The Filters section defines filters that will appear in the predefined filter section. This is mostly a convenience for your users because they can very quickly select a predefined filter and they don't have to think about how to define it.
The format is:
[filter name],[location in tree],[compound filter],Include|Exclude,[bpf string]
where:
[filter name] is the name that will appear in the filters window.
[location in tree] is where you want it to appear in the tree that is used to organize filters in the predefined window.
[compound filter] is the name of the compound filter that this filter is a part of (note that compound filter is rarely used in predefined filters).
Include|Exclude defines whether the filter should include data that matches the filter or exclude it.
[bpf string] is the filter string in BPF format.
For information on creating filter strings using BPF, see the online Help for the protocol analyzer product.
