This chapter provides guidelines and other key information about how to
set up roving analysis in your system, including the following tasks:
■
Display roving analysis configuration
■
Add and remove analyzer
■
Start and stop monitoring
Roving analysis is the mirroring of traffic on one port to another port of
the same media type.
■
The port being monitored is called the monitor port.
■
The port that receives the mirrored traffic is called the analyzer port.
The analyzer port typically has a network analyzer or RMON probe
attached through which you can watch the network traffic.
Use roving analysis to monitor Fast Ethernet, Gigabit Ethernet, or Fiber
Distributed Data Interface (FDDI) port traffic for network management
and troubleshooting purposes. You use the Administration Console to
choose any network segment that is attached to a system and monitor its
activity.
You can monitor a designated roving analysis port to:
■
Analyze traffic loads on each segment so that you can continually
optimize your network loads by moving network segments
■
Troubleshoot network problems (for example, to find out why a
particular segment has so much traffic)
For more information about implementing roving analysis on your
network, see the Implementation Guide for your system.
