 ip access-group TEST in
 ip access-group TEST out

Re the image difference, here

Re the image difference, here is a quote from the data sheet:

  • IP Base software includes advanced quality of service (QoS), rate limiting, access control lists (ACLs), Open Shortest Path First (OSPF) for routed access, and IPv6 functionality.
  • IP Services software provides a broader set of enterprise-class features, including advanced hardware-based IP Unicast and IP Multicast routing, as well as policy-based routing (PBR).

 

Re Netflow, I've never had good luck getting NetFlow from a L2/L3 switch other than a higher-end model with the hardware support - i.e.,  4500 with Netflow Feature card, 6509 or 3750X with the Netflow network service module installed. I beleive the new 2960X models also have the necessary hardware support.

 

On other switches, the SVIs do not export the flow correctly even though the IOS allows you to enter the commands. I'm told it's due to hardware limitations as there need to be ASICs supporting the flow sampling. Reference.
