Command History This table includes the following release-specific history entries:

Usage Guidelines Flow capturing 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. You

can limit certain aspects of the flow capture using the following options:

• 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 an

explicit stop command or when the maximum file size is reached (128 MB on the Cisco SCE 8000

platform).

• max-l4-payload-length (payload size)—The maximum number of L4 bytes captured from each

packet may be specified. This keyword relates to each packet in the traffic stream rather than to

overall flow-capture capacity. Using this keyword, 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 Specifies the number of payload bytes per packet.

To specify unlimited payload bytes per packet, use the unlimited keyword.
