This appendix provides an overview of RMON and describes the specific

 RMON implementation. 

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 
out-of-band connections.

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.
