FC - Flow control can eliminate frame loss by “blocking” traffic from
end stations or segments connected directly to the switch when its
buffers fill. When enabled, back pressure is used for half-duplex
operation and IEEE 802.3-2005 (formally IEEE 802.3x) for full-
duplex operation.
Avoid using flow control on a port connected to a hub unless it is
actually required to solve a problem. Otherwise back pressure
jamming signals may degrade overall performance for the segment
attached to the hub.
(Default: Autonegotiation enabled; Advertised capabilities for
100Base-TX – 10half, 10full, 100half, 100full;
100Base-FX – 100full
1000BASE-T – 10half, 10full, 100half, 100full, 1000full;
1000Base-SX/LX/LH – 1000full)
◆ Speed/Duplex – Allows you to manually set the port speed and
duplex mode. (i.e., with auto-negotiation disabled)
◆ Flow Control – Allows automatic or manual selection of flow control.
