Hints and Tips for Using Filters

•Remember to load the Capture filter on the module before you start capture.

•If you want to look at captured data in many different ways, use display filters rather than capture filters. Capture large blocks of unfiltered data and look at different subsets of the data by using a variety of display filters.

•Use the Template Description button to find out the exact mask and logical operations in a filter template.

•Use conversations for capturing or displaying station-to-station or router-to- router activity.

•Always attach a description to a filter you are saving with the Description menu.

•To see which capture filter is associated with the current resource, choose Active TSP and Capture Filter from the Module menu. The capture filter name is also displayed in the status bar in Detail view.

•In the Filter Design window, make sure that the templates you want in the filter are displayed in the Template Combination box. If a template is not displayed in the Template Combination box, it is not part of the filter to be applied.

•Be sure to click the Apply Conversation to Template check box to include a con- versation as part of your filter.

•AND operations narrow the search results and are typically used between tem- plates that define masks for different offsets and lengths. Using AND opera- tions between filter templates that define masks for the same offsets and lengths will result in a pattern-conflict warning message.

•OR operations expand the search results and are useful between filter templates that define masks for the same offsets and lengths.

•To edit a statement in the Filter States Design window, double-click on the statement.

•Use the right mouse button to learn about the options available for any state- ment in a filter. You can immediately see what options are possible depending on what type of statement is selected.

• Use the	button to add states or statements to the Filter States Design win-
dow.
