Lab 3.1.2 Creating a Logical Network Diagram

Task 1: Use Cisco IOS Commands to Obtain Information about the Network

Step 1: Discover and document the first device
a. Your instructor will advise you as to which PC is configured for Administrator access to the network.
Access this Admin PC and issue the ipconfig command from the command prompt to discover the
default gateway.
b. Telnet from the command prompt (or use a terminal program such as HyperTerminal or TeraTerm) to
the IP address of the gateway device and enter privileged EXEC mode using the passwords given
above.
c. Issue Cisco IOS commands, such as those shown here as well as others you choose to use, to learn
about the device.
show running-config
show ip route
show interfaces
show ip interface brief
show version
Record this information in the first Device Table at the end of this lab.
d. Issue Cisco IOS commands such as those shown here to discover information about connected
devices.
show cdp neighbors
show cdp neighbors detail
It may take a few minutes for the network to converge. If you do not see any neighboring devices
initially, repeat the command until you do.
Document the information you gather in the appropriate Device Tables.
e. Close the Telnet session by issuing the exit command.
Step 2: Discover the remaining devices
a. Telnet to the IP address of a device connected to the first device interrogated, and repeat the process
in Step 1. Document this new device in an appropriate Device Table.
b. Repeat this process until all devices in the network are discovered and documented.
As you work through the network devices, record the details of each and sketch a diagram of the
network devices and their interconnections. When IP address information has been recorded, what other commands could be used to confirm connectivity and trace interconnections between devices?
ping
tracert dan traceroute
Can a connectivity trace be relied upon to return details of all the pathways between devices? Give
reasons for your response.
Tidak, semua jalur tidak akan dikembalikan karena routing pada Layer 3 dan STP pada Layer 2 akan menyebabkan hanya satu jalur antara perangkat yang akan ditampilkan jika koneksi berlebihan atau ada alternatif.

Task 2: Use Cisco Network Assistant to Obtain Information about the Network

Step 1: Launch Cisco Network Assistant
a. Launch the Cisco Network Assistant program on the PC connected to the network.
b. Network devices can be accessed for monitoring and information gathering. From the Applications
menu, click Connect.
c. In the Connect dialog box, select the Connect To: option and enter the default gateway of the Admin
PC in the field, as shown.
Step 2: Record the network topology

1. Record the displayed topology. The display will look similar to this sample.
2. Continue to connect to each known device. Record the topology displayed and compare it with the diagram that you created from the results of Task 1.

Step 3: Collate the network information
Assemble your completed network Device Tables and Topology Diagrams into your FilmCompany case study portfolio for use in later labs.

Step 4: Clean up
Erase the configurations and reload the routers and switches. Disconnect and store the cabling. For PC hosts that are normally connected to other networks (such as the school LAN or to the Internet), reconnect the appropriate cabling and restore the TCP/IP settings.

Task 3: Reflection
a. These techniques were used to discover and document an enterprise LAN. Would the same
techniques work for an enterprise network that included WAN links?
b. Could these techniques be used in a network that included routers and switches from a manufacturer
other than Cisco? Why or why not?
Jawab:
Cisco Network Assistant hanya mendukung perangkat yang tercantum di FAQ program. Jenis-jenis perangkat lunak dapat digunakan untuk jaringan multi-brand.
