How to Make Computer Lab in Packet Tracer?

Cisco Packet Tracer is a tool built by Cisco and it provides network simulation to practice simple and complex networks. The main purpose of the Cisco Packet Tracer is to help students learn the principles of networking and demonstrate the networking concepts. A DHCP Server is a network server that automatically assigns IP addresses, default gateways, and other network parameters to client devices. 

Step 1: Open the Cisco Packet Tracer. 

Step 2: After opening the CISCO packet tracer, add a switch, a server, and 20 PCs to the screen from the bottom left section for this project. 

Note: One can add any number of PCs but here we’re considering 20 PCs in a lab. 

Switch	1
Server	1
PCs	20

Step 3: Connect all PCs and the server with a switch by using a cable from the cable section.

Step 4: We’re considering the server as a DHCP server. Click on server, go to Desktop, and then click on IP configuration. Give an IP address, subnet mask, and default gateway to the server.

IP Address	192.168.1.1
Subnet mask	255.255.255.0
Default Gateway	192.168.1.254

Step 5: Click again on the server, click on the services section, and then go to DHCP. Turn on the DHCP services and then enter the default gateway, starting IP address, subnet mask, and a number of devices, and then SAVE it. Now, the DHCP server will automatically assign IP, subnet mask, etc. to the PCs.

Step 6: Click on any PC, go to Desktop, and then click on the IP configuration section. Click on DHCP and it will request the IP address, subnet mask, etc. from the DHCP server and it will automatically assign all these to the PC.

Step 7: Do this for all the PCs. One can also use the ping command to check the communication between all PCs. 

For example, From PC0

ping 192.168.1.15

This is how PCs are connected with the switch and server which assign all PC’s IP addresses. All PCs communicate with each other via a switch. One can take any number of PC in this project.
