Parameter description:
y 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.
y 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.
y 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.
3.4.3 Simple Counter
The function of Simple Counter collects any information and provides the counting about the traffic of the port,
no matter the packet is good or bad. As below, the window can show all ports’ counter information at the same
time. Each data field has 12-digit long. If the counting is overflow, the counter will be reset and restart counting.
The data is updated every time interval defined by the user. The valid range is 3 to 10 seconds. The Refresh
