Introduction In this assignment, logical and physical design will be introduced and compared with each other. The main issue discussed and explained is the customer's requirements for the network to be designed. It's a system for a local educational institution with 50 lab computers, 35 staff computers, and 3 printers, all with dynamic IP addresses. Based on that request, a logical design will be provided along with a physical design and an IP address table. Next, a test plan will be created along with the evaluation of this network system, the solution will also be given to overcome the shortcomings. The network design process will be displayed along with the overall results table of the devices. Finally, show the results of the testing process and compare it with the customer's original request.
P5 Provide a logical/physical design of the networked system with clear explanation and addressing table
- The difference between logical and physical design Logical network design : Connections and interactions between network devices are described in logic diagrams. Relationships describe how devices connect to each other, how they collaborate to provide network services and support, and respond to user requests. (McCabe, 200 7). A physical design showing how devices are connected to each other in a network along with wires and cables. It reveals the network topology with everything physical: cables, servers, PCs, etc. It clearly describes the location of devices in a work environment such as a school or company. Figure 1 : Physical Topology Figure 2 : Logical Topology
switches are 48 ports (due to future development). Using multiple switches is due to the convenience of installation and the floors do not depend on each other. Finally, security is necessary to protect the information of employees, students and data in the network.
- Logical design Requirements are 50 PC-student, 25 PC-Staff, 3 Printers, 1 File server. Due to the large number of devices, the number on the logical design is representative only. The design has 3 floors and 6 rooms, including 2 routers and 4 switches. a) Floor 1 Includes 2 switches for 4 rooms. Switch SA_M is connected to the Admin room and the Manager room along with 4 PCs of the Marketing department. The IP address of this switch is 192.168.3.1/255.255.255.0 with VLAN 20 for connections. Switch ST_M is connected to Marketing department and Teacher room. The IP address of this switch is 192.168.4.1/255.255.255.0 with VLAN 10 for connections. These 2 switches are connected to the RS router. Figure 3 : Logical design
b) Floor 2 and 3 At floor 2, 25 lab computers are connected to the SLab1 switch with VLAN 30. The IP address of SLab1 is 192.168.1.1/255.255.255.0. Figure 4 : Floor 1 Figure 5 : Floor 2
The RS router acts as a dhcp server to provide dynamic IP addresses to the PCs, the RST router is configured with an IP helper so that the 1st and 2nd floor switches are assigned dynamic IP addresses by RS. The IP address of RS is 10.1.1.1/255.255.255.252, of RST is 10.1.1.2/255.255.255.252.

- The IP address table This is the actual IP address table, so it will provide the IP address for all devices.

Cons : No DNS, HTTP, Email service and internet connection yet. There is no firewall system, many servers are missing. The wireless network has not been integrated, making devices such as laptops and phones unable to connect. Equipment costs are not optimized. Solution : Set permissions to restrict access in rooms, for example, only Admin computers can ping all rooms in the network, computers in labs 1 and 2 cannot ping staff machines at floor 1. Increase the range of use of the network by adding wireless devices to the network. Add Internet service and HTTP, DNS, Email servers to the network. P7 - Implement a networked system based on a prepared design
1. Design routers, switches, devices for network. Because the logical design has only a few representative PCs, the number of ports connected will also differ from reality. Step 1 : Create VLAN for switch to use for devices. Create VLAN 20 on Switch SA_M for ports Fa0/1 to Fa0/9. Figure 10 : VLAN 20 for SA_M (Manager,Admin room)
Create VLAN 10 on Switch ST_M for ports Fa0/1 to Fa0/9. Create VLAN 30 on Switch SLab1 for ports Fa0/1 to Fa0/4. Figure 11 : VLAN 10 for ST_M (Marketing, Teacher room) Figure 12 : VLAN 30 for SLab1 (Lab 1 room)
Set IP addresses for ports Giga0/0, Ser0/1/0, Ser0/1/1 and no shutdown them and ospf 1 of the 2 routers. Also, set up the IP helper at the RST router so that the switches of this router are dynamically assigned IP addresses by RS. Figure 15 : IP address, IP helper and OSPF of router RST
Step 3 : Design ip dhcp pool at router RS. Design dhcp for R1Ga0, R1Ga1, R2Ga0, R2Ga1. They have “network” and “default-router”. Step 4: Design basic settings for the router such as password, name, exec-timeout, banner. Because the settings of these two routers differ only in the name, only a screenshot is displayed.
