Flow-Control Receive Enable - H3C S6812 Series Command Reference Manual

Usage guidelines
With TxRx-mode generic flow control configured, an interface can both send and receive flow control
frames:
•
When congested, the interface sends a flow control frame to its peer.
•
Upon receiving a flow control frame from the peer, the interface suspends sending packets.
To implement flow control on a link, enable generic flow control at both ends of the link.
Examples
# Enable TxRx-mode generic flow control on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] flow-control

flow-control receive enable

Use flow-control receive enable to enable Rx-mode generic flow control on an Ethernet port.
Use undo flow-control to disable Rx-mode generic flow control on an Ethernet port.
Syntax
flow-control receive enable
undo flow-control
Default
Rx-mode generic flow control is disabled on Ethernet interfaces.
Views
Ethernet interface view
Predefined user roles
network-admin
Usage guidelines
With Rx-mode flow control enabled, an interface can receive but cannot send flow control frames.
•
When the interface receives a flow control frame from its peer, it suspends sending packets to
the peer.
•
When traffic congestion occurs on the interface, it cannot send flow control frames to the peer.
To handle unidirectional traffic congestion on a link, configure the flow-control receive enable
command at one end, and the flow-control command at the other. To enable both ends of the link to
handle traffic congestion, configure the flow-control command at both ends.
Examples
# Enable Rx-mode generic flow control on Ten-GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-ten-gigabitethernet 1/0/1] flow-control receive enable
