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.
• Unknown
If a Smartport macro is applied to an interface and an error occurs, the interface is assigned the
Unknown status. In this case, the Smartport and Auto Smartport features do not function on the
interface until you correct the error and applies the Reset action (performed in the Interface Settings
pages) that resets the Smartport status.

NOTE
Smartport Macros
A Smartport macro is a script that configure an interface appropriately for a particular network device.
Smartport macros should not be confused with global macros. Global macros configure the device globally,
however, the scope of a Smartport macro is limited to the interface on which it is applied.
The macro source may be found by clicking the View Macro Source button on the Smartport Type
Settings page.

Common Smartport Tasks
Throughout this section, the term "aged out" is used to describe the LLDP and CDP
messages via their TTL. If Auto Smartport is enabled, and persistent status is
disabled, and no more CDP 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.
