Optimize Ports through Smartports Port Roles
These are the concepts and procedures for using Smartports port roles:

What Are Smartports Port Roles
Tip Use Smartports port roles immediately after switch initial setup. The switch ports
are then correctly configured before they are connected to devices.
The Smartports port roles are Cisco-recommended configurations for the switch
ports. These configurations (referred to as port roles) optimize the switch
connections and ensure security and transmission quality and reliability to traffic
from the switch ports. They also prevent many problems caused by port
misconfigurations.
The port roles ( Table 3-1 ) are based on the type of devices to be connected to the
switch ports. For example, the Desktop port role is specifically for switch ports
that will be connected to desktop and laptop PCs.
Figure 3-1 shows different types of devices connected to the Catalyst Express
switches. Through Smartports port roles, each connection from the switches is
optimized for its attached device.
Figure 3-2 is an example of the Smartports window on the device manager. It
shows port roles applied to the ports. Only port 22 does not have a port role
applied to it.
