82567LM JUMBO FRAME DRIVER

Some Fast Ethernet switches and Fast Ethernet network interface cards can also support jumbo frames. Retrieved from ” https: Support of Castagnoli CRC polynomial within a general purpose transport designed to handle data chunks, and within a TCP transport designed to carry SCSI data, both provide improved error detection rates despite the use of jumbo frames where increase of the Ethernet MTU would have otherwise resulted in a significant reduction in error detection. Jumbo frames jumbo packets Enables or disables Jumbo frame capability. Enable jumbo frames only if devices across the network support them and are configured to use the same frame size. Compensates for excessive Ethernet packet collisions by controlling back-to-back timing. This setting has no effect if your system has only one processing unit.

Advanced Settings for Intel® Ethernet Adapters

Please help improve this article by adding citations to reliable sources. When an event occurs, the adapter generates an interrupt, which allows the driver to handle the packet.

If you require a response, contact support.

Large send offload Enables the adapter to offload the task of segmenting TCP messages into valid Ethernet frames. If large packets make up the majority of traffic and more latency can be tolerated, Jumbo frames can reduce CPU utilization and improve wire efficiency. Jumbp results in poor system performance.

Enables the adapter to verify the TCP checksum on received packets and compute checksum on transmitted packets. This page was last edited on 4 Decemberat This setting grame no effect if your system has only one processing unit.

Whether this is significant depends on how packets are processed in the host. The relative scalability of network data throughput as a function of packet transfer rates is related in a complex manner [17] to payload size per packet. Changing this setting may cause a momentary loss of connectivity.

The adapter also uses fewer CPU resources. Enable jumbo frames only if devices across the network support them and are configured to use the same frame size. With this setting, the CPU utilization may be higher. The browser version you are using is not recommended for this site.

Network architecture Packets information technology. Retrieved from ” https: Usage considerations Enable Jumbo frames only if devices across the network support them and are configured to use the same frame size.

Allows the adapter to compute the IP checksum of transmitted packets. Note For adapters to benefit from this feature, link partners must support flow control frames. Support of Castagnoli CRC polynomial within a general purpose transport designed to handle data chunks, and within a TCP transport designed to carry SCSI data, both provide improved error detection rates despite the use of jumbo frames where increase of the Ethernet MTU would have otherwise resulted in a significant reduction in error detection.

The following devices have this limitation:. Most advanced configuration settings and definitions are described in the table below. Increasing the number of Transmit Descriptors can enhance transmit performance.

Larger frames are more likely to suffer undetected errors with the simple CRC32 error detection used in Ethernet frames — a larger amount of data increases the probability that several errors cancel each other out. Therefore, you might find that different values must be configured in equipment from different vendors to make the settings match.

Enables adapters to generate or respond to flow control frames, which help regulate network traffic. If MACSec is enabled on a platform containing either part, you will not be able to enable jumbo frames on the connection. Sets the number of buffers used by the driver when copying data to the protocol memory.

Decides whether the adapter or link partner is designated as the master. Please do not enter contact information. Many other vendors also adopted the size; however, jumbo frames did not become part of the official IEEE Intel adapters do not include header information in the frame size.

Some Fast Ethernet switches and Fast Ethernet network interface cards can also support jumbo frames. The following devices have this limitation:
