Usage guidelines
TxRx mode flow control allows an Ethernet interface to receive common pause frames from its peer, and
send common pause frames to notify its peer of congestion.
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 its peer, the interface suspends sending packets.
To implement flow control on a link, enable the generic flow control function at both ends of the link.
Examples
# Enable TxRx mode generic flow control on the interface GigabitEthernet 0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1
[Sysname-GigabitEthernet0/1] flow-control
interface
Use interface to enter interface or subinterface view. If you specify the interface-number.subnumber
argument and the subinterface does not exist, this command creates first the subinterface, and then
enters subinterface view.
Syntax
interface interface-type { interface-number | interface-number.subnumber }

Parameters
interface-type: Specifies an interface type.
interface-number: Specifies an interface number.
interface-number.subnumber: Specifies a subinterface number, where interface-number is an interface
number, and subnumber is the number of a subinterface created under the interface. The subnumber
argument ranges from 1 to 4094.
Examples
# Enter GigabitEthernet 0/1 interface view (assuming that the interface is a Layer 2 Ethernet interface).
