6.1.2. Uploading and Downloading Files
To use FTP, TFTP, SFTP, or SCP for file management, you must provide the IP address of the remote system
that is running the appropriate server (FTP, TFTP, SFTP, or SCP). Make sure there is a route from the switch to
the remote system. You can use the
ping
command from the CLI to verify that a route exists between the
switch and the remote system.
If you are copying a file from the remote system to the switch, be sure to provide the correct path to the file
(if the file is
not in the root directory) and the correct file name.
6.1.3. Managing Switch Software (Images)
The switch can maintain two software images: the active image and the backup image. When you copy a
new image from a remote system to the switch, you can specify whether to save it as the active or backup
image. The downloaded image overwrites the image that you specify. If you save the new image as the
active image, the switch continues to operate using the current (old) image until you reload the switch.
Once the switch reboots, it loads with the new image. If you download the new image as the backup image,
the file overwrites the current backup image, if it exists. To load the switch with the backup image, you must
first set it as the active image and then reload the switch. The image that was previously the active image
becomes the backup image after the switch reloads.
If you activate a new image and reload the switch, and the switch is unable to complete the boot process
due to a corrupt image or other problem, you can use the boot menu to activate the backup image. You
must be connected to the switch through the console port to access the boot menu.
To create a backup copy of the firmware on the switch, copy the active image to the backup image. You can
also copy an image to a file on a remote server.
6.1.4. Managing Configuration Files
Configuration files contain the CLI commands that change the switch from its default configuration. The
switch can maintain three separate configuration files: startup-config, running-config, and backup-config.
The switch loads the startup-config file when the switch boots. Any configuration changes that take place
after the boot process completes are written to the running-config file. The backup-config file does not exist
until you explicitly create one by copying an existing configuration file to the backup-config file or
downloading a backup-config file to the switch.
You can also create configuration scripts, which are text files that contains CLI commands.
When you apply (run) a configuration script on the switch, the commands in the script are executed in the
order in which they are written as if you were typing them into the CLI. The commands that are executed in
the configuration script are added to the running-config file.
You might upload a configuration file from the switch to a remote server for the following reasons:
