Enabling jumbo frames
Standardized Ethernet frames have a size of 1518 bytes. Ethernet frames that are larger than 1518 bytes
are referred to as jumbo frames. Jumbo frames are used for transferring large data quantities. Jumbo frames
are useful for certain applications, e.g. video cameras.
The Ethernet interfaces (X000, X001) support jumbo frames only if the original Intel® driver is installed.
Requirements:
• The original Intel® driver can be downloaded from
https://downloadcenter.intel.com
.
• Install the original Intel® driver. Note that this will delete the real-time capable driver from Beckhoff.
• Check whether the peripheral devices support jumbo frames.
Jumbo frames are activated as follows:
1. Under
Start > Control Panel > Hardware and Sound
click on
Device Manager
.
2. Double-click on the interface and then on the
Advanced
tab.
3. Under
Settings
click on Jumbo Packet, under
Value
select the option 4088 bytes or 9014 bytes.
ð
You have successfully activated jumbo frames, and you can now transfer larger data quantities.
