Filter Expression Language
Protocol Analyzer lets you specify a filter expression directly, rather than
using the component windows.
This approach gives you complete control over the filter expression and
lets you create filters that cannot be specified through the component
windows. For example, you can specify logical ORs to connect Host and
Protocol filters or include some protocols while excluding others.
A complete description of the filter expression language begins on
page 376.
