Cisco Cisco IOS Software Release 15.2(3)E

The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. A subdirectory contains the 
files needed for web management. The image is stored on the compact flash memory card.

You can use the show version privileged EXEC command to see the software version that is running on your switch. The 
second line of the display shows the version.

You can also use the dir filesystem: privileged EXEC command to see the directory names of other software images that you 
might have stored in flash memory.

The upgrade procedures in these release notes describe how to perform the upgrade by using a combined tar file. This file 
contains the Cisco IOS image file and the files needed for the embedded Express Setup. You must use the combined tar file to 
upgrade the switch through Express Setup. To upgrade the switch through the CLI, use the tar file and the archive 
download-sw privileged EXEC command.

Before upgrading your switch software, make sure that you have archived copies of the current
Cisco IOS release and the Cisco IOS release to which you are upgrading. You should keep these archived images until you have 
upgraded all devices in the network to the new Cisco IOS image and until you have verified that the new Cisco IOS image 
works properly in your network.

Cisco routinely removes old Cisco IOS versions from Cisco.com. See Product Bulletin 2863 for more information:

You can copy the bin software image file on the flash memory to the appropriate TFTP directory on a host by using the copy 
flash: tftp: privileged EXEC command. 

Although you can copy any file on the flash memory to the TFTP server, it is time-consuming to copy 
all of the HTML files in the tar file. We recommend that you download the tar file from Cisco.com and 
archive it on an internal host in your network.

You can also configure the switch as a TFTP server to copy files from one switch to another without using an external TFTP 
server by using the tftp-server global configuration command. For more information about the tftp-server command, see the 
“Basic File Transfer Services Commands” section of the Cisco IOS Configuration Fundamentals Command Reference, Release
