The Add Flow Definition dialog box displays with the following criteria and flow identifiers
pre-populated:
•
Feature — Monitor
•
Direction — Bidirectional
•
Source Device — Source identifier (0x040100)
•
Destination Device — * (an asterisk allows you to use any port)
•
Ingress port — SIM-Port number (1/1)
3. Enter a name (flowcase1) for the flow definition in the Name field.
The name cannot be over 20 characters and can only include alphanumeric characters or
underscores.
NOTE
For a physical switch, the name must be unique. However, for logical switches, the name does
not have to be unique.
4. Clear the Monitor check box.
5. Select the Generator check box.
The Source to Destination option is selected by default.
6. Select the Persist over switch reboots check box to persist this flow definition over reboots.
7. Select the Activate all selected features check box to immediately activate the flow after
creation.
8. Enter the address or WWN of the destination SIM-Port in the Destination field.
9. Click OK to save the flow definition.
When the flow definition activates, the Flow Vision dialog box displays with the new flow
selected (highlighted) in the Flow Definitions table. To review the sub-flow data for the selected
flow, refer to
“Monitoring a Flow Generator flow” on page 1184". To configure the frame
payload size and pattern for the flow, refer to “Customizing Flow Generator flows” on
page 1183".
Integrating Flow Generator with Flow Monitor
Flow Generator flows can be monitored using Flow Monitor. For example, you can use a
combination of Flow Generator flows and Flow Monitor flows to verify per-flow throughput at an
ingress or egress port. This can be useful when more than one Flow Generator flow shares the
same ingress or egress port. To do this, you must create a flow using both the Flow Generator and
Flow Monitor features that share the ingress or egress port. The following example illustrates this
integration.
To create a generator flow and a monitor flow, complete the following steps.
1. Create two SIM-Ports ( “Enabling SIM-Port mode” on page 1180").
In this example, SIM-Port 1/1 is the source port and SIM-Port 1/2 is the destination device.
2. Right-click an initiator SIM-Port in the Product List and select Fabric Vision > Flow > Add.
