Working with Software Images
Preparing to Download or Upload an Image File By Using FTP
You can copy images files to or from an FTP server.
The FTP protocol requires a client to send a remote userna me a nd passwor d on ea ch FTP re quest to a
server. When you copy an image 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 archive download-sw or archive upload-sw privileged EXEC
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 archive download-sw or archive upload-sw privileged EXEC
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 the FTP write request from you.
Use the ip ftp username and ip ftp password commands to specify a username and password for all
copies. Include the username in the archive download-sw or archive upload-sw privileged EXEC
command if you want to specify a username only for that operation.
If the server has a directory structure, the image file is written to or copied from the directo ry associa ted
with the username on the server. For example, if the image file resides in the home directory of a user
on the server, specify that user's name as the remote username.
Before you begin downloading or uploading an image 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 co nnectivity to
the FTP server by using the ping command.
•If you are accessing the switch through the console or a Telnet session and you do not have a valid
username, make sure that the current FTP username is the one that you wa nt to use for t he FT P
download. You can enter the show users privileged EXEC command to view the valid username. If
you do not want to use this username, create a new FTP userna me by usin g th e ip ftp username
username global configuration command. This new name will be used during all arch iv e ope rations.
The new username is stored in NVRAM. If you are accessing the switch through a Telnet session
and you have a valid username, this username is used, and you do not need to set the FTP username.
Include the username in the archive download-sw or archive upload-sw privileged EXEC
command if you want to specify a username for t ha t op er ati on on ly.
•When you upload an image file to the FTP server, it must be properly configured to accept the write
request from the user on the switch.
