4. In the Source area, indicate whether to consider traffic captured on Channel
1, Channel 2, or both.
5. Mark Search Backwards to begin searching for cells/PDUs to include in the
subset at the end of the capture file; otherwise (with this box unmarked) the
system starts at the beginning of the file.
6. If you’re searching for an ASCII value, indicate whether to Match Case or
not. Leave this box blank for a non-case-sensitive search.
7. If you want to treat the Find What and/or VCC values as a bit-match pattern,
mark the Use Search String as Bit-AND Mask box. With this box marked,
622Vu Advisor interprets the Find What and/or VCC values as a bit-match
pattern, returning all cells/PDUs that match any of the ON bits in the mask.
For example, if you specify a hex 03 (binary 0000 0011) in the search string,
fixed at offset 15, 622Vu Advisor looks for traffic whose payload has either
of the low-order two bits set.
8. Optionally, mark the Select Cells/PDUs NOT Matching Search Criteria
box to toggle between selecting values that match or don’t match the other
specifications. With this box marked, the select/reject decision that’s made
by taking all the other criteria into account is reversed at the very end of the
decision-making process; any cells or PDUs that would normally be rejected
from the subset are accepted, and any cells/PDUs that would normally be
accepted are rejected.
9. The Search at Fixed Offset field applies if you’re searching for a string in
the payload. It allows you to specify an offset from the beginning of the
payload where you want to begin the search. Valid offsets are in the range
1–48 for a cell-by-cell search; 1–65,535 for a PDU search. If you leave this
field blank, 622Vu Advisor searches the entire payload.
10. The Search Index Range field lets you limit the search to a particular range
of cells or PDUs, identified by the number displayed to the left of each
cell/PDU in the capture-file display. Specify a starting (i.e., low) and/or an
ending (i.e., high) number to identify the range you want to search. These
default, respectively, to the first and last cells in the capture file.
11. The Search Time Range field lets you limit the search to cells/PDUs
captured during a specific time period. Specify the from (left) and to (right)
times using an hour:minute:second format, with an optional 9 decimal
positions to the right of the seconds field: hh:mm:ss.nnnnnnnnn
Use the Clear and Reset buttons at the bottom of the form to set all values to
their default settings, or to redisplay the last saved set of values, respectively.
(The OK button saves values.)
