Cisco Cisco IOS Software Release 12.2(58)SE

For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory 
and image names are case sensitive.

This example shows how to download an image from a TFTP server at 198.30.20.19 and to overwrite 
the image on the switch:

Switch# archive download-sw /overwrite tftp://198.30.20.19/image-name.tar

You can also download the image file from the TFTP server to the switch and keep the current image by 
replacing the /overwrite option with the /leave-old-sw option.

For recovery procedures, see the “Troubleshooting” chapter in the software configuration guide for 
this release.
