Flow Mirror limitations
•
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.
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
“Flow Mirror example procedures”
1. Right-click a switch and select Fabric Vision > Flow > Add.
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)
2. Enter a name 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.
3. Clear the Monitor check box.
4. Select Mirror check box.
