5. Select one of the following options:
•
CPU Mirroring
Select to mirror traffic to the switch CPU, which enables you perform debugging without
disturbing existing connections. By default, CPU Mirroring is enabled.
•
Local Flow Mirror
Select to mirror traffic to an unoccupied, loopback, or mirror port on the selected target
switch, which enables you to mirror a flow to a specific port, which is present on the same
physical switch on which you defined the flow.
LFM mirrored data can then be analyzed through an external Analyzer/Frame sniffer
connected to the port. LFM requires that a loopback SFP be plugged in at the other end of
the analyzer, or on the port configured as a mirror port.
Note that if you select an unoccupied or loopback port, the Management application first
reconfigures the port as a mirror port, and then creates the flow.
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. Change the target switch for the flow definition by clicking the ellipsis button to the right of the
Target Switch field.
The Select Switch dialog box displays. To manually set the Target Switch, refer to “Selecting the
target switch from a list of Fabric Vision-capable switches” on page 1144".

select a port from the list.

When you enter a port ID or WWN in the Source or Destination fields, a port information field
displays beneath with the port label based on your topology layout settings (refer to
“Changing
the port label” on page 386"). If you enter an asterisk (*) or no value in the Source or
Destination fields, this field remains blank.
