NOTE
Cisco 500 Series Stackable Managed Switch Administration Guide
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.
Enabling Auto Smartport
Auto Smartport can be enabled globally in the
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 Voice VLAN for more information on enabling Auto Voice VLAN
