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 using a standard cap format. The classification of the traffic portion to
be captured is based on L4 attributes. The captured information is sent to a specified FTP destination.
The FTP transaction is done online on SCE2000 platforms.
The following flow-capture operations are available:
start—Starts recording.
stop—Stops recording.
Note that traffic can be captured only when an application is loaded.
To perform a flow capture, follow these steps:
1. (Optional) Configure limits to the flow-capture operation using the flow-capture controllers
command. Limits prevent a negative impact on traffic processing.
You may skip this step and use the default controller values.
2. Configure an appropriate recording rule using the traffic-rule command. Assign the flow-capture
action to the rule (see traffic-rule).
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.
filename Destination (FTP site path) where the cap file should be created, in the
format: ftp://username:password@ip_address/path/filename. (Do not
include the ".cap" file extension; it is appended automatically.)
stop Stops recording.
