This is because the packets are L3 switched in the hardware by the PFC.
Due to the CEF based architecture of the SUP2 / MSFC2, the MSFC2 processes
routing updates, creates FIB and ADj tables. These tables then get
downloaded to the PFC hardware so that it can do local CEF lookups. Sup2
also maintains the Netflow table to provide flow statistics.
Please refer to this document on configuring NDE to monitor L3 switched
traffic:
