Working with Software Images
tar File Format of Images on a Server or Cisco.com
Software images located on a server or downloaded from Cisco.com are provided in a tar file format, 
which contains these files:
  •
An info file, which serves as a table of contents for the tar file
  •
One or more subdirectories containing other images and files, such as Cisco IOS images
This example shows some of the information contained in the info file. 
 provides additional 
details about this information:
version_suffix: image-name 
version_directory: image-name 
image_system_type_id: 0x00000000 
image_name: image-name .bin 
ios_image_file_size: 4526592 
total_image_file_size: 4526592 
image_feature: LAYER_2|MIN_DRAM_MEG=64 
image_family: family
stacking_number: 1.11 
board_ids: 0x00000029

Note
Disregard the stacking_number field. It does not apply to the switch.
Copying Image Files By Using TFTP
You can download a switch image from a TFTP server or upload the image from the switch to a TFTP 
server.
You download a switch image file from a server to upgrade the switch software. You can overwrite the 
current image with the new one or keep the current image after a download.
You upload a switch image file to a server for backup purposes; this uploaded image can be used for 
future downloads to the same or another switch of the same type.
