NOTE: Only the Intel® PRO/1000 family of adapters supports Jumbo frames. |
Jumbo frames are Ethernet frames that are larger than 1518 bytes. You can use jumbo frames to reduce server CPU utilization and improve wire efficiency.
By putting more data in fewer packets, jumbo frames can increase throughput and decrease CPU utilization. However, additional latency may be introduced.
End-to-end network hardware must support this capability otherwise packets will be dropped.
To configure jumbo frames at the switch, consult your network administrator or switch User's Guide.
Supported protocols are limited to IP (TCP, UDP).
Jumbo frames require compatible switch connections that forward jumbo frames. Contact your switch vendor for more information.
When standard sized Ethernet frames are (64 to 1518 Bytes) used, there is no benefit to configuring jumbo frames.
Jumbo frames can be implemented simultaneously with VLANs.

NOTE: The jumbo frames setting at the switch must be set to at least 8 bytes larger than the adapter setting for Windows* operating systems, and at least 22 bytes larger for all other operating systems. |
