Configure IEEE 802.3X Pause Frame Transmit

Configure IEEE 802.3X Pause frame transmit to eliminate or minimize packet loss.

About this task

By default, flow control mode is disabled. When disabled, the system does not generate nor configure the transmission of flow control messages. The system always honors received flow control messages regardless of the flow control mode status. You must enable this mode before you configure an interface to send pause frames.

By default, an interface does not send pause frames.
