6.1 Starting a New Capture
After you request New Capture
processing, 622Vu Advisor displays
the 622Vu undercradle (right). The
622Vu undercradle is identified by a
descriptive icon (
), followed by
the name of the device and a number
(always 1).
Select the device you want from the
list, then click Next.
You’ll only see those devices that
are available for use currently. If the device is already performing RAM-
intensive activity (such as a capture), it won’t appear in the list. If you expect to
see a device that isn’t here, click the Refresh button to reevaluate its status.
After making your device selection,
622Vu Advisor prompts for any
filtering you want to use. By
default, 622Vu Advisor captures all
non-idle cells coming in over both
channels. The resulting capture files
can become very large, so 622Vu
Advisor lets you filter captures, to
limit their size. The form shown to
the right lets you post-filter the
capture. Note that this filter
operates on an existing capture, it
does not affect how cells are
captured.
You can filter captures based on VCC, IP address, decode, or incoming channel.
You can also use filters to control the way in which the traffic is captured (using
a single buffer that wraps, using multiple buffers that don’t wrap, etc.). Refer to
Chapter 8 if you’re not familiar with filtering.
As the first step to filtering a capture, you must define (i.e., establish) the filtering
criteria to use. There are three ways to do this: through 622Vu Advisor’s
standard filterset processor (detailed in Chapter 8), while monitoring real-time
statistics (detailed in Chapter 7), or using the capture facility’s filterset wizard
(described in this chapter). In the latter two cases (real-time stats and filterset
wizard), you have the option of saving the filter definition, or discarding it after a
