Flow Monitor examples
The following examples display how to use the Flow Monitor feature.
Monitoring LUN level statistics
A common use of flow monitors is to monitor traffic flowing from a particular ingress port to a specified
LUN.
The following example creates a flow named “lunFlow11” that monitors traffic ingressing on port 5
between device 010502 and device 030700 using LUN 4, and then displays the results of that flow.
The figure provides an illustration of what is happening in the example.

Viewing summary flow data for a specific device pair
The following example creates a Flow Monitor flow gathering statistics for frames ingressing through
port 30 between device 010000 and device 010100, and then displays the results. The point of interest
in this example is port 30; it can be an E_Port, EX_Port, or F_Port.
switch:admin> flow --create sumflow1 -feature monitor -ingrport 30 -srcdev 010000 -dstdev 010100
switch:admin> flow --show
