If multiple devices are connected to the device 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.

Persistent Auto Smartport Interface
If the Persistent status of an interface is enabled, its Smartport type and the configuration that
is already applied dynamically by Auto Smartport remains on the interface even after the
attaching device ages out, the interface goes down, and the device is rebooted (assuming the
configuration was saved). The Smartport type and the configuration of the interface are not
changed unless Auto Smartport detects an attaching device with a different Smartport type. If
the Persistent status of an interface is disabled, the interface reverts to the default Smartport
type when the attaching device to it ages out, the interface goes down, or the device is
rebooted. Enabling Persistent status on an interface eliminates the device detection delay that
otherwise occurs.
The persistence of the Smartport types applied to the interfaces are effective between reboots
only if the running configuration with the Smartport type applied at the interfaces is saved to
the startup configuration file.
When a smart port macro fails to apply to an interface, you can examine the point of the failure
