I don't know why, but dna instead of standart netflow config with name dnacmonitor tries to make netlow exporter and netlow monitor with name 192.168.1.50 (it's VIP enterprise interface)
!NetflowConfigs
flow exporter 192.168.1.50
destination 192.168.1.50
transport udp 6007
exit
!done
!NetflowConfigs
!done
