Parameters

Parameter	Description	Value
default	Specifies the flow control to the default.	-
receive	When the receive is enabled, the interface can receive pause frames and respond to pause frames. When a pause frame is received, the interface stops sending traffic.	-

Usage Guidelines

Usage Scenario

Ensure that both devices at two ends of a link support flow control.

Precautions

If the peer device does not support flow control, disabling flow control on the local device is recommended.

Example

# Enable flow control for incoming flows on GE 0/1/1.

<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet 0/1/1
[~HUAWEI-GigabitEthernet0/1/1] flow control receive

# Enable flow control for outgoing flows on GE 0/1/1.
