Backpressure:
Flow Control for Half Duplex. A condition wherein a switch causes a
transmitting device to hold off on sending data packets until the switch bottleneck has been
eliminated.
Addr.Learning:
Address learning is a service that characterizes a learning bridge, in which
the source MAC address of each received packet is stored so that future packets destined
for that address can be forwarded only to the bridge interface on which that address is
located.
After completing the settings, press “Update” button to take effect. The setting will be
reflected at current status window.
4.3.2 Port mirroring
The port mirroring function is accomplished by setting the following items.
(a) Destination port:
Theoretically it’s possible to set more than one destination port in a
network. Actually the port mirroring function will lower the network throughput, and therefore
it’s recommended to set "only one" destination port in a network.
(b) Monitored packets:
(1)Disable: means this function is disabled. (2)RX: means copy the
incoming packets of the selected source port to the selected destination port. (3)TX: means
copy the outgoing packets of the selected source port to the selected destination port. (4)Tx
& Rx: means the combination of Tx and Rx.
(c) Source port:
The traffic source that will be copied to the destination port.

4.3.3 Bandwidth Control
This page allows the setting of the bandwidth for each port. The TX rate and Rx rate can be
filled with the number ranging 1 to 255. This number will be multiplied by the selected
bandwidth resolution and the result is the real bandwidth.
