Creating a Simple Network with Cisco Packet Tracer

Here I will create a computer network consisting of:
* 21 computers
* 3 switches
* 1 server
Each switch is connected with 7 computers. And each computer has an IP address with the same level and group. The end view will be like this

The steps for creating a network are as follows:

  • Make 3 switches.

The switch can be found on the bottom toolbar, in the SWITCHES section. Select any type, each type represents the types of switches issued by Cisco.

  • Make 7 computers on each switch, so there are 21 computers connected with 3 switches. The computer can be found on the END DEVICE toolbar.

The arrangement of each computer does not have to be the same as the image I made, the most important thing is that each computer is connected to the correct switch. After 21 computers have been created, then connect the computers to the switch. Because the two connected devices are different, use the straight cable as the transmission medium.

When the computer is first connected with a cable to the switch, the green circle on the switch will be yellow. This indicates that the relationship is still initialized, if the transmission media used is correct then over time the indicator will change color to a green circle but if it is wrong it will be red.

  • Connect each switch with the switch in the middle, consuming the cross cable.
    Why is the media used cable cross? Because the function of cross is to connect between the same two devices. Cross cables can be found on the CONNECTIONS toolbar.

Just as explained above, wait until the indicator is green, indicating the connection between the devices is connected.

  • Make 1 server that is connected to the switch in the middle.

The server can be found on the END DEVICE toolbar. Connect the server with the switch using a straight cable. Servers here can be used as data storage (data warehousing) or central processing (all processes are carried out by the server).
The physical settings for the network have finished here. All devices are physically connected. To transmit data, a unique address is needed on each connected computer. This is done so that the data is sent according to the target and the switch can determine where the data is sent.
There are 2 types of IP Address:

ยท Static IP

ยท DHCP (IP dynamic)

For now we will configure static IP. The steps are as follows:

  • Click the computer that you want to configure its IP address, then a new window will appear.
  • Click the Desktop tab,
  • The menu will appear, select IP Configuration,
  • Fill in the IP Static section with and the gateway leave by default,
  • For the second IP computer, fill in The third computer is filled with and so on until computer 21,
  • Repeat steps 1-5 until all computers have different IP addresses.

After all computers have configured their IP Address, it is time to find out whether the network is fully formed or not, by pinging the opposite computer. In a way,

  • Click the computer that wants to ping another computer, then a new window will appear.
  • Click the Desktop tab,
  • Enter the Command Prompt menu,
  • And type the command,
    Ping The destination computer’s IP Address.
  • Ping success indicates the data communication path between the two devices that are connected and ready to use.

Display of ping / message from computers connected in the network.
The following image is taken based on PC-0 which is the transmitter and all computers other than PC-0 as receivers.
