Multiple Devices Attached to the Port The switch derives the Smartport type of a connected device via the capabilities the device advertises in its CDP and/or LLDP packets. If multiple devices are connected to the switch through one interface, Auto Smartport considers each capability advertisement it receives through that interface in order to assign the correct Smartport type. The assignment is based on the following algorithm: • If all devices on an interface advertise the same capability (there is no conflict) the matching Smartport type is applied to the interface. • If one of the devices is a switch, the Switch Smartport type is used. • If one of the devices is an AP, the Wireless Access Point Smartport type is used. • If one of the devices is an IP phone and another device is a host, the ip_phone_desktop Smartport type is used. • If one of the devices is an IP phone desktop and the other is an IP phone or host, the ip_phone_desktop Smartport type is used. • In all other cases the default Smartport type is used.
