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.
