To empty the startup configuration on a Cisco device, you can use the command erase startup-config
in privileged EXEC mode. To remove the running configuration, you can use the command write erase
followed by reload
to restart the device, which will clear the running configuration and load the default settings. Remember to save any necessary configurations before performing these actions, as they will result in data loss.
wr or copy running-config startup config
To show the contents of NVRAM on a Cisco switch, you can use the command show startup-config. This command displays the startup configuration file stored in NVRAM, which contains the settings and configurations that the switch will use when it boots up.

On a Cisco switch, NVRAM (Non-Volatile Random Access Memory) is typically located within the switch's internal storage. It is used to store the startup configuration file, which is loaded when the switch boots up. You can access and manage the contents of NVRAM through the command-line interface (CLI) using commands like show startup-config and copy running-config startup-config.
The startup configuration will be erased and if the router is restarted will boot with no configuration.
If you want to make the saved configuration the current configuration, essentially undoing configuration changes since you last saved, you can use:copy start runcopy startup-config running-config
In order to see the running configuration on a Cisco 2600 router, follow these steps from user executive mode.RouterName> EnableRouterName# show run
This command will allow you to copy a configuration from a TFTP server to the running configuration of a Cisco device. When you issue the command you will be prompted for further details about the TFTP server. The new configuration will replace the active one (or running configuration) and make any necessary changes.
startup-config resides in NVRAM and running-config resides in RAM.
This command will copy the running configuration (located in RAM) of a Cisco device to a TFTP server. After executing the command you will be prompted for further information about the TFTP server (Server Address, file name, etc.).
When a Cisco router is booted up for the first time, or is reloaded, the router will look into its Non-Volatile RAM (NVRAM) for the startup configuration file. Setup Mode is usedto configure a Cisco router or switch after start up to create a startup configuration file.
