Restoring a configuration from backup
When you restore a configuration from backup and add to the running configuration, the zone configuration identified in the backup copy as the enabled configuration becomes the new enabled configuration.
In privileged EXEC mode, enter the copy command. For the source file use the file where the saved configuration is stored. For the destination file, use running-config.
This operation updates the defined configuration in RAM.
The following example adds the configuration in the file named myconfig on the attached USB device to the defined configuration.
switch# copy usb://myconfig running-config
