7.4 Creating A FilterSet That Captures
Specific VCCs
While you’re monitoring real-time statistics, you may notice one or more VCCs
that require closer analysis. In this case, you can define a filterset from the real-
time statistics window that includes only those VCCs, then initiate a new capture
using the filterset. (Alternatively, you can save the filterset for later use.)
Choose Create Filter from the Tools menu to
define the new filter. Then:
•
Specify a name for the filterset in the Name
field.
•
Mark Capture Idle Cells to capture idle cells
(in addition to those for the VCC(s)
specified). This is useful, for example to
determine how much of the bandwidth is used
for idle-cell traffic. If you mark this box,
622Vu Advisor defines a buffer in the filterset
that’s dedicated to storing idle cells.
By default, a cell is considered idle if it has
zeros in every bit position of the first five
header fields. If you want to capture idle cells but change the definition of an
idle cell, first save the filterset by clicking OK, then edit it using 622Vu
Advisor’s standard filterset editor, detailed in Chapter 8.
•
Mark Wrap All Buffers if you want to wrap each buffer when it’s full,
reusing each buffer continually until the capture is stopped. See page 140 for
more information about wrapping buffers.
•
In the VCC area, select each VCC you want to capture when you use the
new filterset.
Click OK when you’re through. 622Vu Advisor
asks if you want to launch the new capture
immediately (which will automatically stop any
active real-time statistics processing). Click Yes to
start a new capture using the filterset you just
defined; No to not start the capture and to save the filterset for future use.
