Capture Buffer Size

Specified via allocated memory or maximum number of packets. Incoming frame data
may be recorded at wire rate, filtered to reduce the amount of information, and start/
stopped in response to a variety of trigger conditions.

Frame capture, namely the recording of frame contents by the receiving SmartBits card, is
stopped upon user request or when the capture buffer has been depleted. The maximum
number of frames that can be captured depends on frame size and the available buffer size.
