar to the network configuration used in Lab 2). In this configuration a router has been added
and will serve to manage the network using Layer 3 (IP addressing) and will be connected to the
switch Access Layer (Hierarchical Design Model) to which we will be connecting the computers. In
this document you will find the representative diagrams and IP tables we will use to create a LAN.
Before you physically create this LAN in the lab, you are to model it in CISCO Packet Tracer like you
did in Lab 2. Ensure you take screen shots of the completed model, as well as upload the Packet
Tracer file.
A teaching assistant will be available to assist you during the lab.
Credit for this assignment will require:
1) Packet Tracer File: CNT4703C-Lab3-[full-name-of-student]
2) Screenshots of Packet Tracer Model
a. Network Topology (Logical)
b. Successful Ping from PC-to-PC
c. Successful Pint from Router to PC
3) Photos of Router/Switch/PC Configuration (if ONLINE, then within Packet Tracer).
a. Router Command Results
i. Show version
ii. Show run
iii. Show ip int brief
4) Answers to LAB 3 Questions (below)
LAB 3 Questions:
1) What Layer of the OSI Model does IP addressing take place?
2) What does DHCP stand for and how is DHCP different from static addressing?
3) What is the command to enter privileged mode on a CISCO router or switch?
4) What command or set of commands did you use to configure the interfaces on the Router and
Switch?
5) Convert the subnet mask 255.255.255.0 to binary. a. How many hosts can be addressed in this
subnet?

Step 1: Enter Privilege Mode
[host]>
[host]>enable
Step 2: Display current configuration and switch information
[host]# show version
# show run
Step 3: Create/Configure hostname
[host]#Configure Terminal
[host](config)#hostname LAN-Switch
[host](config)#
Step 4: Enter configuration terminal / select interface to configure
[host]#config t
[host](config)#
#interface fa[0/?] *type the number of the interface you want to configure or
#int range fa[0/?-?] *type the range of interfaces you want to configure
[host](config-if)#
# switchport [mode] [type] (if configuring for Access Layer | type access)
Step 5: Write/Save Configuration changes
[host]#
#write memory
