Chapter 5: Setting Advanced Properties

Flow Control

The Flow Control property allows you to enable or disable the receipt or transmission of PAUSE frames which allow the adapter and the switch to control the transmit rate. The port side that receives the PAUSE frame momentarily stops transmitting. The recommended selection is Disable, which configures the adapter to ignore PAUSE frames. By default, the Flow Control property is disabled.

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:

To 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.

To access the Windows Vista Device Manager, see “Selecting the Device Manager in Windows Vista” on page 45.

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:

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

Disable - 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.

5.Click OK.

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

Although it is not necessary to reboot the system for the new settings, rebooting is recommended to reinitialize all registers.

7.Verify that the port LED operates as described in “LEDs” on page 16.
