how to define sampling rate in netflow of cisco ISR4431

[atmaram.sahu]

Hi,

I have configured netflow on cisco ISR4431 but not getting anyoption to define sampling rate. looks like bydefault it is running @ 1/1 packet sampling.

Below are the configuration I have done...

Please suggest how to define sampling rate...

cisco ISR4431
Cisco IOS XE Software, Version 16.06.04

flow exporter EXPORTER1
destination x.x.x.x
source GigabitEthernet0/0/2
transport udp 5000

flow monitor MONITOR1
exporter EXPORTER1
cache timeout active 60
record netflow-original
flowspec

int GigabitEthernet0/0/2
ip flow monitor MONITOR1 input

Thanks,

Hello,

can you configure a flow sampler map ?

ISR4431#configure terminal

ISR4431(config)#flow-sampler-map sampler-map-name

ISR4431(config-sampler)#mode random one-out-of sampling-rate
