To change the Flow Control property, do the following:

1.For Windows Server 2003 and Windows XP systems, access the System Properties Dialog Box. See “Modifying Configuration Properties” on page 39.

For Windows 2008 R2, Windows 7, and Windows Vista systems, access the Device Manger for your operating system:

ˆTo access the Device Manager window in Windows 2008 R2 or Windows 7, see “Selecting the Device Manager in Windows 2008 R2 and Windows 7” on page 44.

ˆTo access the Windows Vista Device Manager, see “Selecting the Device Manager in Windows Vista” on page 46.

2.Click the Advanced tab.

The Advanced tab is shown in Figure 21 on page 56.

3.From the Property list on the Advanced tab, select Flow Control.

4.From the Value list on the Advanced tab, select one of the following:

ˆAuto - (default) PAUSE frame receipt and transmission is optimized.

ˆDisable - PAUSE frame receipt and transmission is disabled (recommended).

ˆRx PAUSE - PAUSE frame receipt is enabled.

ˆRx/Tx PAUSE - PAUSE frame receipt and transmission is enabled.

ˆTx PAUSE - PAUSE frame transmission is enabled.

5.Click OK.

6.If prompted to restart your computer, click Yes.

Although it is not necessary to reboot the system for new adapter properties to take effect, rebooting is recommended to reinitialize all registers.

7.Verify that the port LED operates as described in “LEDs” on page 18.

Jumbo Mtu The Jumbo Mtu property allows the adapter to transmit and receive oversized Ethernet frames that are greater than 1,514 bytes but less than 9,000 bytes in length. Note that this property requires a switch that is able to process large frames.

By default, the Jumbo Mtu property is set to 1500 bytes.
