2 Do you want to use a single filter or combine multiple filters from
the list?
Multiple Filter Mode. If you want to combine multiple filters
from the list, enable the Multiple Filter Mode option. Then,
check the boxes corresponding to the filters you want to use.
Multiple filter mode allows you to select two or more display
filters to apply in the Sniffer window. Select options from the
list of available filters to create a single filter using
combinations of existing filters. If you select a parent
category, all the filters within the category are selected
automatically. When the parent category is unselected, all
the filters within the category are deselected.
NOTE: When the combination filter is applied, it acts as an
“OR” between the selected filters. Because of this, Multiple
Filter Mode may return unexpected results when using Exclude
filters (filters set to remove matching traffic). See Multiple
Filter Mode and Exclude Filters on page 176 for details.
Single Filter Mode. If you are using only a single filter, leave
Single Filter Mode enabled and check the box corresponding to
the filter you want to use.
