Usage guidelines
To implement flow control on a link, enable the generic flow control function at both ends of the link.
TxRx mode generic flow control enables an Ethernet interface to perform the following actions:
• Receive common pause frames from its peer.
• Send common pause frames to notify its peer of congestions.
With the flow-control command 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.
Examples
# Enable TxRx mode generic flow control on the interface GigabitEthernet 1/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] flow-control
flow-control receive enable
CAUTION:
Configuring generic flow control on an Ethernet interface will cause link-up and link-down events
before the interface finally stays up.
Use flow-control receive enable to enable Rx mode generic flow control on an Ethernet port.
Use undo flow-control to disable generic flow control on an Ethernet interface.
Syntax
flow-control receive enable
undo flow-control
Default
Rx flow control is disabled on Ethernet interfaces.
