■
1000full (Gigabit ports only) - Supports 1000 Mbps full-duplex
operation
■
Sym - Check this item to transmit and receive pause frames.
■
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 on Gigabit ports, disabled on 10G
ports; Advertised capabilities for
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.
