Cisco Systems 3560 Manual De Usuario

You can copy (upload) configuration files from the switch to a file server by using TFTP, FTP, or RCP. 
You might perform this task to back up a current configuration file to a server before changing its 
contents so that you can later restore the original configuration file from the server. 

The protocol you use depends on which type of server you are using. The FTP and RCP transport 
mechanisms provide faster performance and more reliable delivery of data than TFTP. These 
improvements are possible because FTP and RCP are built on and use the TCP/IP stack, which is 
connection-oriented.

These sections contain this configuration information:

Creating configuration files can aid in your switch configuration. Configuration files can contain some 
or all of the commands needed to configure one or more switches. For example, you might want to 
download the same configuration file to several switches that have the same hardware configuration.

Use these guidelines when creating a configuration file:

We recommend that you connect through the console port for the initial configuration of the switch. 
If you are accessing the switch through a network connection instead of through a direct connection 
to the console port, keep in mind that some configuration changes (such as changing the switch IP 
address or disabling ports) can cause a loss of connectivity to the switch.

If no password has been set on the switch, we recommend that you set one by using the enable secret 
secret-password global configuration command.

The copy {ftp: | rcp: | tftp:} system:running-config privileged EXEC command loads the 
configuration files on the switch as if you were entering the commands at the command line. The switch 
does not erase the existing running configuration before adding the commands. If a command in the 
copied configuration file replaces a command in the existing configuration file, the existing command 
is erased. 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 is used. However, 
some commands in the existing configuration might not be replaced or negated. In this case, the resulting 
configuration file is a mixture of the existing configuration file and the copied configuration file, with 
the copied configuration file having precedence. 

 

 
To restore a configuration file to an exact copy of a file stored on a server, copy the configuration file 
directly to the startup configuration (by using the copy {ftp: | rcp: | tftp:} nvram:startup-config 
privileged EXEC command), and reload the switch.
