Cisco Cisco IOS Software Release 12.2(35)SE Notas de publicación

When creating a switch cluster or adding a switch to a cluster, follow these guidelines:

When you create a switch cluster, we recommend configuring the highest-end switch in your cluster 
as the command switch.

If you are managing the cluster through Network Assistant, the switch with the latest software 
should be the command switch, unless your command switch is running Cisco IOS Release 
12.1(19)EA1 or later. 

The standby command switch must be the same type as the command switch. For example, if the 
command switch is a Catalyst 3750 switch, all standby command switches must be Catalyst 3750 
switches. 

For additional information about clustering, see Getting Started with Cisco Network Assistant and 
Release Notes for Cisco Network Assistant (not orderable but available on Cisco.com), the software 
configuration guide, and the command reference.

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.
