Backing up the configuration file locallyThe boot configuration files for both the switch and router are stored in NVRAM; when the IOS device boots, the IOS will load the configuration from NVRAM into memory. However, as mentioned in the "Running and Startup Configurations" section, the running configuration in memory is not automatically saved to NVRAM: if you shut down the IOS device without saving the configuration, the latest changes made to the configuration will be lost. To save the active configuration to NVRAM, you must execute the privileged EXEC mode command copy running-config startup-configigo When you execute this command, the IOS device will save the active configuration in memory to NVRAM, and in the process, overwrite the old configuration file in NVRAM. The followingis an example of how to use this command.IOS# copyrunning-config startup-config Destination filename [startup-config]? Building configuration... [OK] IOS#When you execute this command, you will be asked to assign a filename to the configuration file - think startup.config, which is what IOS looks for when booting. To provide multiple versions of the configuration backup, you can change the file name of the configuration file, but you must ensure that the latest configuration file is named startup.config. On IOS devices, to view the configuration stored in NVRAM, use the privileged EXEC mode command show startup-config0Practical Experience A shortcut to save the IOS configuration to NVRAM is the command writememory can be abbreviated to wro However, this command is not supported in the mock exams. On actual IOS devices, I always use wr to quickly save the configuration. To view the configuration file stored in NVRAM, use the following command.Router# showstartup-config Using 4224 out of 65536 bytesversion 11.3 no service udp-smal1-servers no service tcp-small-serversThe difference in the above output compared to the output of the command showrunning-config is that line 1 Using 4224 out of 65536
