The paper mainly focuses on the case study that reflects on the local area network design as well as configuration. It is found that the e-commerce based organization, which is present generally goes through expansion which is mainly a merger of two different small business. Due to merger of the two business together, the organization is moving to a new building. It is found that the building has three floors where the ground floor is for the reception, warehouse as well as foyer whereas the second floor is for the office. The 1st floor of the building mainly consists of five offices. It is identified that each floor of the organization requires wireless connectivity and for providing wireless connectivity the organization requires a new LAN plan, design as well as implementation before they move to the new facility.
The paper mainly focuses on the design of a local area network for the case scenario. The paper also provides detailed set up for the network devices as well as detailed implementation report that includes configuration of each of the network device. In addition to this, the paper focuses on the configurations of the network device.

The diagram that is provided above is the network design for the organization. It is found that the organization merges with other two small business and thus this expansion requires a new building. The expanded organization will mainly consist of 100 employees. The design that is made for the building mainly consists of router, switches, access points as well as PCs. It is found that ISP which is known as internet service provider is mainly connected with the router of the building. The main router is connected with all the floors of the building with the help of 3 routers that are present in three different floors. The router that is present in the ground floor is mainly connected with the main switch of the ground floor. The main switch is mainly connected with reception, foyer as well as warehouse. The ground floor mainly requires of 5 data access points in reception, two in foyer as well four in warehouse. Similarly, it is found that the main router is connected with the router of the first floor which further is connected with the main switch of the first floor. It is found that in the first floor, switch is used for providing internet connection to all the five offices whereas the access point is mainly utilized for connecting smartphone and other devices. In addition to this, it is found that the main router is connected with the router of second floor which is turn connected with the switch. All the offices of the second floor receive the service of internet connection with the help of switch. Moreover, the second floor requires four data access for meeting rooms. Additionally, each and every individual are provided with atleast two data points. The entire building is provided with wireless connectivity so that the organization can be able to work properly and can be able to perform without facing any issues. The diagram that is provided above reflects the entire set up as well as connections that are generally needed for designing the Local area network design. It is found that the network design that is created is helpful in providing proper internet facility.
The device configuration for the entire network design is provided below:
