Working with Nexus 1000v, 4.0(4)SV1(1)

I am having difficulties in integrating the NTA 3.5 SP2 with Nexus 1000v, from the packet capture on NTA machine, i could see there is incoming UDP traffic to port 2025. However the netflow data was not processed by the NTA. I have enabled the interface on 1000V as netflow source from the NTA web page (when i check the box next to the interface in the netflow source page, i found they are in grey colour).

My 1000V VSM configuration is as follow:

===============

flow exporter Orion
description Orion NTA 3.5 SP2
destination 1.2.3.4
dscp 2
source mgmt 0
transport udp 2025
version 5
option exporter-stats timeout 1200
template data timeout 1200
exit

flow monitor OrionFM
description Orion Flow Monitor
exporter Orion
record netflow-original
exit

port-profile vlan123
ip flow monitor OrionFM input
ip flow monitor OrionFM output

================

Have i missed anything in the configuration? Thank you!

Hi Patrick,

by default NTA listens on a port 2055 and in your case port 2025 is used.

You can make NTA listen on a multiply ports, though. To do that, please navigate to NetFlow Settings page and Edit collector settings as shown on a screenshot.

thanks
