4.2.3 Copying Configuration Files from a Network Server to the IC35516
You can copy configuration files from a TFTP server to the running configuration or startup configuration of the router.
You may want to do this for one of the following reasons:
1. To restore a previously backed up configuration file.
2. To use the same configuration file for another router. For example, you may add another router to your network
and want it to have a similar configuration to the original router. By copying the file to the new router, you can
change the relevant parts rather than re-creating the whole file.
3. To load the same configuration commands onto all the routers in your network so that they all have the same
configurations.
The
copy tftp running-config
command loads the configuration files into the router as if you were typing the
commands in at the command line. The router does not erase the existing running configuration before adding the
commands unless a command in the copied configuration file replaces a command in the existing configuration file.
For example, if the copied configuration file contains a different IP address in a particular command than the existing
configuration, the IP address in the copied configuration will be used. However, some commands in the existing
configuration may not be replaced or negated. In this case, the resulting configuration file will be a mixture of the
existing configuration file and the copied configuration file, with the copied configuration file having precedence.
In order to restore a configuration file to an exact copy of a file stored on a server, you need to copy the configuration
file directly to the startup configuration (using the
copy tftp startup-config
command) and reload the router.
To copy a configuration file from a TFTP server to the router, use one of the following commands in EXEC mode:
Command Purpose
copy
tftp:
[[[//location]/directory]/filename]
running-config
copy
tftp:
[[[//location]/directory]/filename]
startup-config
Copy a file from a TFTP server to the router.
