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 1129" for details on frame types).
• Direction — A direction is implicitly defined from an ingress port to an egress port, or a source
device to a destination device. For example, source device=x, destination device=y indicates
traffic flowing from x to y. The bidirectional option causes the flow definition to be monitored in
both directions.
//Note that currently all graphics reference the FOS cli parameters. All graphics

Figure 495 illustrates how the frame and port parameters apply to a flow.
