## Jumbo Frames

Jumbo frames are Ethernet frames which are larger than 1518 bytes, that can be used to reduce server CPU utilization and improve wire efficiency of the entire network.

By putting more data in fewer packets, jumbo frames can increase throughput and decrease CPU utilization. However, additional latency may be introduced.

End-to-end network hardware must support this capability otherwise packets will be dropped.

To configure jumbo frames at the switch, consult your network administrator or switch User's Guide.

- Supported protocols are limited to IP (TCP, UDP).

- Jumbo frames require compatible switch connections that forward jumbo frames. Contact your switch vendor for more information.

- Configuring jumbo frames is a manual process. Unlike speed and duplex auto-negotiation, there is no method of indicating Jumbo Frame support between switches and servers.

- When standard sized Ethernet frames are used (64 to 1518 Bytes) there is no benefit to configuring Jumbo frames.

- Jumbo Frames can be implemented simultaneously with VLANs.

| NOTE: The jumbo frame setting at the switch must be set to at least 8 bytes larger than the adapter setting for Windows operating systems, and at least 22 bytes larger for all other operating systems.

### Supported Operating Systems

- Windows NT 4.0 - See the Windows NT Driver page.

- Windows 2000, XP Professional - See the Windows 2000 Driver page.

- NetWare 6 - See the NetWare Driver page.

- Linux - See the Linux Driver page.

- Solaris - See the Solaris Driver page.

- FreeBSD - See the FreeBSD Driver page.

## Quality of Service (QoS)

QoS allows the adapter to send and receive IEEE 802.3ac tagged frames. 802.3ac tagged frames include 802.1p priority-tagged frames and 802.1Q VLAN-tagged frames. In order to implement QoS, the adapter must be connected to a switch that supports and is configured for QoS. Priority-tagged frames allow real-time programs to make the most efficient use of network bandwidth. High priority packets are processed before lower priority packets.

In order to implement QoS, the adapter must be connected to a switch that supports and is configured for 802.1p QoS.

Tagging is enabled and disabled in the "Advanced Settings" tab of the Intel® PROSet control panel utility. You must set "QoS Packet Tagging" to "Enabled".

Windows 2000 has its own utility for 802.1p packet prioritization. For more information on the Windows 2000 utility, see the Windows 2000 system help. Use the "Index" tab and search for the term "QoS". Select the topic "Windows 2000 Administration Tools."

Additional information is available at the QoS WMI Provider page.

### Supported Operating Systems

- Microsoft Windows 2000 and XP

## Simple Network Management Protocol (SNMP)

The Simple Network Management Protocol (SNMP) is a protocol for managing networks via messages (called "Traps") sent from SNMP-compliant network components and collected by one or more servers. The provided SNMP utilities install the Intel SNMP client agent available for Windows (2000, XP), and Linux. This utility should only be employed by experienced network administrators. Additional software/services must be installed on your network prior to installing the Intel SNMP agent.

#### Supported Operating Systems

- Microsoft Windows (2000, XP Professional)

- Linux

You can install the SNMP agent by double-clicking Intel(R) LAN Adapters SNMP Agent.msi.

- If you are running a 32-bit operating system, use the file located in the SNMP\Agent\Windows\IA32 directory.
- If you are running a 64-bit operating system, use the file located in the SNMP\Agent\Windows\Itanium directory.

Once installed, you can view additional information in \Program Files\Intel\ilansnmp\.

## DMI, WMI Management Software Support

Optional management software is also available in this release:

- The DMI 2.0 Service Provider (SP) and Client Instrumentation 3.0 for Windows (CI) are updated software modules that allow standards-based DMI 2.0 applications, including Intel's LANDesk(R) Client Manager, to monitor the status of PCI adapters. This software can be installed using the Intel(R) PRO Intelligent Installer on the Intel CD. It is also located under \WINDOWS\DMI\WIN32 and \WINDOWS\DMI\WIN32_SP (Service Provider software). See the DMI topic for information about DMI.

- The WMI Provider for 32-bit operating systems can be installed using:

  - The Intel PRO Intelligent Installer on the Intel CD

  - Setup.exe in the \WINDOWS\WBEM\WMI\IBA directory (Boot Agent version)

  - Setup.exe in the \WINDOWS\WBEM\WMI\NIC\IA32 directory (Adapter version). See the WMI topic for information about the Intel(R) PRO Network Adapter WMI Provider.

| NOTE: DMI is supported on Windows NT 4.0 SP3, 95, 98, 2000, ME, and XP Professional.
| NOTE: WMI instrumentation does not support VLANs.

## Save and Restore

This feature gives you the option of copying the current configuration settings in Intel PROSet to an external file (such as on a floppy disk) as a backup measure. In the event of a hard drive failure, the restore feature will reinstate most of your former settings. (This feature does not save/restore the network drivers or the protocol addresses.)

Restoring network configuration settings can only be done on the same system (with the same configuration) on which the save was performed.

| NOTE: Only Intel PROSet settings (including teaming and VLANs) are saved. The adapter's IP address is not stored along with network configuration settings.

More information on Save/Restore can be found in the Intel PROSet online help.

### Supported Operating Systems

- Windows (98SE, Me, NT 4.0, 2000, XP)
