Before configuring your network devices, first of all you need to configure the IP addresses for the end devices:
Personal Computers (PCs)
Printers
Servers
Here’s the full addressing plan for the agency together with a list of VLANs.
Wow, that’s so complicated!
Don’t worry, we’re going to simplify it for you. I’m even going to be kind enough to give you the full addressing plan for our model in Cisco Packet Tracer. We’ll come back to the VLAN concept a bit later in the course.
I've already been through the subnets you need for the network diagram and I’ve left out the VLAN part, which we’ll look at later:
Groups | Network address | First available address | Last available address | Network gateway |
Executive | 192.168.20.0/24 | 192.168.20.1 | 192.168.20.253 | 192.168.20.254 |
Sales | 192.168.21.0/24 | 192.168.21.1 | 192.168.21.253 | 192.168.21.254 |
HR | 192.168.22.0/24 | 192.168.22.1 | 192.168.22.253 | 192.168.22.254 |
Accounting | 192.168.23.0/24 | 192.168.23.1 | 192.168.23.253 | 192.168.23.254 |
Operations | 192.168.24.0/24 | 192.168.24.1 | 192.168.24.253 | 192.168.24.254 |
Marketing | 192.168.25.0/24 | 192.168.25.1 | 192.168.25.253 | 192.168.25.254 |
IT | 192.168.27.0/24 | 192.168.27.1 | 192.168.27.253 | 192.168.27.254 |
Servers | 192.168.30.0/24 | 192.168.30.1 | 192.168.30.253 | 192.168.30.254 |
Printing | 192.168.40.0/24 | 192.168.40.1 | 192.168.40.253 | 192.168.40.254 |
Phew! Well, that should be a bit clearer now.
Configure the PCs
Okay, I’m going to give you the IP addresses, subnet masks in CIDR notation and the network gateways that you’re going to configure on the PCs. We’ll deal with the other end devices afterwards (servers and printers).
Groups | PC1 | PC2 | Network gateway |
Executive | 192.168.20.1/24 | 192.168.20.2/24 | 192.168.20.254 |
Sales | 192.168.21.1/24 | 192.168.21.2/24 | 192.168.21.254 |
HR | 192.168.22.1/24 | 192.168.22.2/24 | 192.168.22.254 |
Accounting | 192.168.23.1/24 | 192.168.23.2/24 | 192.168.23.254 |
Operations | 192.168.24.1/24 | 192.168.24.2/24 | 192.168.24.254 |
Marketing | 192.168.25.1/24 | 192.168.25.2/24 | 192.168.25.254 |
IT | 192.168.27.1/24 |
| 192.168.27.254 |
Configure the Printers
Printers are on a separate subnet, so you’re going to configure the IP addresses as follows:
Prn-Exec | Prn-Sales | Prn-HR | Prn-Acc | Prn-Ops |
192.168.40.1 | 192.168.40.2 | 192.168.40.3 | 192.168.40.4 | 192.168.40.5 |
Prn-Mktg | Prn-IT |
192.168.40.6 | 192.168.40.7 |
Configure the following IP parameters for the printer subnet mask and default gateway:
Subnet mask | Default gateway |
255.255.255.0 | 192.168.40.254 |
Configure the Servers
Servers are also on a separate subnet. You're going to configure the IP addresses, subnet mask, and gateway as follows:
AD-Server | App-Server | File-Server | Gateway |
192.168.30.1/24 | 192.168.30.2/24 | 192.168.30.3/24 | 192.168.30.254 |
Now you have all of the information, I’m going to show you how to configure IP addressing for a desktop computer, a printer, and a server. After that, it’s over to you to work it out for yourself!
Let’s now check that the end devices are communicating properly with each other. Let’s run a few tests on our model in Packet Tracer.
Well, only a few tests were conclusive, but that’s fine. We haven’t yet configured all of the connectivity devices.
Let's Recap!
In this chapter, you’ve seen:
how to configure end devices in Cisco Packet Tracer.
how to test communication between end devices in Cisco Packet Tracer.
Now that you’ve configured the IP parameters in Cisco Packet Tracer, you can add some more network devices, such as a WiFi access point. Find out how in the next chapter.
