If you need to feed same sFlow, Netflow or IPFIX traffic to multiple consumers and your switch or router does not support multiple targets, we suggest using external tool for it. We have good experience with samplicator.
You can install it this way.
Install build dependencies:
apt-get install -y automake gcc
cd /tmp git clone https://github.com/sleinen/samplicator.git cd samplicator ./autogen.sh ./configure make
Copy binary to /opt:
cp samplicate /opt
And start it:
/opt/samplicate -p 2056 18.104.22.168/2055 22.214.171.124/2055
It will receive messages on port 2056 on local machine and forward to:
