Capture Filters Capture Triggers Capturing Packets You can define filters to capture only the particular packets you need, so that you can focus on the data necessary for troubleshooting network problems. When you apply a filter to the capture process it is called a capture filter. A capture filter allows only certain frames to be saved in the capture buffer. For a description of how to define a filter, see Defining Filters and Triggers on page 219. The trigger feature allows you to start and stop captures based on date and time, alarms, and specific network events. Use triggers to capture data while Sniffer Portable Professional is unattended, such as on off-hours or weekends, or to start captures when specific events occur, such as alarm conditions. For a description of how to define a capture trigger, see Defining Triggers on page 242. User’s Guide 129
