Nexus 9k Netflow configuration example
Hello,
Does anyone happen to have an example Nexus 9k which has been configured and is displaying netflow properly? I was able to get the cflow packets to our collector but the packets are being discarded because we are missing the type=4 field for protocol. Based on Ciscos documentation and the example 3750 netflow config that LM provides in their netflow doc, we have that protocol field set but we are still seeing the error, so any example config would help us.
Thank you
