Smartport
Error Handling

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 device 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 page.
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 Voice VLAN for a description of the voice factory defaults.
