Multiple netflow destinations (Cisco Nexus OS)


Nexus OS configuration to add multiple destination/server to collect your netflow statistics

flow exporter server1
  destination 128.100.1.187
  transport udp 2055
  source Vlan250
  version 9
!
flow exporter server2
  destination 10.10.125.250
  transport udp 2055
  source Vlan250
  version 9
!
sampler netflow-sampler
  mode 1 out-of 10
!
flow monitor NETFLOW
  record netflow-original
  exporter server1
  exporter server2
!
!
!
!
interface vlan 100
      ip flow monitor NETFLOW input sampler netflow-sampler
!
!

If you would like to added the 2nd server in after you have 1st production netflow server configured. You will need to move all ip flow monitor configuration from all your applied interface before you can modify the "flow monitor" command.

You can use "show flow interface" to find out which interface are configured to be tracked.
