Flow Vision features
Flow Vision has three features: Flow Monitor, Flow Generator, and Flow Mirror. The following
sections describe each feature and provide links to a more detailed explanation and to step-by-step
procedures for each feature.
Flow Monitor
Flow Monitor provides flow monitoring and the gathering of frame statistics for fabric application
flows, including the ability to learn (discover) flows automatically. For a more detailed description,
refer to
“Flow Monitor” on page 1737". For a general step-by-step procedure and example
procedures, refer to “Creating a Flow Monitor flow definition” on page 1739" and “Flow Monitor
example procedures” on page 1752".
To monitor a Flow Monitor, refer to “Monitoring a Flow Monitor flow” on page 1748".
Flow Generator
Flow Generator simulates and generates test-load traffic in specific flows; this allows you to
validate hardware components, connectivity, and verify performance. For a more detailed
description, refer to
“Flow Generator” on page 1776". For a general step-by-step procedure and
example procedures, refer to “Creating a Flow Generator flow definition” on page 1780" and “Flow
Generator example procedures” on page 1786".
To monitor a Flow Generator, refer to “Monitoring a Flow Generator flow” on page 1783".
Flow Mirror
Flow Mirror provides the ability to non-disruptively create copies of application flow frames that can
be captured for deeper analysis. For a more detailed description, refer to
“Flow Mirror” on
page 1788". For a general step-by-step procedure and example procedures, refer to “Creating a
Flow Mirror flow definition” on page 1790" and “Flow Mirror example procedures” on page 1796".
To monitor a Flow Mirror, refer to “Monitoring a Flow Mirror flow” on page 1793".
Flow Vision flows
A flow is a set of FC frames or packets that share similar traits, such as an ingress port or egress
port identifier or any other data that can be used to differentiate one set of related frames or
packets from a different set. You specify the following parameters as part of the flow definition:
• Port parameter — Also called the Point of Interest, or where the data you want to examine is
from. This consists of an ingress port or an egress port. You can specify the ingress port or the
egress port, but not both in a flow definition.
• Frame parameters — These include the following parameters: source device identifier (port ID
or WWN), destination device identifier (port address or WWN), LUN, or frame type. At least one
frame parameter must be present to define a flow (refer to
“Supported frame type parameters”
on page 1729" for details on frame types).
