REMOTE MONITORING (RMON) B TECHNOLOGY
This appendix provides an overview of RMON and describes the specific
CoreBuilder™ RMON implementation.
What Is RMON? The Remote Monitoring (RMON) Management Information Base (MIB) provides a way to monitor and analyze a local area network LAN from a remote location. RMON is defined by the Internet Engineering Task Force (IETF) in documents RFC 1271 and RFC 1757. A typical RMON implementation has two components:
■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.
■Management Console — Communicates with the probe and collects the summarized data from it. The console does not need to reside on the same network as the probe. It can manage the probe through SNMP or through
The RMON specification consists almost entirely of the definition of the MIB. The RMON MIB contains standard MIB variables defined to collect comprehensive network statistics that alert a network administrator to significant network events. If the embedded RMON agent operates full time, it collects data on the correct port when the relevant network event occurs.
