Cisco SCE 8000 CLI Command Reference

Chapter 2 CLI Command Reference

flow-capture

Tip You must use the traffic-rule command to define the recording rule. You cannot use the

flow-filter command.

3. Start the actual capture. The capture will not start if a valid recording rule has not been defined.

Use the flow-capture start command.

4. (Optional) Stop the capture.

Use the flow-capture stop command.

If you do not stop the flow capture, it will stop when the maximum duration or capacity has been

reached.

At any point, you can use the show interface linecard flow-capture command to display the flow-

capture status, including whether flow capture is currently recording or is stopped, the capacity already

used, and the number of packets recorded.

Authorization: admin

Examples The following examples show how to use this command. All examples show output for an SCE 8000

with two SCE 8000-SCM modules installed.

Example 1

The following example shows how to perform all the steps in a flow capture:

1. Define the limits (flow-capture controllers max-l4-payload-length and flow-capture controllers

time).

2. Define a counter to be assigned to the traffic rule. (Optional)

3. Define the recording traffic rule (traffic-rule with action flow-capture option).

4. Start the capture (flow-capture start).

(The show command shows that recording is in progress.)

5. Stop the capture (flow-capture stop).
