5.10 RMON Manager
RMON Manager is an application for managing devices that support RFC 1757 and
RFC 1513, the Remote Network Monitoring Management Information Base (MIB)
for Ethernet and Token Ring, respectively.
RMON Manager gathers a wide variety of statistical information about network
operation by examining each packet passed on a network segment. Segment statistics
are stored in counters within the agent (often called a probe). The counters are
continuously updated and reset at powerup.
In addition to statistics, network traffic patterns are captured and stored. You can
also capture and examine individual packets or sequences of packets to identify and
isolate network operational software or hardware problems.
A typical network consists of multiple network segments with one RMON agent
connected to each segment. You can control the module from a centrally located
network management station (NMS). The NMS has a user interface that permits you
to request and examine data from selected modules. You can have multiple clients
performing network diagnostic functions from multiple locations such as primary
and secondary network management centers.
NOTE
An RMON agent is a hardware and software device that you attach to a spe-
cific network segment. The agent gathers statistical information for that seg-
ment and provides a window into the segment that you use to observe and
analyze network data.
