In configuring a router to send NetFlow to Cascade, an important point to consider is:

Ensuring the interface of the Cascade Profiler is on the same subnet as the router, as NetFlow is not routable.

Using the “tcp/(n) + 1” port numbering scheme to ensure this router’s NetFlow is unique from all other routers.

Ensuring the router has IP connectivity to the Cascade Gateway.

Ensuring the interface of the Cascade Gateway is on the same subnet as the router, as NetFlow is not routable.

Using the “udp/(n) + 1” port numbering scheme to ensure this router’s NetFlow is unique from all other routers.
