What Factors Should Be Considered When Managing Files?
Uploading and Downloading Files
To use TFTP, SFTP, SCP, or FTP for file management, you must provide the
IP address of the remote system that is running the appropriate server (TFTP,
SFTP, SCP or FTP). Make sure there is a route from the switch to the remote
system. The ping command in the CLI can be used to verify that a route
exists between the switch and the remote system.
If you are downloading a file from the remote system to the switch, be sure to
provide the correct path to the file and the correct file name.
Managing Images
When you download a new image to the switch, it overwrites the backup
image, if it exists. To use the new image, it must be activated and reloaded on
the switch. The image that was previously the active image becomes the
backup image after the switch reloads. If the switch is upgraded to a newer
image and the image is found to be incompatible with the network, the
switch can revert to the original image.
If a new image is activated and reloaded on the switch, and the switch is
unable to complete the boot process due to a corrupt image or other problem,
the boot menu can be used to activate the backup image. The administrator
must connect to the switch through the console port to access the boot
menu. The image files may contain firmware for the PHY processors on the
NOTE: The use of SFTP, SCP or HTTPS may require RSA/DSA keys to be
generated prior to use.
