# Jumbo Frames

| NOTE: Jumbo Frames are supported at 1000 Mbps only. Using Jumbo Frames at 10 or 100 Mbps may result in poor performance or loss of link.

Jumbo frames are Ethernet frames that are larger than 1518 bytes. You can use Jumbo Frames to reduce server CPU utilization and increase throughput. However, additional latency may be introduced.

| NOTE: End-to-end network hardware must support this capability; otherwise, packets will be dropped.

Jumbo Frames can be implemented simultaneously with VLANs and teaming.

To configure Jumbo Frames at the switch, consult your network administrator or switch user's guide.

Restrictions:

- Jumbo frames are not supported in multi-vendor team configurations.

- 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 (64 to 1518 bytes) are used, there is no benefit to configuring Jumbo Frames.

- The Jumbo Frames setting on 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.
