Cisco Cisco IOS Software Release 12.2(35)SE

switch cannot recognize the member switch, and the Front Panel view displays it as an unknown device. 
You cannot configure any parameters or generate a report through CMS for that member; instead, you 
must launch the Device Manager application to configure and to obtain reports for that member.

If you have a cluster with switches that are running different versions of Cisco IOS software, features 
added on the latest release might not be reflected on switches running the older releases. For example, 
if you start CMS on a Catalyst 2900 XL switch running Cisco IOS Release 11.2(8)SA6, the windows 
and functionality can be different from a switch running Cisco IOS Release 12.0(5)WC(1) or later.

Some early Cisco IOS releases do not support clustering. 

For more information about clustering and CMS, refer to the software configuration guide. 

These are the procedures for downloading software. Before downloading software, read this section for 
important information:

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.

For Catalyst 3750 and 3560 switches, although the show version output always shows the software 
image running on the switch, the model name shown at the end of this display is the factory configuration 
(standard multilayer image [SMI] or enhanced multilayer image [EMI]) and does not change if you 
upgrade the software image.

You also can 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 both the Cisco IOS image file and the files needed for CMS. You must use the 
combined tar file to upgrade the switch through CMS. To upgrade the switch through the command-line 
interface (CLI), use the tar file and the archive download-sw privileged EXEC command.
