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
• 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 Fabric OS Administrator's Guide.
NOTES
This command requires either a Fabric Vision license or a Fabric Watch and an Advanced Performance
Monitoring licenses.
The Port Mirror or Advanced Performance Monitor with Flow Vision are mutually exclusive.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
