Smartport
Error Handling
223 Cisco 500 Series Stackable Managed Switch Administration Guide
12
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 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 Voice VLAN for a description of the voice factory defaults.
