T2 2019 BN202: Network Design and IOS Information for Evergreen School

This report delves into the critical roles of network hardware components, network design, and IOS modes in setting up networks, focusing on a case study for Evergreen School. It begins by outlining the project scope, network hardware requirements (Cisco router, switches, and access points), and the logical network design. The report then details the configuration of a router and a switch, including date and time setup, interface configurations, and explanations of various IOS modes such as User EXEC, Privileged EXEC, Global Configuration, configure interface, and configure sub-interface modes, supplemented with screenshots. The IOS version used is Packet Tracer 6.2. The report concludes by summarizing the key aspects of network design and IOS configuration, providing a comprehensive overview of the network setup process.

Summary
According numerous researches the network hardware components, network design and the IOS
modes play the most crucial role in setting up networks. First the report lists the project scope. Then
the equipment required for the network gets mentioned. After that the report discusses the network
design. Next the report talks about setting up date, time and the various IOS modes of the router
and the switch with screenshots. Then after providing the IOS version the report ends with
conclusions.

Introduction
The below report attempts to highlight the role of network hardware components, network
design and the IOS modes in setting up networks. The report starts by listing the scope of the
project. Then the equipment required for the network gets mentioned. After that the report
discusses the network design. Next the report talks about setting up date, time and the various IOS
modes of the router and the switch with screenshots. Then after providing the version of IOS image
the report ends with conclusions.
Scope of Project
The network of Evergreen school should be supporting network connectivity for up to 400 students
along with 40 teachers.
The two buildings of the school for primary school and high school combined are supposed to host
computers of 20 classrooms.
The network should be able to provide both wired and wireless network connectivity from both
buildings of primary school and high school.
The wireless network strength should be strong enough to support WLAN connections for wireless
devices of both students and teachers.
The students and staff of Evergreen School should have different credentials for logging into the
school network.
Network Hardware Requirements
The different networking hardware required for setting up the network are:
A Cisco generic router of 2900 series for acquiring and routing Internet service from the ISP.
Three Cisco switches of model 2960, one of which is used as a multilayer switch while the other ones
act as access layer switches.
A wireless access point for the each floor of the school buildings to serve wireless connectivity for
the supported devices of both the students and the staff.
Two RADIUS servers for authenticating the credentials of students and staff of Evergreen School for
accessing the school network.
Network Design
Logical Network Design

Figure 1: Logical Network Design of Evergreen School
The above diagram shows the logical design of the network of Evergreen School. From this diagram
it is clearly evident how the internet access is acquired by the school and routed to different network
segments. Different access privileges are set for user groups – student and staff. The user is granted
network access based on the credentials entered in the captive portal. All these user credential
validation requests are processed by the RADIUS authentication servers. There exist multiple
wireless access points on every floor of the two buildings except the ground floor to setup the
WLAN. This allows users to have wireless connectivity for their smartphones and laptops.

Router
Date and Time Setup
As can be seen from the screenshot above, the hostname of the router gets changed into the name
of the student, Carlos of Evergreen School. Then the time and date is set to 4:45 pm or 16:45 of
September 20th of 2019.
Interfaces

6NETWORK DESIGN AND IOS INFORMATION
The above screenshot shows that the serial interface Se2/0 of the ISP router and Se2/0 of Carlos
router is used by the Evergreen School to obtain Internet access. Then the network provides the
network access to the multilayer switch through the interface Fa0/0.
IOS mode 1 User EXEC
This is the primary mode when logging into the router. In work environments, this mode is normally
protected by passwords. The user needs the valid user id and password for accessing this mode.
User gets maximum of 3 chances to enter the correct password.

7NETWORK DESIGN AND IOS INFORMATION
IOS mode 2 Privileged EXEC
Privileged EXEC refers to the main exec mode. Similar to user exec mode, the mode is generally
protected by passwords in work environments. Show, clear are the commands that are usually
entered in this mode.

8NETWORK DESIGN AND IOS INFORMATION
IOS mode 3 Global Configuration
Next in the line of IOS mode sequence comes the Global configuration mode. This mode gets used
for configuring devices globally, or for entering configuration details of interfaces and the different
protocols used.

9NETWORK DESIGN AND IOS INFORMATION
IOS mode 4 configure interface
This mode gets used for configuring interface specific details. Several settings are allowed on
interface to interface basis such as serial ports or Ethernet. Configuration commands for interfaces
are used change the settings of these interfaces like enabling or disabling interfaces, setting
bandwidth, clock rates among others.

10NETWORK DESIGN AND IOS INFORMATION
IOS mode 5 configure sub-interface
If the interfaces support virtualization, the sub interface mode gets used for configuring this virtual
interface. In the sub-interface configuration mode one can configure several virtual interfaces called
sub interface on one physical interface.

11NETWORK DESIGN AND IOS INFORMATION
IOS mode 6 Router Setup
After booting, therouter tries locating running configurations if any. When such a configuration is
found, the router loads it. If not, the router initiates setup mode.
