 and Remote Monitoring 
Overview 
RMON is an abbreviation for the Remote Monitoring MIB 
(Management Information Base).
by the Internet Engineering Task 
1757, which defines how networks can be monitored 
remotely. 
 
RMONs typically consist of two components: an RMON probe 
and a management workstation: 
 
- The RMON probe is an intelligent device or software agent that continually 
collects statistics about a LAN segment or VLAN. The RMON probe 
transfers the collected data to a management workstation on request or 
when a pre-defined threshold is reached. 
 
- The management workstation collects the statistics that the RMON probe 
gathers. The workstation can reside on the same network as the probe, or it 
can have an in-band or out-of-band connection to the probe. 
 
The switch provides RMON capabilities that allow network 
administrators to set parameters and view statistical counters 
defined in MIB-II, Bridge MIB, and RMON MIB. RMON 
activities are performed at a Network Management Station 
running an SNMP network management application with 
graphical user interface. 
 
 RMON is a system defined
