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 | 媖 | to make the configuration effective. |
