In computer networkingjumbo frames or jumbos are Ethernet frames with more than bytes of payload, the limit set by the IEEE Doing so will cause loss of link.
Advanced Settings for Intel® Ethernet Adapters
Enables the adapter to offload the task of segmenting TCP messages into valid Ethernet frames. Whether this is significant depends on how packets are processed in the host. But, Transmit Descriptors consume system memory.
Enables the adapter to verify the IP checksum on received packets 82567llm compute checksum on transmitted packets.
Jumbo frame - Wikipedia
Log link state event Enables the logging of the following link state changes to the system event log. Large send offload Enables the adapter to offload the task of segmenting TCP messages into valid Ethernet frames. To enter a new network address, type a digit hexadecimal number in the Value box. 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.
Jumbo frames on the network All devices on the network must be configured to handle the maximum size frames sent and received or jumbo frames will be blocked. Devices with limited or no jumbo frame support are listed below. The processing efficiency of the hosts can increase by the ratio of the payloads approximately 6 times improvement in this example. You might choose to increase the number of Transmit Descriptors if you notice a problem with transmit performance.
Please do not enter contact information. Decides whether the adapter or link partner is designated as the master. 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.
Please consider upgrading to the latest version of your browser by clicking one of the following links. Some multi-port devices can be forced to master mode.
Allows the adapter to compute the IP checksum of transmitted packets. Because the adapter hardware can complete data segmentation faster than operating system software, this feature can improve transmission performance.
Most implementations will require non-jumbo user frames to be encapsulated into MPLS frame format which in turn may be encapsulated into a proper Ethernet frame format with EtherType values of 0x and 0x Retrieved from " https: Views Read Edit View history. The issue can also 822567lm in a Forced Slave to Forced Slave mode.
To investigate this issue, click the Link Speed tab and change the speed and duplex settings appropriately. Safari Chrome IE Firefox. Usage considerations Enable Jumbo frames only if devices across the network support them and are configured to use the same frame size.

Changing this setting can improve network performance on certain network and system configurations. Enables the adapter to verify the TCP checksum on received packets and compute checksum on transmitted packets.
Receive Descriptors are data segments that enable the adapter to allocate received packets to memory. Each Ethernet frame must be processed as it mumbo through the network. Transmit Descriptors are data segments that enable the adapter to track transmit packets in the system memory.

Jumbo Frames and Jumbo Packets Notes
If the speed is not set to Auto Negotiation, the driver waits for a short time for link to complete and then reports the link state. This results in poor system performance.
Driver does wait for Auto Negotiation.
