Multiple Devices Attached to the Port

The switch derives the SmartPort type of an attaching device based on the capabilities the device advertises in its CDP and/or LLDP packets.

If an interface is attached with more than one device, possibly though a hub, Auto Smartport will take all the capabilities advertisement it receives from the interface into consideration when assigning the Smartport type for the interface. The assignment is based on the following algorithm:
