If multiple devices are connected to the switch through one interface, Auto
Smartport will consider 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.

Configuring LLDP
and

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 will remain on
the interface even after the attaching device ages out, the interface goes down,
and the switch is rebooted (assuming the configuration is being saved). The
SmartPort type and the configuration of the interface are not changed unless Auto
Smartport detects an attaching device with a different Smartport. 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
switch is rebooted. Enabling Persistent Status on an interface eliminates the
device detection delay that otherwise will occur.
NOTE
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 are saved to the startup configuration file.
