sFlow and NetFlow and hardware acceleration
NP7, NP7Lite, NP6, NP6XLite, and NP6Lite offloading is supported when you configure NetFlow for interfaces connected to NP7, NP7Lite, NP6, NP6XLite, or NP6Lite processors. Offloading of other sessions is not affected by configuring NetFlow. Full NetFlow is supported through the information maintained in the firewall session.
Configuring sFlow on any interface disables all NP7, NP7Lite, NP6, NP6XLite, or NP6Lite offloading for all traffic on that interface.
