Smartports Error Handling 10 For more information about LLDP/CDP refer to the Configuring LLDP and Configuring CDP sections, respectively. 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 Voice VLAN for a description of the voice factory defaults. Cisco Small Business 200 Series Smart Switch Administration Guide 129
