7.8.2.2. Search result
At the top-right of the dialog you will find an indication of the number of currently marked packets and the
number of currently unmarked packets.
When the search is performed (Search button clicked), new packets may be marked or marked packets
may be unmarked (depending on the chosen options). These changes will be reflected in the current
number of marked and unmarked packets.
Note that you can easily examine the marked packets using the buttons to get to the previous and next
marked packet in the toolbar of the Packet View and using the menu functions in the 'Search' menu of the
Recorder window to go to the first or last marked packet.
7.8.2.3. Set selection, Search button and Close button
At the bottom of the dialog you will find the Search button, Close button and the Include packets defined
in: box.
Search
When clicking the Search button, the search is performed. Packets and events may be marked or
unmarked and the number of currently marked and currently unmarked packets will reflect the result
(top-right of dialog).
Close
When clicking the Close button, the dialog will quit without doing the search. No packets will be marked or
unmarked and the number of currently marked and currently unmarked packets will not change.
Include packets defined in:
Here you can type in a set name or any boolean combination of the four sets. All packets that are included
in the search and that fit the Set or combination of Sets, will be marked or unmarked (depending on the
chosen option). In the example above, all packets that fit the description of SetA will be marked, others
will be unmarked.
The set names that can be used are 'seta', 'setb', 'setc' and 'setc'. The names are not case sensitive, thus
'SetA' is valid too. You can also use just 'a', 'b', 'c' or 'd' (or 'A', 'B' etc.) for the set names. The Boolean
operators are 'not', 'and' and 'or'. But they may be substituted by the characters '!', '&' and '|' respectively.
Parenthesis may be used to group the Boolean operations.
Some examples of valid expressions are:
setc
NOT SETB
(seta or setb) and not setd
!SetA & (SetC | SetB)
a
C or D
Note that a red cross will be displayed before the boolean expression when there is an error in the
expression.
7.8.2.4. Packet Sets
Up to four Sets (SetA, SetB, SetC and SetD) can be used for the packet search. A Set defines a subset of
all asynchronous and isochronous packets by specifying packet types, packet speeds, packet
acknowledges, and optionally value conditions for one or more header and or data fields.
A packet is said to 'fit' the Set if all specified conditions are met. Thus, when the packet is of the specified
type, and the packet is of the specified speed, and the packet is acknowledged by the specified
acknowledge, and the optional header-field and data-field conditions are met, then the packet 'fits' the Set.
A Set page has the following parts:
· Primary Packets or Phy Packets selection
·
Primary Packets box to select primary types
· Packet Speeds box to select which packet speeds are included
·
Acknowledge box to select which acknowledge should follow the packet
·
Header Values box to specify optional header field conditions
