5.2 Managing the Cisco File System  
  5.2.3 Managing configuration files using TFTP  
In a Cisco router or switch, the active configuration is in RAM and the default location for the startup configuration is NVRAM. In the event the configuration is lost, this startup configuration should be backed up. One of these backup copies of the configuration can be stored on a TFTP server. The copy running-config tftp command can be used to do this. The steps for this process are listed below:
  • Enter the command copy running-config tftp.
  • At the prompt, enter the IP address of the TFTP server to store the configuration file.
  • Enter the name to assign to the configuration file or accept the default name.
  • Confirm the choices by typing yes each time.

Loading the backup configuration file from a TFTP server can restore the router configuration. The steps below outline this process:

  • Enter the command copy tftp running-config.
  • At the prompt, select a host or network configuration file.
  • At the system prompt, enter the IP address of the TFTP server where the configuration file is located.
  • At the system prompt, enter the name of the configuration file or accept the default name.
  • Confirm the configuration filename and the server address that the system supplies.
