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.
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 is saved to the startup configuration file.
Error Handling
When a smart port macro fails to apply to an interface, you can examine the point
of the failure in the
Interface Settings
page and reset the port and reapply the
macro after the error is corrected from the
Interface Settings
and
Interface
Settings Edit
pages.
Default Configuration
Smartport is always available. By default, Auto Smartport is enabled by Auto
Voice VLAN, relies on both CDP and LLDP to detect attaching device's Smartport
type, and detects Smartport type IP phone, IP phone + Desktop, Switch, and
Wireless Access Point.
See the
Voice VLAN
section for a description of the voice factory defaults.
