flow --help
Description Use this command to perform the following functions:
• Create a flow
• Activate or deactivate features for a flow
• Clear the data collected for a particular feature of a flow
• Change the control parameters for a feature or a flow
• Modify the definition of the predefined Analytics VTAP flow
• Display the flow statistics
• Delete a flow
Each of these functions is documented in a separate section that includes function, synopsis, description,
operands, and examples.
A flow is a set of related Fibre Channel (FC) frames or packets that share similar traits, such as an ingress port,
egress port, or frame options that can uniquely differentiate one set of related frames or packets from a different
set of frames. A flow is defined by a combination of ingress port, egress port, source device, and destination device
parameters. Flow Vision supports Flow Monitor, Flow Generator, and Flow Mirror features to monitor, simulate,
and capture the network traffic respectively. You can create up to 512 flows on Brocade director and 128 flow on
switch-based system. For more information on Flow Vision, refer to the Flow Vision Administrator's Guide.
