Command History This table includes the following release-specific history entries:
Usage Guidelines The flow capture is a useful debugging capability that captures packets from the traffic stream in real
time and stores them for later analysis. The classification of the traffic portion to be captured is based
on L4 attributes.
The portion of traffic that is captured does not receive service (is not processed by the application).
Therefore it is important to control the capturing scenario so that service is not negatively affected. This
is done by limiting certain aspects of the flow capture.
The following options are available:
• time (flow capture recording time) — The duration of the flow capture may be limited to the
specified time limit, or it may be unlimited, so that the flow capture is stopped only by executing
the explicit stop command, or when maximum file size is reached (128MB in SCE8000 platform).
• max-l4-payload-length (payload size)— The maximum number of L4 bytes captured from each
packet may be specified. This parameter relates to each packet in the traffic stream rather than
overall flow capture capacity. Using this parameter, the flow-capture throughput (in terms of
captured packets) can be increased.
Authorization: admin
duration Maximum duration for the flow capture recording time in seconds.
To specify unlimited duration, use the unlimited keyword.
length To specify unlimited payload bytes per packet, use the unlimited keyword.
