## Modifying Configuration Parameters

Although the default values should be appropriate in most cases, you may change any of the available options to meet the requirements of your specific system. Once the adapter driver software has been installed, you can use this procedure to verify or change the following adapter properties:

- 802.1p QOS
- Checksum Offload
- Ethernet@WireSpeed™
- Flow Control
- Jumbo Mtu
- Large Send Offload
- Speed & Duplex
- Wake Up Capabilities
- WOL Speed

### Driver Properties Advanced Tab

To configure the adapter parameters, bring up the Driver Properties Advanced tab as follows:

1. Click Start then select Control Panel from the pop-up menu.
2. Click on the Performance Maintenance category, then click on the System Control Panel icon to display the System Properties window.
3. Click the Hardware tab and then click Device Manager. The Device Manager window displays.
4. Scroll down the list of hardware devices to Network Adapters. Click the plus (+) to the left of the icon to display the list of adapters currently configured.
5. Double-click the Gigabit Ethernet Adapter you want to configure. The Gigabit Ethernet Properties window displays, showing the General tab.

6. Click the Advanced tab. A window showing the list of configurable properties (and default values) for the adapter displays.

7. Change the operating parameters as desired. To change adapter operating parameters listed under the Advanced tab, click on the options listed under Properties and then use the pull-down window under Value to change the default or assigned value.

### 802.1p QOS Parameter

The 802.1p QOS parameter is a standard that enables Quality of Service. Disabled by default, select Enable from the Value drop-down menu to enable this parameter. Once enabled, select Disable from the Advanced tab "Value" drop-down menu to disable this parameter.

### Checksum Offload Parameter

Normally the Checksum Offload function is computed by the protocol stack. By selecting one of the Checksum Offload parameters, the checksum can be computed by the Gigabit Ethernet Adapter. To enable one of the Checksum Offload parameters, select the parameter from the Advanced tab "Value" drop-down menu. These parameters are described and shown below:

- Rx TCP/IP Checksum - Enables receive TCP, IP, and UDP checksum offloading
- Tx TCP/IP Checksum - Enables transmit TCP, IP, and UDP checksum offloading
- Tx/Rx TCP/IP Checksum (default) - Enables transmit and receive TCP, IP, and UDP checksum offloading

### Ethernet@WireSpeed™ Parameter

T he Ethernet@WireSpeed parameter enables a 1000BASE-T Ethernet adapter to establish a link at a lower speed when only 2 pairs of wires are available in the cable plant. By default, the adapter is set to Enable. To disable the Ethernet@WireSpeed™ parameter, select Disable from the "Value" drop-down menu as shown below:

- Disable - Disables Ethernet@WireSpeed
- Enable (default) - Enables Ethernet@WireSpeed

### Flow Control Parameter

The Flow Control parameter allows the user to enable or disable the receipt or transmission of PAUSE frames. PAUSE frames enable the adapter and the switch to control the transmit rate. The side that is receiving the PAUSE frame will momentarily stop transmitting. The recommended selection is Disable, which will configure the adapter to ignore PAUSE frames. Disabled by default, to enable Flow Control to receive, transmit, or receive and transmit PAUSE frames, select the appropriate parameter from the Advanced tab "Value" drop-down menu described and shown below.

- Auto - PAUSE frame receipt and transmission is optimized
- Disable - (default) PAUSE frame receipt and transmission is disabled (recommended)
- Rx PAUSE - PAUSE frame receipt is enabled
- Rx/Tx PAUSE - PAUSE frame receipt and transmission is enabled
- Tx PAUSE - PAUSE frame transmission is enabled

### Jumbo Mtu Parameter

The Jumbo Mtu parameter allows the adapter to transmit and receive oversized Ethernet frames that are greater than 1514 but less than 9000 bytes in length. Note that this parameter will require a switch that is able to process large frames.

