A network engineer is asked to configure NetFlow to sample one of every 100 packets on a router’s
fa0/0 interface. Which configuration enables sampling, assuming that NetFlow is already configured
and running on the router’s fa0/0 interface?

A.
flow-sampler-map flow1
mode random one-out-of 100
interface fas0/0
flow-sampler flow1
B.
flow monitor flow1
mode random one-out-of 100
interface fas0/0
ip flow monitor flow1
C.
flow-sampler-map flow1
one-out-of 100
interface fas0/0
flow-sampler flow1
D.
ip flow-export source fas0/0 one-out-of 100
Examples
The following example shows how to create and enable a random sampler map for random sampled (ingress) NetFlow accounting with CEF switching on Ethernet interface 0/0:
Router(config)# flow-sampler-map my-map
Router(config-sampler)# mode random one-out-of 100
Router(config-sampler)# interface ethernet 0/0
Router(config-if)# flow-sampler my-map
