How to Create a LAN Network Using Cisco Packet Tracer

A LAN or Local Area Network is a computer network whose network coverage area is very small and limited. Examples of LAN networks are usually in places that have only one room or different rooms but are still within the network radius coverage such as offices, computer laboratories at schools, homes or internet cafes.

The most widely used LAN network technology is the IEEE 802.3 Ethernet technology and is equipped with additional components such as switches and hubs that have data transfer speeds of 10, 100, or 1000 Mbits / second. In addition to LAN Ethernet technology, hotspots on smartphones can also be used to form a LAN network, this type of technology is 802.11b (Wi-fi) technology, which can provide Wi-fi-based LAN technology.

If you want to create a LAN network, you have to prepare carefully a few things that must be needed such as this:

  • Cost
  • Device components
  • Device placement
  • Network topology used
  • And of course also the allocation of the IP Address.

In addition, a network simulation simulation is also needed, this is important so that later we can see an overview of how the network is arranged, then so that some system failure problems do not occur and also in order to optimize the network for the better.

Cisco Packet Tracer is a Cisco product network device simulation software that is widely used as a learning medium and training before using the original device, this Cisco Packet Tracer software was made directly by Cisco Systems and is provided free of charge for students and network administrators who want to learn it. You can download this Cisco Packet Tracer software on the official website of Netcad Cisco Packet Tracer.

In this article, we will learn how to create a LAN network using Cisco Packet Tracer as follows:

  • First open the Cisco Packet Tracer application, here I am using CPT version 6.3
  • Here is a look at the start page of the Cisco packet tracer.

Here we will create an example of a LAN network using a star topology, the devices needed include:

  1. 4 Computers
  2. 4 Laptops
  3. 1 Switch Type Empty
  4. Straight cable
  • Prepare computers, laptops, and switches by selecting devices in the fields as marked below. Because we will use a star topology, adjust the position according to your wishes, try to provide a direct cable installation path to connect each computer, laptop with a switch so that it resembles a star where the switch is the center node.
  • Before installing the cable, because the Switch type is empty, we have to manually load the LAN Card connector. Click on the switch then select the Physical menu and in the module select the type of LAN Card which ends in 1CFE, to load the LAN Card you must first turn off the electrical power of the switch so that it does not get electrocuted and remains safe, (so even though it is a simulation, this CPT simulation is like native practice). If it’s turned off then drag the LAN Card to the empty area on the switch, adjust the number of connectors with the number of computers and laptops you want to connect to.
  • When it’s finished installing, you can turn the switch back on.
  • Now is the time to connect the computer to the switch using a cable, the cable for the connection uses a straight type cable for installation of the cable, click the straight cable image below then click again towards the intended PC and select FastEthernet0 then point the cable at the switch.
  • On the switch, several port options will appear, you are free to choose which one but I suggest you have to select the port in order so that later the cable can be structured, easy to remember and not confusing.
  • If you have the following are the results of the appearance that I made.
  • The green color on the cable indicates that the devices are connected to each other, but cannot send data from one PC to another.

In order to be able to send data to each other, all you have to do is enter the IP Address on each PC and Laptop. Here is the allocation of the IP Address for each PC and Laptop

  1. (PC0) => IP : 192.168.1.2 => Subnet Mask : 255.255.255.0 => Gateway : 192.168.1.1
  2. (PC1) => IP : 192.168.1.3 => Subnet Mask : 255.255.255.0 => Gateway : 192.168.1.1
  3. (PC2) => IP : 192.168.1.4 => Subnet Mask : 255.255.255.0 => Gateway : 192.168.1.1
  4. (PC3) => IP : 192.168.1.5 => Subnet Mask : 255.255.255.0 => Gateway : 192.168.1.1
  5. (Laptop0) => IP : 192.168.1.6 => Subnet Mask : 255.255.255.0 => Gateway : 192.168.1.1
  6. (Laptop1) => IP : 192.168.1.7 => Subnet Mask : 255.255.255.0 => Gateway : 192.168.1.1
  7. (Laptop2) => IP : 192.168.1.8 => Subnet Mask : 255.255.255.0 => Gateway : 192.168.1.1
  8. (Laptop3) => IP : 192.168.1.9 => Subnet Mask : 255.255.255.0 => Gateway : 192.168.1.1
  • For how to enter the IP Address, you can see the image below, please first click on the PC you want to enter the IP Address for, then select the Desktop menu and click IP Configuration as shown below.
  • Select static because we want to enter the IP manually, then enter the IP, Subnet Mask and Default Gateway. For the DNS Server, you can just leave it blank, a DNS Server will be needed when we want to surf the internet in a web browser. If you have clicked ok or you can close it immediately.
  • Please repeat the tutorial for entering the IP across all PCs and Laptops with the allocations I have provided above.
  • If you have finished configuring IP on all PCs and Laptops, the next step is to check the connection by clicking the message icon on the right of the display as shown below
  • Then navigate to the 2 PCs or laptops that you want to check the connection, and a notification of the connection check results will appear at the bottom right of the application, if the status that appears is Successful then the PC that was checked is connected properly and ready to send data to each other . However, if the status is Failed, there is still an IP configuration error.
  • If the above is to check the connection in the GUI, then this can be said to check the connection with the CLI display.
  • Click the PC you want to check the connection for then go to the Desktop menu and select Command Promt.
  • At the Command Prompt or CMD we must first know our original IP and destination IP that we want to check, to find out the original IP we can use the ipconfig command, now to check the connection or ping it, type the ping command (destination ip) Another PC, for example: ping 192.168.1.4 then just enter. If there is a reply notification as shown below, the PCs are properly connected to each other and ready to send data to each other. However, if the display is General Failure or the like, then there are still errors in the IP configuration.
