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?.
DNA-Testing#show sampler Sampler SAMPLER-1: Export ID: 6 Description: User defined Type: random Rate: 1 out of 2 Samples: 0 Requests: 0 Users (2): flow monitor NetFlow-Analyzer (ip,Te1/1/1,Input) 0 out of 0 SAMPLER-1 0 out of 0
My Switch version is:
