Using the Monitor
You can monitor statistics in real time from the TN-5500’s web console and serial console.
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 TN-5500’s 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 TN-5500, 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.
