Monitoring
Network Segments
Using RMON-1
Agents
Many sites (particularly in a switched environment) have large numbers of
network segments, and it may be too expensive to monitor all segments
with RMON-2 agents. You can use any existing embedded RMON-1 only
devices (hubs, switches, routers etc.) instead, to produce lightweight
activity reports for these segments.
Data from RMON-1 only agents is only used in segment activity reports,
and does not appear in the Map.
To produce a lightweight segment activity report, follow these steps:
1 In the Configure Agents dialog box, add and enable the RMON-1 devices
and interfaces you want to use to collect network traffic data.
Traffix
™
Manager will automatically begin to collect data from the
enabled interfaces.
2 From the Report Manager, schedule a daily Segment Activity report for
the next morning (weekly and monthly reports can also be scheduled).
When you look at the report, you will find that the following graphs are
incomplete:
■
Protocol Distribution of Segment By Octets (no data).
■
Key to graph with no data — no key is displayed.
■
Protocol Distribution By Octets With Packets Overlaid — only the
packet overlay appears.
The remaining graphs and tables all appear in full.
RMON-1 only segments will never appear in a TopN Segments report
since the Reporter uses (RMON-2) protocol information to calculate the
top N segments.
