The settings listed in the "Advanced" tab enable you to customize how the adapter handles QoS packet tagging, Jumbo Frames, Offloading, and other capabilities.
This page applies only to adapters that have PRO/10GbE in their name. For other 10 gigabit adapters see Advanced Settings for Intel® 10 Gigabit Server Adapters.
NOTES:
- Some features might not be available depending on the operating system and the specific adapters installed.
- Advanced tab layout and feature availability is different when Intel PROSet for Windows* Device Manager is installed.
- On screen help is available when Intel® PROSet for Windows* Device Manager is installed.
Advanced Settings
Jumbo Frames enables or disables Jumbo Frame capability. Jumbo Frames can increase throughput and decrease CPU utilization by putting more data in each frame, thereby sending out fewer frames. The standard Ethernet frame size is 1514 bytes, while Jumbo Frames can contain 4088, 9014, or 16128 bytes. Available settings varies depending on the specific adapter.
Enable Jumbo Frames only if devices across the network support them and are configured to use the same frame size. When setting up Jumbo Frames on other network devices, be aware that network devices calculate Jumbo Frame sizes differently. Some devices include the header information in the frame size while others do not.
Note: Intel adapters do not include header information in the frame size.
| Supported Adapters |
All |
| Default |
Disabled |
| Range |
Disabled (1514), 4088, 9014, and 16128 bytes. (Set the switch 4 bytes higher for CRC, plus 4 bytes if using VLANs.) | |
Locally Administered Address overrides the virtual, user-assigned MAC address of the adapter. This setting does not override the adapter's physical MAC address. To enter a new network address, type a 12-digit hexadecimal number in this box.
| Supported Adapters |
All |
| Default |
None |
| Range |
0000 0000 0001 - FFFF FFFF FFFD
Exceptions:
- Do not use a multicast address (Least Significant Bit of the high byte = 1).
- Do not use all zeros or all Fs.
Note Present Setting: Reverts to original network address of the adapter. | |
Note: In a team, Intel® PROSet uses either:
- The team's LAA if the team has an LAA configured, or
- The primary adapter's permanent MAC address if the team does not have an LAA configure
- Intel PROSet does not use an adapter's LAA if the adapter is the primary adapter in a team and the team has an LAA.
Log Link State Event enables the logging of the following link state changes to the system event log.
- LINK_UP_CHANGE
Indicates that the adapter has established link.
- LINK_DOWN_CHANGE
Indicates that the adapter has lost link.
- LINK_DUPLEX_MISMATCH
Indicates a mismatch in duplex between the adapter and the llink partner
Troubleshooting Tip: To investigate connection problems, click the Link Speed tab and run diagnostics.
Offload Receive IP Checksum enables the adapter to verify the IP checksum of incoming packets. This feature enhances reception performance and reduces CPU utilization.
With Offloading disabled, the operating system verifies the IP checksum.
With Offloading enabled, the adapter completes the verification for the operating system.
| Supported Operating Systems |
Windows* Server 2003, Server, Windows* 2000 |
| Default |
The default varies with the operating system. |
| Range |
On, Off | |
Offload Receive TCP Checksum enables the adapter to verify the TCP or UDP checksum of incoming packets. This feature enhances reception performance and reduces CPU utilization.
With Offloading disabled, the operating system verifies the TCP checksum.
With Offloading enabled, the adapter completes the verification for the operating system.
| Supported Operating Systems |
Windows Server 2003, Server, Windows 2000 |
| Default |
The default varies with the operating system. |
| Range |
On, Off | |
Offload TCP Segmentation enables the adapter to offload the task of segmenting TCP messages into valid Ethernet frames.This feature enhances TCP transmit performance and reduces CPU utilization.
With Offloading off, the operating system performs TCP segmentation.
With Offloading on, the adapter completes the segmentation for the operating system.
| Default |
The default varies with the operating system. |
| Range |
On, Off |
Offload Transmit IP Checksum enables the adapter to compute the IP checksum of outgoing packets. This feature enhances IP transmit performance and reduces CPU utilization.
With Offloading disabled, the operating system verifies the IP checksum.
With Offloading enabled, the adapter completes the verification for the operating system.
| Supported Operating Systems |
Windows Server 2003, Server, Windows 2000 |
| Default |
On |
| Range |
On, Off | |
Offload Transmit TCP Checksum enables the adapter to compute the TCP or UDP checksum of outgoing packets. This feature enhances TCP and UDP transmit performance and reduces CPU utilization.
With Offloading disabled, the operating system verifies the TCP checksum.
With Offloading enabled, the adapter completes the verification for the operating system.
| Supported Operating Systems |
Windows Server 2003, Server, Windows 2000 |
| Default |
On |
| Range |
On, Off | |
QoS Packet Tagging enables the adapter to send and receive IEEE 802.3ac tagged frames, which include 802.1p> QoS and 802.1Q VLAN indications.
| Supported Adapters |
All |
| Default |
Disabled |
| Range |
Enable, Disabled | |
Receive Descriptors defines the number of Receive Descriptors, which are data segments that enable the adapter to allocate received packets to memory. Depending on the size of the packet, each receive packet requires one or more Receive Descriptors.
You might choose to increase the number of Receive Descriptors if you notice a significant decrease in the performance of received traffic. If receive performance is not an issue, use the default setting appropriate to the adapter. The default setting is 256.
Transmit Descriptorsdefines the number of Transmit Descriptors, which are data segments that enable the adapter to track transmit packets in the system memory. Depending on the size of the packet, each transmit packet requires one or more Transmit Descriptors.
You might choose to increase the number of Transmit Descriptors if you notice a possible problem with transmit performance. Although increasing the number of Transmit Descriptors can enhance transmit performance, Transmit Descriptors do consume system memory. If transmit performance is not an issue, use the default setting of 512.
