CONFIGURING RMON
HISTORY SAMPLES
Use the Administration > RMON (Configure Interface - Add - History) page
to collect statistics on a physical interface to monitor network utilization,
packet types, and errors. A historical record of activity can be used to track
down intermittent problems. The record can be used to establish normal
baseline activity, which may reveal problems associated with high traffic
levels, broadcast storms, or other unusual events. It can also be used to
predict network growth and plan for expansion before your network
becomes too overloaded.
