In the previous video, we already learn about how switch and router work. 2
The summary is that switch is used to connecting many computer that in the same 3
block subnet. And router is used to connecting many computer that in the different block subnet. 4
And then, now in this video, we are going to practice about switch in cisco packet tracer. 5
Let’s just start! 6
Let’s import a switch to our project. Go to network devices, here we can see a router, 7
switch, hub, wireless, and others. Click on the switch. Here we can use cisco switch 2960. 8
Next let’s add some pc. Go to end device, and add some more pc. Let’s say here we want to have 5 pc. 9
And here we can remove cable between pc0 and pc1. 10
Now let’s connecting all of the pc to the switch. 11
Okay now all of pc already connected to the switch. 12
Next let’s configure the ip address of all pc with the same block subnet. Let’s say 13
we will use the first block subnet. Let’s start with pc0, 14
the ip address is 10.10.10.1, and the subnetmask is 255.255.255.224. next for pc1, 15
the Ip address is 10.10.10.2 and the subnetmask is correct. 16
Okay next for pc2, the ip address is 10.10.10.3 and the subnetmask is 255.255.255.224. 17
Next for pc3, the ip address is 10.10.10.4 and the subnetmask is 255.255.255.224. and last, for pc4, 18
the ip address is 10.10.10.5 19
and the subnetmask is 255.255.255.224. Okay we have done configuring ip address for all pc. 20
Now let’s test the connection between all pc. Here we can test using packet. 21
Let’s test from pc0 to pc1. 22
Okay here we can see that the result is successful, here we can see many result, 23
we can just delete it. Now let’s test again from pc0 to pc1, okay success, from pc1 to pc2, 24
also success, from pc3 to pc4, also success, and from pc4 to pc5 also success. 25
Okay so now all pc can communicate 26
each others. This is because all of pc is in the same block subnet. 27
For the testing, now let’s change the ip address of pc4. 28
Let’s say we want to change to 10.10.10.40, and if we see our calculation before, 29
10.10.10.40 Is in the second block subnet. so pc4 should not be able to communicate with others pc. 30
Let’s send packet from pc4 to pc3, here we can see that the result is failed. 31
Now let’s test again from pc4 to pc2, also failed. From pc4 to pc0, 32
and this is also failed. Okay, so remember that switch is used to connecting many pc 33
that is in the same block subnet. If there is a pc that in the different block subnet, 34
so that pc can not communicate with other pc. 35
Okay now let’s change the ip address of pc4 again, 36
let’s change this to 5 again. Let’s try ping from pc3 to pc4, and okay now the result is success. 37
Okay I think enough for this video. In the next video, we are going to practice with router. 38
