Lab 11.5.3 Configure Host Computers for IP Networking
In this lab students will create a small network that requires connecting network devices and configuring host computers for basic network connectivity. The Appendix is a reference for configuring the logical network.
Note to instructor: To reinforce student cable identification, have several different types of cables available for the students. Mix cross-over, straight-through, and rollover cables. Students should be able to identify the proper cable type based on a visual inspection.

Lab 11.5.3 Configure Host Computers for IP Networking
Step 1: Physically connect devices.
1. Cable the network devices as shown in Figure 1.
Figure 1. Cabling the Network
Is a crossover cable needed to connect Host computers to the switch? Why or why not?
_____________________________________________________________________________
_____________________________________________________________________________
Answer: No. Since computers and the switch are not wired the same for networking, straightthrough cables are used.
If not already enabled, turn power on to all devices.
Step 2: Visually inspect network connections.
After cabling the network devices, take a moment to verify the connections. Attention to detail now will minimize the time required to troubleshoot network connectivity issues later.
Step 1: Document logical network settings.
1. Host computers will use the first two IP addresses in the subnetwork. Write down the IP address information for each device:
Device
Host1
Host2
Subnetwork IP address Mask

Answers will vary.
Note: If pings to host computers fail, temporarily disable the computer firewall and retest. To disable a Windows firewall, click Start > Control Panel > Windows Firewall , choose Off , and then click OK .
Review any physical or logical configuration problems encountered during this lab. Make sure you have a thorough understanding of the procedures used to configure a Windows host computer.
Ask your in structor or another student to introduce one or two problems in your network when you aren’t looking or are out of the lab room. Problems can be either physical (wrong UTP cable) or logical (wrong
IP address). To fix the problems:
1. Perform a good visual inspection. Look for green link lights on Switch1.
