Special Smartport Types
There are two special Smartport types; default and unknown. These two types are not
associated with macros, but they exist to signify the state of the interface regarding Smartport.
The following describe these special Smartport types:
• Default
An interface that does not (yet) have a Smartport type assigned to it has the Default
Smartport status.
If Auto Smartport assigns a Smartport type to an interface and the interface is not
configured to be Auto Smartport Persistent, then its Smartport type is re-initialized to
Default in the following cases:
- A link down/up operation is performed on the interface.
- The device is restarted.
- All devices attached to the interface have aged out, which is defined as the absence
of CDP and/or LLDP advertisement from the device for a specified time period.

Throughout this section, the term "aged out" is used to describe the LLDP and CDP messages

or LLDP messages are received on the interface before both TTLs of the most recent CDP and
LLDP packets decrease to 0, then the anti-macro is run, and the Smartport type returns to
default.
