Hi,

This switch supports Flexible Netflow, which config guidelines are explained here:

Kind Regards,

One more observation i found, In config terminal ip flow ingress & ip flow ingress layer2-switched are not available. I have enabled IP ROUTING in the global confguration.

Pandian / Sankar,

You need to use Flexible NetFlow on the new Cisco 4500 series. But the error you get with associating the ip flow monitor is a bug on the Cisco 4500. We have the details in our below blog:
