Port Control 
 
In Port Control, you can pull down the selection items to set the parameters of each port to control the 
transmitting/receiving packets. 
 
•  Port: Select the port that you want to configure. 
•  State:  Current port status. The port can be set to disable or enable mode. If the port state is set as 
‘Disable’, it will not receive or transmit any packet. 
•  Negotiation:  Auto and Force. Being set as Auto, the speed and duplex mode are negotiated 
automatically. When you set it as Force, you have to assign the speed and duplex mode manually. 
•  Speed: It is available for selecting when the Negotiation column is set as Force. When the Negotiation 
column is set as Auto, this column is read only. 
•  Duplex: It is available for selecting when the Negotiation column is set as Force. When the Negotiation 
column is set as Auto, this column is read only. 
•  Flow Control: Set flow control function as Enable or Disable. When enabled, once the device exceed 
the input data rate of another device as a result the receiving device will send a PAUSE frame which 
halts the transmission of the sender for a specified period of time. When disabled, the receiving device 
will drop the packet if too much to process. 
•  Security: Once the Security selection is set as ‘On’, any access from the device which connects to this 
port will be blocked unless the MAC address of the device is included in the static MAC address table. 
See the segment of Static MAC Table. 
• Click Apply  to make the configuration effective.
