Create a network infrastructure diagram
Assessment
Report with either a diagram or screenshots from Cisco Packet Tracer
must include:
network devices
appropriate topology
appropriate symbols and variations
servers and clients
network addressing
Easily done in Cisco Packet Tracer during the Firewall lesson.
Make sure to include all the points that are must include and refer to the key below.
The key below shows:
1. Network devices - by default Cisco Packet Tracer will do this (nothing extra to do here)
2. Appropriate topology - arrange the devices in either a Bus, Star, or Ring and then Create a heading for it
3. Appropriate symbols and variations - by default Cisco Packet Tracer will do this for you (nothing extra to do here)
4. Servers and clients - Make sure you label each PC or laptop as a Client
5. Network addressing - Make sure you put the IP addresses of the Server and Client machines
Network Infrastructure Diagram for a Small to Medium-sized Business
Network Infrastructure Diagram for a Small to Medium-sized Business
Legend:
Router: A circle with four arrows pointing outward.
Switch: A square.
Server: A tower-like rectangle or use server rack symbol.
Client PC: A monitor and keyboard symbol.
Firewall: A wall symbol with a flame on it.
Cloud: Cloud symbol representing the internet.
Layout and Symbols:
Top of the Diagram: Place a cloud symbol at the top to represent the Internet.
Below the Cloud: Draw a line connecting the cloud to a wall symbol with a flame, representing a Firewall.
After the Firewall: Connect a line from the Firewall to a circle with four arrows pointing outwards, representing a Router.
Below the Router: Draw lines from the Router to squares which represent Switches. You can use one or more based on requirements.
Connected to Switches: Draw lines from each switch to server icons (tower-like rectangles) and client PCs (monitor and keyboard symbols).
Labeling: Next to each device symbol, write down its network address.
Topology:
Star Topology: All devices connect to the switches, which then connect to the router. This is the most common topology for small to medium-sized networks.
Addressing:
Internet Cloud: Public IP Address (e.g., 8.8.8.8)
Firewall: External: Public IP, Internal: 192.168.1.1
Router: WAN: 192.168.1.1, LAN: 192.168.2.1
Switch 1: 192.168.2.2
Switch 2: 192.168.2.3 (if applicable)
Server: 192.168.2.10
Client PCs: 192.168.2.11, 192.168.2.12, 192.168.2.13, etc.
By arranging and labeling these elements properly, you'll create a network infrastructure diagram that not only helps in visualizing the current setup but also in troubleshooting and expanding the network in the future. This is a simplified version, but you can make it more complex based on the actual needs.
