Cisco Cisco IOS Software Release 15.2(3)E 發佈版本通知

When you create a switch cluster or add a switch to a cluster, follow these guidelines:

We recommend that you configure 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. 

The standby command switch must be the same type as the command switch. For example, if the 
command switch is a Catalyst 2960-X switch, all standby command switches must be 
Catalyst 2960-X switches. 

For additional information about clustering, see Getting Started with Cisco Network Assistant, Release 
Notes for Cisco Network Assistant, the Cisco-enhanced EtherSwitch service module documentation, the 
software configuration guide, and the command reference.

For Cisco IOS Release 15.2(5)E, CNA support is available on release version 5.8.9 and later.

The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release 
number. The files necessary for web management are contained in a subdirectory. 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. 

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 and does not change if you upgrade 
the software license.

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.
