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 Smartport 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:
