Chapter 22 Configuring Cisco IOS Auto Smartport Macros

Device Visibility Mode

The DC function is enabled on the switch by default. You can disable it by using the no macro auto
monitor global configuration command. The DC feature provides show commands to display the
devices that are connected to the switch. It also provides information about the physical port to which
the device is connected, along with device MAC address and other vendor information. Only directly
connected devices, such as another Layer 2 switch, are classified on nonaccess ports. On access ports
that are connected to hubs, device classification is limited to 32 devices.
When you enable Auto Smartport, the DC is automatically enabled.
