4. Steps for trouble shooting
During the network configuration the problems those have been faced by the system developers are as follows:
The interface identification
Issues: In order to make the configuration appropriate, the determination of the interfaces for different
devices, play most effective activity. However, the identification of accurate interface used in different devices
are other difficult issues those have been determined.
Solution: In any particular device, identification of the interface is very much difficult; however with the
implementation of “Show Interface” command the identified issues could be resolved completely. With the

16OVERVIEW OF INTERNETWORKING
help of this command the interface could be determined that have already been configured. Even the interface
those are not assigned with the IP addresses can also be identified.
Pinging if PC for determining the network interface
Issues: Through assigning the IP addresses with the devices, the network device configurations are done.
Though, in the initial testing phase it is defined that, some of the devices fail to respond on the “Ping“. It
implies that the configuration of the network is not appropriately done.
Solution: In order to resolve the issue, the non-responsive command on the ping should be rechecked. In order
to determine the occurred issues, each of the interfaces must be thoroughly checked. With proper checking
the issues of IP addresses can be defined easily. For resolving these issues subnet masking is required to be
done.
5. Current network analysis
Considering the current network configuration it has been determined that for business purposes also this
particularly configured network can be deployed. The purposes for which it could be developed in the business
are as follows:
 It helps to create safe network for the guests
 It helps to group the employees in an organization
 Sensitive data cannot be accessed due to high restriction
