Identifying Smartport Type

If Auto Smartport is globally enabled (in the Properties page) , and at an interface (in the Port Settings page), the switch applies a SmartPort macro to the interface based on the Smartport type of the attaching device. Auto SmartPort derives the SmartPort types of attaching devices based on the CDP and/or LLDP the devices send out.

If, for example, an IP phone is attached to a port, it transmits CDP or LLDP packets that advertise its capabilities. After reception of these CDP and/or LLDP packets, the switch will be able to derive the appropriate SmartPort type for phone and applies the corresponding SmartPort macro to the interface where the IP phone attaches.

Unless Persistent Auto SmartPort is enabled at an interface, the SmartPort type and resulting configuration applied by Auto SmartPort will be removed if the attaching device(s) ages out, links down, reboots, or conflicting capabilities are received. Aging out times are determined by the absence of CDP and/or LLDP advertisements from the device for a specified time period.
