Starting Port

After you have a local or remote port configured for the network analyzer,

Monitoring

you can start monitoring port activity.

 

3Com recommends that you ALWAYS configure the analyzer port before

 

configuring the monitored ports.

To start monitoring a new port:

1From the top level of the Administration Console, enter:

analyzer start

2Press Return to select Ethernet as the port type.

3Enter the number of the Ethernet port to monitor.

4Enter the MAC address of the port to which the network analyzer is attached (the port to which the data will be forwarded).

The MAC address of the analyzer port is displayed when you configure that port, and it is also available when you display the roving analysis configurations on the Switch 2200 system to which the analyzer is attached.

See the example below for starting port monitoring:

Select port type [Ethernet]: Select port (1-16): 16

Enter the target analyzer port address: 00-80-3e-0a-3b-02

Port selection errors If your port selection is not valid, you receive one of the following messages:

Error starting monitoring - analyzer already configured on

this port

Error starting monitoring - monitoring already configured

on this port

MAC address error If the analyzer port is remote, its MAC address may not be learned on the local system and you receive the following error message:

Error starting monitoring - analyzer location unknown

CAUTION: If you receive the above message, check your analyzer port configuration before proceeding. An incorrect configuration will result in frames being continuously flooded throughout your bridged network.
