Wait for link Decides if the driver waits for Auto Negotiation to be successful before reporting the link state. When you use a higher ITR setting, the interrupt rate is lower, and the result is better system performance. Some multi-port devices can be forced to master mode. Therefore, you might find that different values must be configured in equipment from different vendors to make the settings match. Note For adapters to benefit from this feature, link partners must support flow control frames. This also minimizes the overhead byte count and reduces the number of frames needing to be processed. Consequently, additional mechanisms have been developed to improve error detection on higher network layers.

Using jumbo frames at 10 or Mbps is not supported and may result in poor performance or loss of link. Requiem for Jumbo Frames”.

Changing this setting may cause a momentary loss of connectivity. Can be configured separately for IPv4 and IPv6.

Doing so may cause the system to reboot under normal to heavy receive traffic. This article needs rrame citations for verification. Retrieved April 28, Changing this setting can improve network performance on certain network and system configurations. The switch may be configured for a larger size as long as the setting is at least 22 bytes higher. As the nodes in general use reciprocating logic to handle the packets, the total number of machine cycles spent processing packet headers decreases as the average MSS of the packets increases given a certain total amount of data transmitted.


Jumbo frame – Wikipedia

The frame size used by an end-to-end connection is typically limited by the lowest frame size in intermediate links. The main factor involved with an increase in the maximum segment size MSS is an increase in the available memory buffer size in all of the intervening persistence mechanisms along the path.

Jumbo frames are larger than standard Ethernet frames, which are 1. Jumbo frames or byte payload frames have the potential to reduce overheads and CPU cycles. Automatically set to On or Off depending on speed and adapter type when the driver is installed. To investigate this issue, click the Link Speed tab and change the speed and duplex settings appropriately. If MACSec is enabled on a platform containing either part, you will not be able to enable jumbo frames on the connection.

Enables the adapter to verify the TCP checksum on received packets and compute checksum on transmitted packets. Jumbo frames jumbo packets Enables or disables Jumbo frame capability. Enables adapters to generate or respond to flow control frames, which help regulate network traffic.

One of the major impediments toward the adoption of jumbo frames has been the inability to upgrade existing Ethernet infrastructure that would be needed to avoid a reduction in the ability to detect errors.

When this setting is disabled, the adapter cannot tag outgoing packets with Many other vendors also adopted the size; however, jumbo frames did not become part of the official IEEE When this feature is enabled, the network adapter dynamically adapts to network traffic conditions.


For example, in the address 0YA, Y cannot be an odd number. But, Transmit Descriptors consume system memory.

Allows the adapter to framw the IP checksum of transmitted packets. To enter a new network address, type a digit hexadecimal number in the Value box. Options Off The adapter cannot send or receive 8256l7m control frames.

Performance options – Flow control Enables adapters to generate or respond to flow control frames, which help regulate network traffic. 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 When this feature is enabled, tagged packets use the queue settings defined by the operating system Priority Level Definition.

Jumbo Frames and Jumbo Packets Notes

Performance options – Transmit Descriptors or Transmit buffers. Most advanced configuration settings and definitions are described in the table below. This relationship becomes increasingly important frae average network line bit rate increases to 10 gigabits per second, and above. Note A higher ITR also means the driver has more latency in handling packets.
