Using RMON Services
114070 Rev. A 2-3
RMON Benefits
RMON provides the following benefits to network managers:
Powerful monitoring and analysis
Network managers can evaluate LAN segment statistics and long-term
trending, node patterns, top bandwidth users, and alarm reporting.
Network planning
RMON gives network managers the ability to set up automatic histories,
which the RMON agent collects over a period of time, providing trending data
on such basic statistics as utilization, collisions, and so forth. Using network
management application such as Optivity, network managers can retrieve
histories to understand network usage patterns. Because RMON automates
this data collection and provides better data to the planning process, the
process is easier and the outcome more accurate.
Centralized monitoring of remote sites
RMON provides the data needed to monitor remote sites from a central
location. This enables network managers to gather and analyze network data
from remote sites and solve common network problems, thus avoiding the
expense of traveling to the remote locations to resolve problems.
Network problem solving
RMON gives network managers information they need to detect, isolate,
diagnose, and reporting potential and actual network problems before they
escalate to crisis situations. For example, the Ethernet DCM can identify the
hosts on a network that generate the most traffic or errors.
The RMON Architecture
Bay Networks implementation of RMON consists of the BayStack AN or
BayStack ANH baseboard, a data collection module (DCM), data collection
middleware (DCMMW), and the DCM Flash memory module (F
igure 2-2.)
