GS108T and GS110TP Smart Switch Software Administration Manual 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 highpriority 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, click Switching  Ports, and then click the Flow Control link. Figure 3-2 To configure global flow control settings: 1. From the Global Flow Control (IEEE 802.3x) Mode field, enable or disable IEEE 802.3x flow control on the system. The factory default is Disable. • Enable. The switch sends pause packets if the port buffers become full. • Disable. The switch does not send pause packets if the port buffers become full. 2.

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, click
Switching
Ports
, and then click the
Flow Control
link.
To configure global flow control settings:
1.
From the Global Flow Control (IEEE 802.3x) Mode field, enable or disable IEEE 802.3x flow
control on the system. The factory default is Disable.
Enable
. The switch sends pause packets if the port buffers become full.
Disable
. The switch does not send pause packets if the port buffers become full.
2.
Click
Cancel
to cancel the configuration on the screen and reset the data on the screen to the
latest value of the switch.
3.
If you change the mode, click
Apply
to apply the changes to the system.
