This chapter provides key information about how to configure and use
roving analysis, including the following tasks:
■
Display roving analysis configuration
■
Add and remove monitor and analyzer ports
■
Start and stop monitoring activity
Roving analysis is the mirroring of traffic from 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 or Gigabit Ethernet port
traffic for network management and troubleshooting purposes. You use
the Administration Console to choose any network segment that is
attached to a module 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 using roving analysis, see the Switch 4007
Implementation Guide .
The Switch 4007 software and management interfaces are built from
CoreBuilder
® 9000 switch technology. In Switch 4007 software
releases 3.0.0 and 3.0.5, the prompts and displays in all interfaces may
indicate this heritage.
