Which Information Does The Show Startup-Config Command Display?

The show startup-config command will display all the contents of the saved configuration file in the NVRAM. Today, let us learn about the startup-config command in detail. We can copy the configuration from the RAM to the NVRAM. This can be done by using the copy config startup-config, this can replace the configuration that is stored in NVRAM. The NVRAM stands for nonvolatile random access memory. We can also able to copy the configuration of a TFTP server.

It allows copying the configuration of both running and the startup configuration. When we try to copy the information from the ram to the NVRAM, it will override the configuration by taking a copy from the NVRAM or by a startup to RAM.

If we want to differentiate between the show startup configuration and the running configuration, we can type show config on the command prompt, this will show the startup configuration. when we type config T we can able to change the IP address to not giving any IP address.

Now, let us learn in detail about the basic commands. The first one shows the startup-config command. Now, to know whether the show startup configuration is present or not, we need to type show startup-config on the command prompt. After pressing the enter, if the startup-config is not present it displays as startup-config is not present. The reason to display the above content is that we didn’t copy the running configuration to the startup configuration.

The second type of the command is called running configuration, when you type the show running configuration on the command prompt we can able to see the running-config on the command prompt. Now, let us learn how to copy from the running configuration to the startup configuration.

Now type copy running-config startup-config on the command prompt and then press enter. Then it will ask the destination file name, now type Y. If it shows any error, use another command called write memory on the command prompt.

After pressing enter, it displays as building configuration (OK). After this in order to recheck, we can use the command show startup-config, nowhere we can see the startup-config. And if we want to erase the startup configuration, we can use the command called erase the startup-config and it displays has as we are sure to remove. Then Type Y on the command and press enter. Now, it will completely remove all the configuration files.

And to check it is erased or not, simply use show startup-config and press enter, now if the startup command has successfully been removed then it displays as startup-config is not present.

We have another command called as history command, which will show all the operations that are performed previously. And we have show terminal, this will show the most recent ten items that we are used.

We can also increase the size of the history and terminal by using the command called as show terminal history size is and write the size number that you want to increase. In this way, we can increase the size of the history and terminal.
