ip flow monitor
To enable a Flexible NetFlow flow monitor for IPv4 traffic that the controller is receiving, use the ip flow
monitor command in interface configuration mode. To disable a flow monitor, use the no form of this
command.

Usage Guidelines
Before you can apply a flow monitor to an interface with the ip flow monitor command, you must have
already created the flow monitor using the flow monitor global configuration command.
already created the flow monitor using the flow monitor global configuration command.
When you add a sampler to a flow monitor, only packets that are selected by the named sampler will be entered
into the cache to form flows. Each use of a sampler causes separate statistics to be stored for that usage.

You cannot add a sampler to a flow monitor after the flow monitor has been enabled on the interface. You
must first remove the flow monitor from the interface and then enable the same flow monitor with a sampler.
must first remove the flow monitor from the interface and then enable the same flow monitor with a sampler.
The statistics for each flow must be scaled to give the expected true usage. For example, with a 1 in 100
sampler it is expected that the packet and byte counters will have to be multiplied by 100.
