I cannot find it stated explicitly, but it appears netflow is not supported in FWSMs.
This is a major drawback for an organisation who depends on netflow. We have a very large switched network connected by several 6513s, as we migrate subnets to the FWSMs in each, we lose visibility of network traffic.
Is anyone aware of plans to support netflow in future software releases or are there are ideas for workarounds?
cheers,
