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.
The GS716T and GS724T supports two combo ports using 1000M SFP modules. Each
combo port can operate in either ‘copper’ or ‘fiber’ mode. When a cable is plugged into the
RJ-45 port, copper mode is used. When a SFP module is plugged in, fiber mode is used.

The system automatically detects the media that is in use on a combo port and operates
accordingly. The SFP transceiver takes precedence over the RJ-45 copper port.
