Cisco Systems SG50028PK9NA Error Handling, Default Configuration

Smartport
Error Handling
Cisco Small Business 200, 300 and 500 Series Managed Switch Administration Guide (Internal Version) 167
11
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 VL AN for a description of the voice factory defaults.
