Working with Software Images
• The password set by the ip ftp password password global configuration command if the command
is configured.
• The access point forms a password named username@apname.domain. The variable username is
the username associated with the current session, apname is the configured host name, and domain
is the domain of the access point.
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 directory associated
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, perform these tasks:
• Ensure that the access point has a route to the FTP server. The access point and the FTP server must
be in the same subnetwork if you do not have a router to route traffic between subnets. Verify
connectivity to the FTP server by using the ping command.
• If you are accessing the access point through 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 username 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 access point 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 that 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 access point.
For more information, refer to the documentation for your FTP server.
Downloading an Image File by Using FTP
You can download a new image file and overwrite the current image or keep the current image.
Caution For the download and upload algorithms to operate properly, do not rename image directories.
Beginning in privileged EXEC mode, follow Steps 1 through 7 to download a new image from an FTP
server and overwrite the existing image. To keep the current image, skip Step 7.
Command Purpose
Step 1
Verify that the FTP server is properly configured by referring
to the “Preparing to Download or Upload an Image File by
Using FTP” section on page 20-23.
Step 2
Log into the access point through a Telnet session.
