Working with Configuration Files
This example shows how to configure the software from the file tokyo-confg at IP address 172.16.2.155:
Switch# copy tftp://172.16.2.155/tokyo-confg system:running-config
Configure using tokyo-confg from 172.16.2.155? [confirm] y
Booting tokyo-confg from 172.16.2.155:!!! [OK - 874/16000 bytes]

Uploading the Configuration File By Using TFTP

To upload a configuration file from a switch to a TFTP server for storage, follow these steps:
Step 1 Verify that the TFTP server is properly configured by referring to the “Preparing to Download or Upload
a Configuration File By Using TFTP” section on page B-10.
Step 2 Log into the switch through a Telnet session.
Step 3 Upload the switch configuration to the TFTP server. Specify the IP address or host name of the TFTP
server and the destination filename.
Use one of these privileged EXEC commands:
• copy system:running-config tftp:[[[//location]/directory]/filename]
• copy nvram:startup-config tftp:[[[//location]/directory]/filename]
The file is uploaded to the TFTP server.
This example shows how to upload a configuration file from a switch to a TFTP server:
Switch# copy system:running-config tftp://172.16.2.155/tokyo-confg
Write file tokyo-confg on host 172.16.2.155? [confirm] y

Writing tokyo-confg!!! [OK]
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 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 host name, and domain
is the domain of the switch.
