You can configure ESX Server 3.5 (VMware) using the following steps:
Make sure the VMkernel TCP/IP stack is properly configured and that a VMkernel virtual interface
(vmknic) exists on the network where your collector is located.
The ESX Server implementation of NetFlow uses the ESX Server TCP/IP stack to send NetFlow packets in the network.
vmkload_mod netflow
vmkload_mod -l | grep netflow
Use the application called net-netflow for the remaining configuration steps. The application is located
in /usr/lib/vmware/bin/
and takes multiple parameters, as shown in the following example:
net-netflow -e {VSWITCHNAME}
{NETFLOW_SERVER_IP}:{NETFLOW_SERVER_LISTENER_PORT}
