Capture
The Capture group allows you to create capture buffers on the probe
that can be requested and uploaded to the management workstation
for decoding and presentation. The group is not supported in this
release of software.
Events
The Events group provides you with the ability to create entries in an
event log and/or send SNMP traps to the management workstation.
Events can originate from a crossed threshold on any RMON variable. In
addition to the standard five traps required by SNMP (link up, link
down, warm start, cold start, and authentication failure), RMON adds
two more: rising threshold and falling threshold.
Effective use of the Events group saves you time; rather than having to
watch real-time graphs for important occurrences, you can depend on
the Event group for notification. Through the SNMP traps, events can
trigger other actions providing a mechanism for an automated response
to certain occurrences.
Benefits of RMON
Using the RMON features of your stack has three main advantages:
■
It improves your efficiency
Using RMON probes allows you to remain at one workstation and
collect information from widely dispersed LAN segments. This means
that the time taken to reach a problem site, set up equipment, and
begin collecting information is largely eliminated.
■
It allows you to manage your network in a more proactive
manner
If they are configured correctly, RMON probes deliver information
before problems occur. This means that you can take action before
they impact on users. In addition, probes record the behavior of
your network, so that you can analyze the causes of problems.
