Procedure 5-4.3: Enable/Disable 802.3x switch flow control

- Overview

Use this procedure to enable/disable 802.3x flow control on the VLNC4x switch.

This command enables 802.3x flow control for the switch. A port-specific setting overrides the global switch setting.

802.3x flow control works by pausing a port when the port becomes oversubscribed and dropping all traffic for small periods of time during the congested condition. This can lead to high-priority and network control traffic being lost.

Step
 
1

Login to the VLNC4x.

2

From the Navigation menu, select System → Configuration → Switch.

Result:

The Switch Configuration window displays the current configuration.

3

Select Enable or Disable as required, then click Submit.

Equivalent CLI command:

  • From the Global Config Mode, enter storm-control flowcontrol to enable flow control.

  • From the Global Config Mode, enter no storm-control flowcontrol to disable flow control.

    By default, storm-control for flowcontrol traffic is disabled.
