Software Reference for SwitchBlade x3100 Series Switches (Network Management)
7.5 Remote Network Monitoring (RMON)
Performance management is the collection of traffic statistics over the interfaces (usually ports) over a specified
time period (called the interval). During this period, if the value for a certain statistic crosses a threshold value,
it is noted and a log is produced.
The SBx3112 has RMON software agents that collect and analyze data. The data collected deals mainly with
traffic flow patterns rather than the status of hardware devices. The RMON software agents support the collec-
tion of statistics and historical data for performance management purposes.
7.5.1 RMON Configuration
Figure 7-12 shows the performance management configuration for the SBx3112 switch.

7.5.1.1 Performance Management and Fault Management
An understanding of the relationship between performance management and fault management allows the user
to engineer the network to spot potential faults as well as repair actual faults efficiently.
• The goal of the Performance Management system, using RMON software agents, is to assess the overall
health of a line to spot conditions that could lead to a line fault.
