Flow Control
IEEE 802.3x flow control works by pausing a port when the port becomes oversubscribed and
dropping all traffic for small bursts of time during the congestion condition. This can lead to high-
priority and/or network control traffic loss. When IEEE 802.3x flow control is enabled, lower
speed switches can communicate with higher speed switches by requesting that the higher speed
switch refrains from sending packets. Transmissions are temporarily halted to prevent buffer
overflows.
To display the Flow Control page:
1. Click Switching Ports, and then click the Flow Control link.
2. If you change the mode, click Apply to apply the changes to the system.
