5.2.4Duplex Mode

Only unidirectional communication is practicable on half duplex mode, and bidirectional communication is practicable on full duplex mode. By transmitting packet for two ways, Ethernet bandwidth is enlarged two times- 10Mbps to 20Mbps, 100Mbps to 200Mbps.

To set duplex mode, use the following command.

Command	Mode	Description
port duplex PORTS {full half}	Bridge	Sets full or half duplex mode of specified port, enter the
		port number.

The following is an example of configuring duplex mode of port 1 as half mode and show- ing it.

5.2.5Flow Control

Ethernet ports on the switches use flow control to restrain the transmission of packets to the port for a period time. Typically, if the receive buffer becomes full, the port transmits a pause packet that tells remote ports to delay sending more packets for a specified period time. In addition, the Ethernet ports can receive and act upon pause packets from other devices.
