This chapter describes how to set up the 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.
Roving Analysis is the monitoring of Ethernet port traffic for network
management purposes. The Administration Console allows you to
selectively choose any Ethernet network segment attached to a LANplex
6000 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 port are attached to the same LANplex option module) or remotely
(when the analyzer and port are on different modules in the same system or
in two separate systems)
You may want to 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 LANplex, you must do the following:
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 LANplex or module (ESM
