Design Considerations
The C3 supports RMON Packet Capture/Filter Sampling through both the CLI and MIBs, but with
the following constraints:
21-2 RMON Configuration
What It Does...
Records periodic statistical
samples from a network.
Periodically gathers
statistical samples from
variables in the probe and
compares them with
previously configured
thresholds. If the monitored
variable crosses a
threshold, an event is
generated.
Controls the generation and
notification of events from
the device.
Allows packets to be
matched by a filter
equation. These matched
packets form a data stream
or "channel" that may be
captured.
Allows packets to be
captured upon a filter
match.
What It Monitors...
Sample period, number of
samples and item(s) sampled.
Alarm type, interval, starting
threshold, stop threshold.
Event type, description, last
time event was sent.
Packets matching the filter
configuration.
Packets matching the filter
configuration.
