FLOWCONTROL ON
Syntax
flowcontrol [send|receive] on
Parameters
send Turns on flow control on the send side.
receive Turns on flow control on the receive side.
Description
Use the FLOWCONTROL ON command to enable flow control and
configure the flow control mode for the interface.
Flow control enables connected Ethernet ports to control traffic rates
during congestion by allowing congested nodes to pause link operation at
the other end. If one port experiences congestion, and cannot receive any
more traffic, it notifies the other port to stop sending until the condition
clears. When the local device detects congestion at its end, it notifies the
remote device by sending a pause frame. On receiving a pause frame, the
remote device stops sending data packets, which prevents loss of data
packets during the congestion period.
