Hello Aruldaspr,

on a C6509 you need to configure also NDE export because it is a multilayer switch and real traffic is processed by PFC

see

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SXF/native/configuration/guide/nde.html#wp1140493

Additional NDE Fields

You can configure NDE to populate the following additional fields in the NDE packets:

•IP address of the next hop router

•Egress interface SNMP ifIndex

•BGP AS

Hope to help

Giuseppe
