1. Verify that all the parameters configured are recorded. If not, analyze the output and determine which commands were not executed or were entered incorrectly. You can also click Check Results in the instruction window.

Step 2: Optional: Save the startup configuration file to flash.

Although you will be learning more about managing the flash storage in a router in later chapters, you may be interested to know that, as an added backup procedure, you can save your startup configuration file to flash. By default, the router still loads the startup configuration from NVRAM, but if NVRAM becomes corrupt, you can restore the startup configuration by copying it over from flash.

Complete the following steps to save the startup configuration to flash.

1. Examine the contents of flash using the show flash command:

Questions:

How many files are currently stored in flash?

Type your answers here.

Which of these files would you guess is the IOS image?

Type your answers here.

Why do you think this file is the IOS image?

Type your answers here.

Answers may vary, but two clues are the file length compared to the others and the .bin at the end of the file name.

1. Save the startup configuration file to flash using the following commands:

R1# copy startup-config flash

Destination filename [startup-config]

The router prompts you to store the file in flash using the name in brackets. If the answer is yes, then press ENTER ; if not, type an appropriate name and press ENTER .

Why Does The Router Respond With The Startup-Config Is Not Present Message?

Answer: The router responds with the message because the file is present in the RAM and not saved in the NVRAM when someone wants to save it in NVRAM.

Let us discuss the configuration of the default router, the verification of the initial router configuration, and save the running file.at first, the router configuration begins and with the help of the encrypted and text message you would secure the CLI and console port, the message configuration with the help of the login is also performed in this topic. In the end, you would learn to save the running file.

Configuration of the default route:

1. Create the console connection with R1

• Select the console.
• Tap on PCA and choose RS 232.
• Tap R1 and choose console.
• Tap on PCA>desktop tab> terminal.
• Tap on OK and press enter.

1. Step on the privileged mode and determine the recent configuration.

Because there are many configuration commands that’s why it needs to be protected with passwords and the username to prevent the unknown person who has no access to it.

1. With the help of the enable command enter EXEC mode.

• Router>enable.
• Router #.
• Focus on the prompt change in the privileged node configuration.

1. Step on show running-config command:

• Router # show running-command,

1. Give the explanation of the question:

• The router’s name.
• The number of fast ethernets the router has.
• The gigabit of the ethernet.
• A number of the serial interface of the router.
• Range of the vty line.

1. Show the content of NVRAM.

• Router# show startup-config.
• Startup-config.

Verification and the configuration of the initial router:

For the configuration, you have to go to the different modes so always focus on the prompt change of the router.

1. Determine the setting of R1.

a.R1 the hostname.

b.Use the following password:

• Console: letmein.
• Privileged EXEC unencrypted: cisco.
• Privileged EXEC encrypted: itsasecret.

c.Transform or encrypt the text.

d.Type message: an unauthorized person is not allowed.

2. Verify the R1 setting:

1. Check the setting by the look of the R1 configuration and the command for it is shown running-config.
2. Type the recent session of console until:

• R1 con0 is present.
• Tap return to start it.

3. Press enters and the following messages are displayed:

• An unknown person is not allowed.
• password.
• Use the verification for access.

Save the file currently running

Step 1: Save the file which is configured to NVRAM.

1. As you have already determined the initial R1 setting move toward the configuration of the running file in NVRAM to make sure the changes are saved if the system is damaged.

• What is the command to save the configuration to NVRAM? Copy running-config startup-config.
• The short version of the command? Copy r s.
• The command for the NVRAM content: show startup-configuration or show start

2. Check that the changes are recorded and if it is not the situation then check the output and check the missing command and if it is entered incorrectly.
