State:
Set the communication capability of the port is Enabled or Disabled.
When enabled, traffic can be transmitted and received via this port.
When disabled, the port is blocked and no traffic can be transferred
through this port. Port State is configurable by the user. There are only
two states “Enable” and “Disable” able to choose. If you set a port’s state
“Disable”, then that port is prohibited to pass any traffic, even it looks
Link up.

Default: Enable.
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.

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.
Power Saving:
The parameter will enable or disable to verify switches have the ability to
consider the length of any Ethernet cable connected for adjustment of
power usage accordingly. Shorter lengths require less power. link-down
mode removes power for each port that does not have a device attached.
