Creating a Flow Mirror flow definition

This procedure provides step-by-step instructions for configuring a Mirror flow definition. For more
specific example procedures, refer to
1. Right-click a switch and select Fabric Vision > Flow > Add.
2. Enter a name for the flow definition in the Name field.
3. Clear the Monitor check box.
4. Select Mirror check box.

Flow Mirror is only supported on 16 Gbps-capable FC devices.
Flow Mirror is only supported on F_Ports or F_Port trunks operating at 8 Gbps or less.
Flow Generator flows can only be mirrored at the ingress port.
Flow Mirror requires a Fabric Vision license on the device where you are creating a mirrored
flow.
Flow Mirror only supports one active flow per device.
Flow Mirroring is supported in Virtual Fabric and non-Virtual Fabric mode.
Flow Mirror is not supported in Access Gateway mode or across a Fibre Channel Routing (FCR)
backbone fabric.
Flow Mirror flows can only mirror up to 256 frames (maximum) to the embedded port (CPU) per
second. If a higher number of frames match the mirror criteria within a second, only the first
256 frames are mirrored. For chassis, 5120 frames are stored. For switches, 1280 frames are
stored.
Flow creation is not allowed if Advanced Performance Monitor (APM) or Port Mirroring is
enabled. Similarly, APM and Port Mirroring-related operations are not be allowed if any flow
(active or defined) is present on the switch.
The Add Flow Definition dialog box displays with the following criteria and flow identifiers
pre-populated:
•
Feature — Monitor
•
Direction — Bidirectional
•
Target Switch — Name of the target switch
•
Source Device — * (an asterisk allows you to use any port)
•
Destination Device — * (an asterisk allows you to use any port)
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.
