Do we really need to enable NetFlow on all physical interfaces connected to servers or endpoint firewalls in case SVI (L3 interface ) has NetFlow configuration.
We are not getting NetFlow traffic details properly details but configured on the SVI (Layer 3 interface)
Do we really need to enable NetFlow on the all the physical interfaces if NetFlow is already configured on the SVI (Layer 3 interface), or is SVI-level NetFlow sufficient for our monitoring requirement?