Set at 1500 bytes by default, to increase the size of the received frames, increment the byte quantity in 500-byte increments from the Advanced tab "Value" counter, shown below.

| NOTE 5705 does not support jumbo frames. It can transmit jumbo packets by TCP segmentation, but the ethernet frame size is still limited to 1514 bytes. Receive frame size is also limited to 1514 bytes.

### Large Send Offload Parameter

Normally the TCP segmentation is done by the protocol stack. By enabling the Large Send Offload value, the TCP segmentation can be done by the Gigabit Ethernet Adapter. To enable the Large Send Offload, select the parameter from the Advanced tab "Value" drop-down menu. These values are described and shown below:

| NOTE Large Send Offload features are only supported on the 5701 NetXtreme Adapter.

- Disable - Disables large send offloading
- Enable (default) - Enables large send offloading

### Speed & Duplex Parameter

The Speed & Duplex parameter allows the user to set the connection speed to the network and mode. Note that Full-Duplex Mode allows the adapter to transmit and receive network data simultaneously. The adapter is set to Auto (optimum connection) by default. Set the speed and mode as described and shown below:

- 10 Mb Full - Sets the speed at 10Mbps and mode to Full Duplex
- 10 Mb Half - Sets the speed at 10Mbps and mode to Half Duplex
- 100 Mb Full - Sets the speed at 100Mbps and mode to Full Duplex
- 100 Mb Half - Sets the speed at 100Mbps and mode to Half Duplex
- Auto - (Default) Sets the speed and mode for optimum network connection (recommended)

| NOTE 1Gbps speed is enabled by selecting Auto.

| NOTES Auto is the recommended selection. This selection allows the adapter to dynamically detect the line speed and duplex mode of the network. Whenever the network capability changes, the adapter will automatically detect and adjust to the new line speed and duplex mode. Ensure that the link partner is also configured for Auto.

### Wake Up Capabilities Parameter

The Wake Up Capabilities parameter allows the user to set the adapter to wake up from a low power mode when it receives a network wake up frame. Two wake up frames are possible: Magic Packet and Wake Up Frame. By default, the adapter is set to Both. To set the adapter to wake up from a frame, select the appropriate Advanced tab parameter from the "Value" drop-down menu as described and shown below:

- Both (default) - Selects both Magic Packet and Wake Up Frame as wake up frames
- Magic Packet - Select Magic Packet as the wake up frame
- None - Selects no wake up frame
- Wake Up Frame - Selects Wake Up Frame as the wake up frame

### WOL Speed Parameter

The WOL Speed parameter allows the user to select the speed at which the adapter connects to the network during Wake-on-LAN mode. By default, the adapter is set to Auto. Set the speed as described and shown below:

| NOTE WOL Speed at 100 Mb is only supported on the 5701 NetXtreme Adapter.

- 10 Mb - Sets the speed at 10 Mb
- 100 Mb - Sets the speed at 100 Mb
- Auto (default) - Sets the speed for optimum network connection

### Save Settings

1. When the adapter parameter configuration is complete, click OK at the Gigabit Ethernet Controller Properties screen to accept the settings.
2. If prompted to restart your computer, click Yes. Note that, while it is not necessary to reboot the system for new adapter properties to take effect, rebooting is recommended to reinitialize all registers.
3. Verify that the adapter port LEDs operate as described in Table 1 in the Introduction.

### Power Management

Power management specifies whether the operating system turns off the selected device if that device is able to be turned off. If the device is busy doing something, however, (servicing a call, for example), the operating system will not shut down the device. The operating system will try to shut down every possible device only when it is hibernating. Some devices must stay on at all times. If you need the device to stay on at all times, do not check this box.

| NOTE To enable the Wake-on LAN in standby mode for the Broadcom NetXtreme™ Gigabit Ethernet adapter you must select the "Allow the device to bring the computer out of standby" checkbox.

| NOTE In order for WOL to operate properly this feature must be enabled on the adapter card. To enable WOL refer to the b57util: Utilitites Program User's Guide for details.
