To find out if the network adaptor on your PC can support Jumbo Frames perform the following steps:
- Open up your network card properties in Device Manager, and select the Advanced tab.
- Under the property list box, select Jumbo Frames. If this is not present, you most likely do not have the ability to use Jumbo Frames on the card.
- After selecting Jumbo Frames, you should see a pull-down menu to the right specifying the size of packets. Select a packet size of 9014. Your PC will now be able to receive the large Jumbo Frames packets.
If any trouble is encountered during this process, please reference How to Acquire from GigE Vision Cameras with Vision Acquisition Software
In general, NI hardware support for jumbo frames is determined by three factors: operating system, the network adapter chipset and the network adapter driver. If you are unsure what operating system your Real-Time controller is running, please see Real-Time Controllers and Real-Time Operating System Compatibility
The first requirement for jumbo frames is that the network adapter be a Gigabit ethernet port. Any non-Gigabit ports will not support jumbo frames regardless of operating system or driver. Additionally, all hardware on a particular network must support Jumbo frames in order for the data to be transferred in that manner.
In general, National Instruments hardware does not support changing the MTU at this time (this includes not supporting Jumbo Frames). Most PXI Controllers and ENET devices do not have this capability. However, Ethernet cDAQ-918x supports jumbo frames with MTU sizes up to 9000*. In addition to the Ethernet cDAQ, some National Instruments Image Acquisition (IMAQ) devices support MTU customization for high data rates. You should check into these devices on a case-by-case basis to determine Jumbo Frame support. Any National Instruments card that supports the GigE standard will support Jumbo Frames.
