Netflow Sampler doesn't work.

Hello community!

 

I am trying to configure a Netflow sampler with flexible Netflow in a 3850 Switch, my configuration is as follow:

flow record NetFlow-to-Analyzer
match ipv4 source address
match ipv4 destination address
match ipv4 protocol
match transport source-port
match transport destination-port
match ipv4 tos
match interface input
collect interface output
collect counter bytes long
collect counter packets long
!
!
flow exporter Diana
destination 10.111.1.94
source Vlan300
transport udp 9996
!
!
flow monitor NetFlow-Analyzer
exporter Diana
cache timeout active 60
record NetFlow-to-Analyzer
!
sampler SAMPLER-1
mode random 1 out-of 2

Interface Te1/1/1 (This is a trunk interface)

flow ip monitor NetFlow-Analyzer sampler SAMPLER-1 input

 

The Netflow configuration works OK, I am using Netflow Analyzer in my PC and I am receiving all the flows, but the sampler is not working, In fact I can't see statitics from the "show sampler" output. And I need this work, do you have any recommendation? Am I doing something wrong in my configuration?.
