Managing RMON
RMON (Remote Networking Monitoring) is an SNMP specification that enables an
SNMP agent in the device to proactively monitor traffic statistics over a given
period and send traps to an SNMP manager. The local SNMP agent compares
actual, real-time counters against predefined thresholds and generates alarms,
without the need for polling by a central SNMP management platform. This is an
effective mechanism for proactive management, provided that you have the
correct thresholds set relative to your network’s base line.
RMON decreases the traffic between the manager and the device because the
SNMP manager does not have to poll the device frequently for information, and
enables the manager to get timely status reports, because the device reports
events as they occur.
With this feature, you can perform the following actions:
• View the current statistics (since the counter values were cleared). You can
also collect the values of these counters over a period of time, and then
view the table of collected data, where each collected set is a single line of
the History tab.
