SNMP Traps enable an agent to notify the management station of significant events by way of an unsolicited SNMP message. Trap PDUs include current sysUpTime value, an OID identifying the type of trap and optional variable bindings. Destination addressing for traps is determined in an application-specific manner typically through trap ...
In short, RMON is designed for "flow-based" monitoring, while SNMP is often used for "device-based" management. RMON is similar to other flow-based monitoring technologies such as NetFlow and SFlow because the data collected deals mainly with traffic patterns rather than the status of individual devices.
The product does not rely on a software agent that must run on hosts it is monitoring, so that data can be pushed back to a central server. "Supported" means that an agent may be used, but is not mandatory. An SNMP daemon does not count as an agent. SNMP Able to retrieve and report on SNMP statistics.

Alternatively, SNMP alarms generated by managed taps can alert network managers to link conditions that merit examination by analyzers to intrusion detection systems. Some taps get some of their power (i.e., for the pass-through ) or all of their power (i.e., for both pass-through and monitor ) from the network itself.
MRTG uses the Simple Network Management Protocol (SNMP) to send requests with two object identifiers (OIDs) to a device. The device, which must be SNMP-enabled, will have a management information base (MIB) to look up the OIDs specified. After collecting the information it will send back the raw data encapsulated in an SNMP protocol.
