What is RMON?

Transcend SmartAgent RMON provides a mechanism for remote
monitoring and analysis of a Local Area Network. RMON is the common
abbreviation for the Remote Monitoring MIB as defined by the IETF in
documents RFC 1271 and RFC 1757. A typical RMON system consists of
two components:
The Probe - Connects to a LAN segment, examines all the LAN traffic
on that segment and keeps a summary of statistics (including
historical data) in its local memory.
The Management Console - Communicates with the Probe and
collects the summarized data from it. The console does not have to be
on the same network as the probe and can manage the probe by
either in-band (SNMP) or out-of-band connections.
The IETF defines the following groups of information supplied by
ethernet RMON probes.
