17.8.1 Packet Tracer – Design and Build a Small Network – Physical Mode Answers
Explain how a small network of directly connected segments is created, configured, and verified.
In this Packet Tracer Physical Mode (PTPM) activity, you will design and build a network from scratch. Your design must include a minimum of one Cisco 4321 router, two Cisco 2960 switches, and two PCs. Fully configure the network and use IPv4 or IPv6 (subnetting must be included as a part of your addressing scheme). Verify the network using at least five show commands. Secure the network using SSH, secure passwords, and console passwords (minimum).
1. What was the most difficult portion of this activity?
Answers will vary.
2. Why do you think network documentation is so important to this activity and in the real world?
Documentation is imperative to good network management. Without it, network administrators have to recreate topologies, physically check addressing, etc. This takes time, which could be used elsewhere.
Create a small network of directly connected segments, at a minimum 1 router, 2 switches and 2 PCs, and include a screenshot of the network in your final documentation.
Configure the network to include switches, routers, and end devices and use your own network addressing.You must use subnetting of some type and you can use either IPv4 or IPv6 logical addressing. Create a table showing your physical addressing scheme for the router, switch, and PC and include it in your final documentation.
|Device Name||IP Address||Subnet Mask|
|Cap_rtr||G0/0/0 – 192.168.1.1
G0/0/1 – 192.168.1.33
|Cap_sw1||VLAN1 – 192.168.1.20||255.255.255.224|
|Cap_sw2||VLAN1 – 192.168.1.62||255.255.255.224|
|Cap_PC1||F0 – 192.168.1.10||255.255.255.224|
|Cap_PC2||F0 – 192.168.1 40||255.255.255.224|
Verify the network by using show commands (at least 5) to provide a performance baseline. Be able to discuss why you chose the show commands you selected and what the output means (use all Packet Tracer activities for modules 1-17). Keep screenshots of your output and include in your final documentation.

Secure the network using common configuration to include SSH, secure passwords, console security, etc. and verify the commands configured by enacting a show running-configuration screen as output. Include in your final documentation.
