From this view you can see statistics about the number of good or bad packets
each port has received and transmitted, based on how you have configured the
Counter Mode setting (see step 7 on page 36).
The bottom half of the window shows Remote MONitoring (RMON) counters for
the LAN port and each of the four PAN ports on the IntelliJack. RMON counters
are extensions to the Simple Network Management Protocol (SNMP) that provide
comprehensive network monitoring capabilities (see appendix C, page 71 for
detailed information).
12 To load the counter information from the IntelliJack, click the Read button.
This window lets you monitor the traffic through your network by displaying
statistics for many types of packets. The left side shows Ingress counters for
packets coming into the IntelliJack’s port. The right side shows Egress counters for
packets leaving the port.
