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 GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1

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.

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 GigabitEthernet 1/0/1.
