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.
Since current network management standards comprise a set of protocols, the better simulators integrate the current network management standards, such as NetFlow, command-line interfaces (CLI), etc.
Universal Metric to Flow (UMF) technology enhances the ability to utilize Cisco NetFlow data for rapid traffic analysis.
