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:
Whether or not the receiving node sends feedback to the sending node is
determined by this item. When enabled, once the device exceeds the input data
rate of another device, 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:
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. See the segment of MAC Address
Table—Static MAC Addresses.
5.5.3 Port Trunk
Port trunking is the combination of several ports or network cables to expand the connection speed beyond the limits of
any one single port or network cable. Link Aggregation Control Protocol (LACP), which is a protocol running on layer 2,
provides a standardized means in accordance with IEEE 802.3ad to bundle several physical ports together to form a
single logical channel. All the ports within the logical channel or so-called logical aggregator work at the same connection
speed and LACP operation requires full-duplex mode.
