4. Steps for trouble shooting
While configuring the devices those have been used for designing the network are as follows:
Interface identification
Issues: In order to make the network configuration accurate it is necessary to determine the interfaces
properly for each device. This is referred to as one of the major activities that must be done properly. However,
the identification of accurate interfaces for the different devices are a quite problematic job.
Solution: For resolving these particular issues, it is necessary for the system developers to use a command
named as “Show Interface”. With the help of this command the present issues associated to the devices could
be identified easily. Even the interfaces those are already configured can also be identified with the help of this
command. In addition to this, the non-assigned interfaces assigned with the IP addresses can also be identified
with this command.
Pinging of PC to defined interface of the network
Issue: By assigning the IP addresses with the interface of the devices the network design is configured.
However, in the initial testing phase it is identified that, all connected devices are not responding properly with
the “Ping” which implies that the configuration is not correctly done.
Solution: In order to resolve these issues, all the interfaces are required to be rechecked properly by the
network developers. It will help the interface designer to identify the issues and solution according to it.
Through the implementation of the subnet masking IP addresses could be corrected accordingly.
5. Current network analysis
After considering the current network configuration it has been defined that this particular network can be
deployed in the businesses for the following components:
 It helps to create safe access for the guests

 It helps to organize employees in the organization
 Sensitive information cannot be accessed due to improved system configuration
