Port Control
In Port Control you can configure the settings of each port to control the connection
parameters.

Port: Scroll up/down the scroll bar and click on the port number to choose a
particular port to be configured.

State: Enable/disable the port. If the port state is set on
‗Disable‘, the port will not
be able to receive or transmit any packet.

Negotiation: Options include Auto and Force. With this parameter set on Auto ,
the speed and duplex fields display in grey, which means the port are negotiated
automatically. When you set it on Force , you have to set the speed and duplex
mode manually by clicking the pull-down menus of the Speed and Duplex fields.

Speed: It is available for selecting when the Negotiation field is set on Force.
When the Negotiation field is set on Auto, this field becomes a read-only field
displaying in grey.

Duplex: It is available for selecting when the Negotiation field is set on Force.
When the Negotiation field is set on Auto, this field becomes a read-only field
displaying in grey.

Flow Control: Whether the receiving node sends feedback to the sending node is
determined by this item. With this item enabled, if the input data rate of the
receiving device exceeds, the receiving device will send a PAUSE frame which
halts the transmission of the sender for a specified period of time. With this item
disabled, the receiving device will drop the packets it is unable to process.

Security: When 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. Keep in mind that the Security item is
set as On so that the MAC violation event log/email alert will then be issued.
Further information please see the segments of MAC Address Table
