In this case, I simply chose the default name, running-config. In larger environments, consider using a destination filename that uniquely identifies the router that the file is associated with. Notice that the command asked us to specify the location of the TFTP server (the address of the remote host). The example below shows the running configuration being saved to a TFTP server.Īddress or name of remote host ? 192.168.1.21ġ136 bytes copied in 5.100 secs (227 bytes/sec) To save the startup or running configuration to a TFTP server, enter the commands copy star tftp or copy run tftp respectively. After installing it on your laptop or a network server, you will ultimately reference it by its associated IP address. That way, if you mess something up, you can always just restore an old configuration file.Īny TFTP server software can be used. For example, it’s always a good idea to copy the startup configuration to a TFTP server prior to changing the configuration of a router. But why would you do this? Mainly to have a backup copy of the files, just in case.
You aren’t limited to moving configurations between RAM and NVRAM alone – in fact, you can also save both to a TFTP server. If you reverse the command, you are copying the contents of the startup configuration into RAM, replacing the current running configuration. You can also enter copy run star to achieve the same goal. The example below saves the running configuration settings to the startup configuration.Ĭisco2501#copy running-config startup-config Remember that the copy commands need to be issued from privileged EXEC mode. To save these settings to NVRAM, you copy them to the startup configuration, overwriting what was stored there previously. When you make changes to a router’s configuration by using configure terminal, you are actually changing the settings stored in RAM – the running configuration.
