There are two ways to apply a Smartport macro by Smartport type to an interface:
• Static Smartport
You manually assign a Smartport type to an interface. The corresponding Smartport
macro is applied to the interface. You can manually assign a Smartport type to an
interface from the Interface Settings page.
• Auto Smartport
When a device is detected from an interface, the Smartport macro, if any, that
corresponds to the Smartport type of the attaching device is automatically applied.
Auto Smartport is enabled by default globally, and at the interface level.
In both cases, the associated anti-macro is run when the Smartport type is removed from the
interface, and the anti-macro runs in exactly the same manner, removing all of the interface
configuration.
Auto Smartport
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 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.
