SETTING UP THE SYSTEM FOR

 

 

ROVING 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

Roving analysis is the monitoring of Ethernet port traffic for network

Analysis

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:

1Select an Ethernet port to which you want to attach the network analyzer.

2Select 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
