Image Location On The Switch; Tar File Format Of Images On A Server Or Cisco.com - Cisco 3750G - Catalyst Integrated Wireless LAN Controller Configuration Manual

Working with Software Images
You upload a switch image file to a TFTP, FTP, or RCP server for backup purposes. You can use this
uploaded image for future downloads to the same switch or to another of the same type.
The protocol that you use depends on which type of server you are using. The FTP and RCP transport
mechanisms provide faster performance and more reliable delivery of data than TFTP. These
improvements are possible because FTP and RCP are built on and use the TCP/IP stack, which is
connection-oriented.

Image Location on the Switch

The Cisco IOS image is stored as a .bin file in a directory that shows the version number. A subdirectory

(flash:).
You can use the show version privileged EXEC command to see the software version that is currently
running on your switch. In the display, check the line that begins with
shows the directory name in flash memory where the image is stored.
You can also use the dir filesystem: privileged EXEC command to see the directory names of other
software images that might be stored in flash memory. Beginning with Cisco IOS release 12.2(35)SE,
the archive download-sw /directory privileged EXEC command allows you to specify a directory one
time followed by a tar file or list of tar files to be downloaded instead of specifying complete paths with
each tar file. For example, you can enter archive download-sw /directory tftp://10.1.1.10/
c3750-ipservices-tar.122-35.SE.tar c3750-ipbase-tar.122-35.SE.tar.
