Table 51-4 shows the default NDE configuration.
NDE Configuration Guidelines and Restrictions
When configuring NDE, follow these guidelines and restrictions:
• NDE supports IP multicast traffic only with NetFlow version 9.
• NetFlow aggregation must use NDE version 8 or version 9.
• In PFC3B or PFC3BXL mode with Release 12.2(18)SXE and later releases, NDE supports bridged
IP traffic. PFC3A mode does not support NDE for bridged IP traffic.
• NDE does not support Internetwork Packet Exchange (IPX) traffic or any other non-IP protocol.
Configuring NDE
These sections describe how to configure NDE:
• Configuring NDE on the PFC, page 51-11
• Configuring NDE on the MSFC, page 51-13
• Enabling NDE for Ingress-Bridged IP Traffic, page 51-15
• Displaying the NDE Address and Port Configuration, page 51-15
• Configuring NDE Flow Filters, page 51-16
• Displaying the NDE Configuration, page 51-18
Note • You must enable NetFlow on the MSFC Layer 3 interfaces to support NDE on the PFC and NDE on
the MSFC.
• You must enable NDE on the MSFC to support NDE on the PFC.
• When you configure NAT and NDE on an interface, the PFC sends all fragmented packets to the
MSFC to be processed in software. (CSCdz51590)
