OVING ANALYSIS
This chapter describes how to set up the SuperStack™ II Switch 2200
system for roving analysis. With roving analysis, you can monitor Ethernet
port activity either locally or remotely using a network analyzer attached to
the system.
About Roving
Analysis
Roving analysis is the monitoring of Ethernet port traffic for network
management purposes. The Administration Console allows you to choose
any Ethernet network segment attached to a Switch 2200 system and
monitor its activity using a network analyzer (also called a “probe” or
“sniffer”).You can monitor port activity locally (when the analyzer and the
port are attached to the same Switch 2200 system) or remotely (when the
analyzer and the port are on different systems).
You can monitor a 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 there is so
much traffic on a particular segment)
When you set up an Ethernet port to analyze, port data that is switched
over Ethernet is copied and forwarded to the port on which the network
analyzer is attached — without disrupting the regular processing of the
packets.
To enable the monitoring of ports on a Switch 2200, take these steps:
1 Select an Ethernet port to which you want to attach the network analyzer.
2 Select the Ethernet port that you want to monitor (either local or remote). If
the port is remote, you must configure it from the Switch 2200 on which
