Auto Smartport

Cisco Small Business 300 Series Managed Switch Administration Guide 

152

 

In order for Auto Smartport to automatically assign Smartport types to interfaces, 
the Auto Smartport feature must be enabled globally and on the relevant 
interfaces which Auto Smartport should be allowed to configure. By default, Auto 
Smartport is enabled and allowed to configure all interfaces. The Smartport type 
assigned to each interface is determined by the CDP and LLDP packets received 
on the each interface respectively.

•

If multiple devices are attached to an interface, a configuration profile that is 
appropriate for all of the devices is applied to the interface if possible. 

•

If a device is aged out (no longer receiving advertisements from other 
devices), the interface configuration is changed according to its Persistent 
Status. If the Persistent Status is enabled, the interface configuration is 
retained. If not, the Smartport Type reverts to Default.

Auto Smartport can be enabled globally in the Properties page in the following 
ways:

•

Enabled—This manually enables Auto Smartport and places it into 
operation immediately.

•

Enable by Auto Voice VLAN—This enables Auto Smartport to operate if 
Auto Voice VLAN is enabled and in operation. Enable by Auto Voice VLAN is 
the default.

In addition to enabling Auto Smartport globally, you must enable Auto Smartport at 
the desired interface as well. By default, Auto Smartport is enabled at all the 
interfaces.

See 

 for more information on enabling Auto Voice VLAN

If Auto Smartport is globally enabled (in the Properties page), and at an interface 
(in the Interface Settings page), the device applies a Smartport macro to the 
interface based on the Smartport type of the attaching device. Auto Smartport 
derives the Smartport types of attaching devices based on the CDP and/or LLDP 
the devices advertise.
