• 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
• 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.
For more information about LLDP/CDP refer to the
Configuring CDP sections, respectively.
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 switch 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 switch 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
