1.
Display filters
allow a user to look at a subset of captured data without affecting the capture content.
Frames matching the filter criteria appear in the
Frame Display
; frames not matching the criteria
will not appear.
2.
Connection filters
Two options are available.
a. A Bluetooth connection: Displays only the frames associated with a Classic
Bluetooth
link or a
Bluetooth
low energy access address. A new
Frame Display
will open showing only the
protocol tabs, frames, summary, and events associated with that particular
Bluetooth
connection.
b. A specific wireless or wired technology. Displays all of the frames associated with:
l
Classic
Bluetooth
l
Bluetooth
low energy
l
802.11
l
HCI
A new Frame Display will open showing only the protocol tabs, frames, summary and events
associated with the selected technology.
4.3.1.13.1 Display Filters
A display filter looks at frames that have already been captured. It looks at every frame in the capture buffer
and displays those that match the filter criteria. Frames that do not match the filter criteria are not displayed.
Display filters allow a user to look at a subset of captured data without affecting the capture content. There
are three general classes of display filters:
l
Protocol Filters
l
Named Filters
l
Quick Filter
Protocol Filters
Protocol filters test for the existence of a specific single layer. The system creates a protocol filter for each
decoder that is loaded if that layer is encountered in a capture session.
There are also three special purpose filters that are treated as protocol filters:
l
All Frames with Errors
l
All Frames with Bookmarks
l
All Special Information Nodes
Named Filters
l
Named filters test for anything other than simple single layer existence. Named filters can be constructed
that test for the existence of multiple layers, field values in layers, frame sizes, etc., as well as
combinations of those things. Named filters are persistent across sessions.
l
Named filters are user-defined. User-defined filters persist in a template file. User defined filters can be
deleted.
