6. Flow Control: User can set flow control function to ON or OFF in Full Duplex mode.
7. Back Pressure: User can set backpressure to ON or OFF in Half Duplex mode.
8. Band Width: Ports 1 ~ 24 support per-port ingress and egress rate control. For
example, assume port 1 is 10Mbps, users can set its effective egress rate at 1Mbps
and ingress rate at 500Kbps. The SmartGST-2402M will perform flow control or
backpressure to confine the ingress rate to meet the specified rate.
9. In: Type the effective port ingress rate. The valid range is 0 ~ 1000. Units are 100K.
(0) Disable rate control, 1 ~ 1000: valid rate value
10. Out: Type the effective port egress rate. The valid range is 0 ~ 1000. The unit is
100K. . (0) Disable rate control, 1 ~ 1000: valid rate value 0: disable rate control.
11. Priority: The static priority is based on each port. If you set the port to high priority,
incoming frames from this port will always be high priority frames.
12. Security: A port in security mode will be “locked” without permission of address
learning. Only the incoming packets with SMAC already existing in the address table
can be forwarded normally. User can disable the port from learning any new MAC
addresses, then use the static MAC addresses screen to define a list of MAC
addresses that can use the secure port. Enter the settings and click Apply button to

The Link Aggregation Control Protocol (LACP) provides a standardized means for
exchanging information between Partner Systems on a link. LACP allows their Link
Aggregation Control instances to reach agreement on the identity of the Link
Aggregation Group to which the link belongs, moves the link to that Link Aggregation
Group, and enables its transmission and reception to function in an orderly manner.
Basically, Link aggregation lets you group up to eight consecutive ports into a single
dedicated connection. This feature can expand bandwidth to a device on the network.
LACP operation requires full-duplex mode. For more detailed information, refer to
the IEEE 802.3ad standard.
