Saving Configuration Changes
You need to enter the copy running-config startup-config command to save your configuration
changes to nonvolatile RAM (NVRAM) so that they are not lost if there is a system reload or power
outage. This example shows how to use this command to save your changes:
Router# copy running-config startup-config
Destination filename [startup-config]?
Press Return to accept the default destination filename startup-config, or enter your desired destination
filename and press Return.
It might take a minute or two to save the configuration to NVRAM. After the configuration has been
saved, the following message appears:
Building configuration...
Router#

command, check the prompt, and then enter the question mark (?) for a list of available commands.
You might be in the wrong command mode or using the wrong syntax.
If you want to disable a feature, enter the keyword no before the command; for example, no ip
routing.
Save your configuration changes to NVRAM so that they are not lost if there is a system reload or
