Documentation Development (Instructor Version)

Instructor Note: Red font color or Gray highlights indicate text that appears in the instructor copy only.

Objective

Using a systematic approach, troubleshoot issues in a small- to medium-sized business network.

Instructor Note: This activity is best completed in small groups. It can then be shared with another group, the

class, or the instructor (as a group project).

Scenario

As the network administrator for a small business, you want to implement a documentation system to use with

troubleshooting network-based problems.

After much thought, you decide to compile simple network documentation information into a file to be used when

network problems arise. You also know that if the company gets larger in the future, this file can be used to export

the information to a computerized, network software system.

To start the network documentation process, you include:

 A physical diagram of your small business network.

 A logical diagram of your small business network.

 Network configuration information for major devices, including routers and switches.

Resources

 Packet Tracer software

 Word processing software

Step 1: Create a Packet Tracer file to simulate a very small business network. Include these

devices:

 One router with at least two Ethernet ports

 Two switches connected to the router (LAN1 and LAN2)

 Five user devices to include PCs, laptops, servers, and printers connected either of the two LANs.

Step 2: Create a word-processing file in matrix format to record each of the following main

network-documentation areas:

a. Physical topology and information

1) Type of device and model name

2) Network hostname

3) Location of the device

4) Cable connections types and ports

b. Logical topology information

1) IOS or OS image versions

2) IP addresses (IPv4, IPv6, or both)

3) Data-link addresses (MAC)
