About Quick Select Filters EARLY FIELD TRIAL Chapter 6 120 Sniffer Adaptive Application Analyzer Sniffer Adaptive Application Analyzer provides centralized filter creation and management using the Mining Filtering controls at the base of the Quick Select window (Figure 6-1). Figure 6-1. Centralized Filter Creation in Sniffer Adaptive Application Analyzer Quick Select filters let you include/exclude packets matching precise combinations of network criteria, including MAC addresses, IP addresses, ports, IP protocols, pattern matches, and so on. Quick Select filters can be very simple, consisting of a single term, or very sophisticated, involving multiple terms connected by Boolean AND/ OR/NOT operators. You can also specify that specific terms be included or excluded.

EARLY FIELD TRIAL Reusable Filters with Multiple Filter Points Using Filters in the Quick Select Window Once you have created a filter from the Quick Select window, you can use (and reuse) it as a Mining filter, Source filter, Display filter, or Statistics filter. Table 6-1 summarizes the differences between each of these filter points. Figure 6-2 illustrates the Source, Mining, and Statistics filter points; refer to Applying Adaptive Display Filters on page 136 for information on using Quick Select filters as Display filters with Adaptive Session/Packet data. Table 6-1. Quick Select Window Filters Filter Type & Description How Applied? Mode? Source Filters Source Filters are applied at the network interface. They exclude packets matching specified criteria from monitoring or capture: • Monitor statistics in the Quick Select window will not include packets excluded by a source filter. This includes both the Graph panel and all Statistics panel tabs. • Postcapture analysis will not include packets excluded by a source filter. This includes both Adaptive and raw packet postcapture views. Note: Because source filters prevent matching packets from ever being seen by Sniffer Adaptive Application Analyzer, you should apply them carefully. Mining Filters Mining filters are applied when you click the Mine button to retrieve stored packet data (ASPs or raw packets) from the capture buffer. They are used to focus postcapture analysis on packet data matching specified criteria. Right-click a stream in the Navigation panel, choose Apply Source Filter, and select the filter to use as a source filter. Once you’ve applied a source filter to a stream, its entry in the Navigation panel appears with a distinctive icon when selected. Select a filter from the Mining Filtering dropdown at the base of the Quick Select window before clicking the Mine button. Alternatively, you can use the Edit Filter button in the Summary dialog box that appears after clicking Mine. Adaptive and Raw Adaptive and Raw User’s Guide 121
