Working with Configuration Files
Copying Configuration Files By Using FTP
You can copy configuration files to or from an FTP server.
The FTP protocol requires a client to send a remote username and password on each FTP request to a
server. When you copy a configuration file from the switch to a server by using FTP, the Cisco IOS
software sends the first valid username in this list:
• The username specified in the copy command if a username is specified.
•
The username set by the ip ftp username username global configuration command if the command
is configured.
• Anonymous.
The switch sends the first valid password in this list:
• The password specified in the copy command if a password is specified.
•
The password set by the ip ftp password password global configuration command if the command
is configured.
• The switch forms a password named username@switchname.domain . The variable username is the
username associated with the current session, switchname is the configured hostname, and domain
is the domain of the switch.
The username and password must be associated with an account on the FTP server. If you are writing to
the server, the FTP server must be properly configured to accept your FTP write request.
Use the ip ftp username and ip ftp password commands to specify a username and password for all
copies. Include the username in the copy command if you want to specify only a username for that copy
operation.
If the server has a directory structure, the configuration file is written to or copied from the directory
associated with the username on the server. For example, if the configuration file resides in the home
directory of a user on the server, specify that user's name as the remote username.
For more information, see the documentation for your FTP server.

Preparing to Download or Upload a Configuration File By Using FTP
Before you begin downloading or uploading a configuration file by using FTP, do these tasks:
•
Ensure that the switch has a route to the FTP server. The switch and the FTP server must be in the
same subnetwork if you do not have a router to route traffic between subnets. Check connectivity to
the FTP server by using the
ping command.
