Working with Software Images
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 want to use for the FTP
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 using the ip ftp username
username global configuration command. This new name will be used during all archive operations.
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 hat operation only.
•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.
For more information, see the documentation for your FTP server.
