Noteįor adapters to benefit from this feature, link partners must support flow control frames. You can configure Large Send Offload separately for IPv4 and IPv6. The adapter also uses fewer CPU resources. When configuring Jumbo frames on a switch, set the frame size 4 bytes higher for CRC, plus 4 bytes if using VLANs or QoS packet tagging.Įnables the adapter to offload the task of segmenting TCP messages into valid Ethernet frames.īecause the adapter hardware can complete data segmentation faster than operating system software, this feature can improve transmission performance.Using Jumbo frames at 10 or 100 Mbps can result in poor performance or loss of link.Intel® adapters do not include header information in the frame size. Some devices include the header information in the frame size while others do not.

When setting up Jumbo Frames on other network devices, be aware that different network devices calculate Jumbo Frame sizes differently. Enable Jumbo frames only if devices across the network support them and are configured to use the same frame size.Jumbo frames are larger than standard Ethernet frames, which are 1.5k in size. 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. Changing this setting can cause a momentary loss of connectivity.Įnables or disables Jumbo frame capability. The issue can also occur in a Forced Slave to Forced Slave mode. If forced to master mode, the device can either disconnect or downshift to a 100-Mbps link. Some multi-port devices can be forced to master mode. The other device is designated as the slave.Ĭhanging the setting can improve link quality with certain link partners. For the latest settings information, go to the Advanced tab in Intel PROSET for Windows Device Manager.ĭecides whether the adapter or link partner is designated as the master. Most advanced configuration settings and definitions are described in the table below. If a configuration setting is not displayed, it's not available for your device or for your Windows* version.

Intel® PROSet for Windows Device Manager includes an Advanced tab with Settings options and definitions: Intel® Advanced Network Services (Intel® ANS) isn't supported on In-box drivers. Intel® PROSet for Windows* Device Manager is a selectable component when you install generic driver and software packages from the Download Center.
