FLOW CONTROL RECEIVE

Syntax

flow control receive on|off

Parameters

receive

Controls flow control on traffic that is received by an
interface. Choose from the following options:

on

Enables flow control.

off

Disables flow control.

Description

Use the FLOWCONTROL RECEIVE command to enable an interface to
receive traffic using flow control.

Flow control enables connected Ethernet ports (or interfaces) 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 another port to stop sending traffic until
the condition clears. When the local device detects congestion at its end, it
notifies the remote device by sending a pause frame. After the remote
device receives a pause frame, the remote device stops sending data
packets. This prevents the loss of data packets during the congestion
period.

Command Mode

The following commands set port 7 to flow control receive on.
