You can filter the traffic to be monitored, using the monitor filter.
The filter conditions are configured using the filter editor. You need to configure monitor filters for each interface.
When the monitor filter is applied, all the Monitor windows of the selected interface will be influenced except for the following ones:

• "MAC Frame Numbers by Frame Size" Traffic window
• "MAC Error Frames" Traffic window
• MAC Address Table
• IP Address Table
• MAC - IP Address Table
• "TCP Status Information" window
