■Flow Control – Enables and disables flow control on the port. When flow control is enabled for the port, the Switch regulates the packet flow so that a sending device does not transmit more packets than a receiving device can process. If flow control is disabled, packets may be dropped under certain periods of high traffic.
Flow control is disabled by default.
■Speed – Sets the speed mode of the port. Available options include auto, 10, 100, and 1000. For 1000 Mbps connections, see “Speed/Duplex for 1000 Mbps Connections” below.
Auto (or autonegotiation) sets the optimum combination of speed and duplex that can be supported by both ends of the link.
■Duplex – Sets the duplex mode of the port. Available options include Auto, Half, and Full.
CAUTION: It is advised not to enable Flow Control on ports that will be connected to telephony and other time sensitive traffic as it may hamper the QoS performance.

Speed/Duplex for 1000 Mbps Connections
You cannot preset the speed to 1000 Mbps. To run a port at 1000 Mbps, you must enable autonegotiation for the port. When autonegotiation is enabled, the Switch will automatically connect at 1000 Mbps, providing the connected device also supports this speed.
