Speed/Duplex:
Set the speed and duplex of the port. In speed, 10/100Mbps baud rate is
available for Fast Ethernet, Gigabit module in port 25, 26. If the media is
1Gbps fiber, it is always 1000Mbps and the duplex is full only. If the
media is TP, the Speed/Duplex is comprised of the combination of speed
mode, 10/100/1000Mbps, and duplex mode, full duplex and half duplex.
The following table summarized the function the media supports.
Media type NWay Speed Duplex
100M TP ON/OFF 10/100M Full/Half
1000M TP ON/OFF 10/100/1000M Full for all, Half for 10/100
1000M Fiber ON/OFF 1000M Full
In Auto-negotiation mode, no default value. In Forced mode, default
value depends on your setting.
Flow Control:
There are two modes to choose in flow control, including Symmetric and
Asymmetric. If flow control is set Symmetric, both parties can send
PAUSE frame to the transmitting device(s) if the receiving port is too
busy to handle. When it is set Asymmetric, this will let the receiving port
care the PAUSE frame from transmitting device(s), but it doesn’t send
PAUSE frame. This is one-way flow control.
Default: Symmetric.
