what the prob if we can't see flow from netflow enabled devices?
I've enabled netflow on sevral switches. out of which I cannot see flow from couple of switches. I checked all config, cpu statistics, flow statistics, show ip flow export & sh ip cache flow, but evrything seems right.
what may be the reason I cannot see flow from few switches.??????
I checked firewall & accesslist, but nothing is there which is blocking that devices..

The box certainly is certainly exporting netflow traffic:
14911 flows exported in 4156 udp datagrams
So check that the collector address 10.152.4.48 is reachable from here, and verify whether the collector address or port (2003) is being firewalled somewhere along the way (eg, at an intermediate node).
You might want to put a traffic sniffer on your wire to verify where netflow export packets are seen.
