Hi Johan,

Check out the Q & A document posted here: http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps12995/qa_c67-728348.pdf

Energy Efficiency Chapter (page 8) gives more details about hibernation modes.

Intelligent Services (page 14) tells you more about NetFlow Lite.

Thanks,
Pradeep Parmar
