Finding the Software Version and Feature Set
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 system board
flash device (flash:).
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.
Deciding Which Files to Use
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 device
manager. You must use the combined tar file to upgrade the switch through the device manager. To
upgrade the switch through the command-line interface (CLI), use the tar file and the
archive
download-sw
privileged EXEC command.

If you wish to use Device Manager to upgrade the switch from Cisco IOS Release 12.2(35)SE through
Cisco IOS Release 12.2(40)SE1 (the LAN Base image) to Cisco IOS Release 12.2(50)SE or later (the IP
base image), you must first upgrade to Cisco IOS Release 12.2(40)SE2.
