about the Cisco IOS Software release process, see Product Bulletin #537.
Cisco continues its commitment to providing industry-leading usability with the following changes.
Smart Ports, which first shipped in Cisco IOS Software Release 12.1(19)EA1, have been enhanced to include several default connection types that
use Cisco recommended configuration settings. These default types can be quickly and easily assigned to ports using Cluster Management Suite
(CMS), the embedded network management tool included with every fixed configuration switch.
CMS now supports the configuration of Auto-MDIX (medium-dependent interface crossover), which allows different types of cables to connect
networking devices. CMS can enable or disable this feature.
The CMS plug-in is a simple installation program that configures the management station with the correct run-time software to support CMS.
In addition to existing support on Microsoft Windows platforms, CMS plug-in is supported on Sun Microsystems Solaris operating system.
