When the SP uses the network interface for firmware updates

An SP firmware update that is triggered from Data ONTAP with the SP running version 1.5, 2.5, 3.1, or later supports using an IP-based file transfer mechanism over the SP network interface.

An SP firmware update over the network interface is faster than an update over the serial interface. It reduces the maintenance window during which the SP firmware is being updated, and it is also nondisruptive to Data ONTAP operation. The SP versions that support this capability are included with Data ONTAP 8.3 and later. They are also available on the NetApp Support Site and can be installed on controllers that are running a compatible version of Data ONTAP.

When you are running SP version 1.5, 2.5, 3.1, or later, the following firmware upgrade behaviors apply:

Regardless of the SP version you are running, an SP firmware update triggered from the SP CLI always uses the SP network interface for the update.
