Network Design and Configuration Analysis

This assignment delves into the analysis of a pre-designed network, focusing on interface configuration and troubleshooting techniques. It begins by outlining the process of identifying interfaces using the 'show interfaces' command and addressing issues encountered during initial testing involving ping responses. The analysis culminates in evaluating the network's potential applications in business settings, such as creating secure guest networks, grouping employees based on data usage, and restricting access to sensitive information.

Directly connected devices to router
There are no directly connected devices with the router.
The connected devices to the router can be shown with the help of “show cdp neighbors” command.
The output will be represented in table format as below:

4. Troubleshooting steps
The problems that were faced during configuration of the devices being used for the network design are listed
as below:
Identification of the interface
Problem - The determination of the interfaces of the different devices being used was a major activity for
appropriate configurations. It was a bit difficult task to identify the appropriate interfaces being used by the
different devices.
Solution - However, this problem was resolved with the help of “show interfaces” command that helped to
check the present interfaces in a particular device. With the help of this command, it also easier to identify the
interfaces that have been already configured as well as the interfaces that has not been assigned with an IP
address.
Pinging of PC to defined interface of the network
Problem - The configuration of the devices was done by assigning IP address to the interfaces of devices in the
network. However, during initial testing it was found that some devices did not respond to the “ping” which
means that the configurations were not appropriate.

15OVERVIEW OF INTERNETWORKING
Solution - This issue was resolved by checking configuration of the device interfaces that did not respond to
“ping”. The IP addresses of the various interfaces were checked thoroughly to determine the fault occurred
while assigning the IP address for the interfaces. The IP address of the interfaces were corrected by checking
the appropriate subnet mask.
5. Analysis of the current network
In context to the current network configurations, it can be said that the designed network can be implemented
in businesses to:
 Create a safe network for guest access: This means that the current network configurations can be
used for separating the traffic of guest users from the network assets of the company.
 Grouping of employees in the organization: It will help to group the employees based on the use of
same data-intensive applications.
 Restrict access to highly sensitive data: The access to sensitive data can be restricted by separating
essential departments like Finance and HR from the rest of network.
