Using Monitor
You can monitor statistics in real time from the Moxa DSL Ethernet extender’s web console and serial console.
Monitor by DSL Ethernet extender
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 DSL Ethernet extender’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
DSL Ethernet extender, 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 DSL Port (D1)
Access the Monitor by selecting D1 from the pull-down list. By selecting this, users can view graphs that show
all Packets, TX Packets, RX Packets, or Error Packets activity. The height of the bar represents Packets/s for the
type of packet. 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. The table shows below the
graph chart displays the actual link status, data rate, SNR (signal-to-noise ratio) and terminal type (CO/CPE)
after negotiation.
