Monitor by Switch
Access the Monitor by selecting System from the left selection bar. Monitor by System allows the user to view
a graph that shows the combined data transmission activity of all of the Moxa switch’s 18 ports. Click one of the
four options—Total Packets, TX Packets, RX Packets, or Error Packets—to view transmission activity of
specific types of packets. Recall that TX Packets are packets sent out from the Moxa switch, RX Packets are
packets received from connected devices, and Error Packets are packets that did not pass TCP/IP’s error
checking algorithm. The Total Packets option displays a graph that combines TX, RX, and TX Error, RX Error
Packets activity. The graph displays data transmission activity by showing Packets/s (i.e., packets per second,
or pps) versus sec. (seconds). In fact, three curves are displayed on the same graph: Uni-cast packets (in red
color), Multi-cast packets (in green color), and Broad-cast packets (in blue color). The graph is updated
every few seconds, allowing the user to analyze data transmission activity in real-time.
Monitor by Port
Access the Monitor by Port function by selecting ALL 10/100M or 1G Ports or Port i, in which i = 1, 2, …, G2,
from the left pull-down list. The Port i options are identical to the Monitor by System function discussed above,
in that users can view graphs that show All Packets, TX Packets, RX Packets, or Error Packets activity, but in
this case, only for an individual port. The All Ports option is essentially a graphical display of the individual port
activity that can be viewed with the Console Monitor function discussed above. The All Ports option shows three
vertical bars for each port. The height of the bar represents Packets/s for the type of packet, at the instant the
bar is being viewed. That is, as time progresses, the height of the bar moves up or down so that the user can
view the change in the rate of packet transmission. The blue colored bar shows Uni-cast packets, the red
colored bar shows Multi-cast packets, and the orange colored bar shows Broad-cast packets. The graph is
updated every few seconds, allowing the user to analyze data transmission activity in real-time.
