Configuring NDE
•
This example shows how to configure a loopback interface as the NDE flow source:
Router(config)# ip flow-export source loopback 0
Router(config)#
Configuring the NDE Destination
To configure the destination IP address and UDP port to receive the NDE statistics, perform this task:
Command
Router(config)# ip flow-export destination ip_address
udp_port_number
Router(config)# no ip flow-export destination
ip_address udp_port_number
NetFlow Multiple Export Destinations—To configure redundant NDE data streams, which improves the
Note
probability of receiving complete NetFlow data, you can enter the ip flow-export destination command
twice and configure a different destination IP address in each command. This hardware and these
releases support the NetFlow Multiple Export Destinations feature:
•
•
Note that configuring two destinations increases the RP CPU utilization, as you are exporting the data
records twice.
This example shows how to configure the NDE flow destination IP address and UDP port:
Router(config)# ip flow-export destination 172.20.52.37 200
The destination address and UDP port number are saved in NVRAM and are preserved if NDE is
Note
disabled and reenabled or if the router is power cycled. If you are using the NetFlow FlowCollector
application for data collection, verify that the UDP port number you configure is the same port number
shown in the FlowCollector's /opt/csconfc/config/nfconfig.file file.
Configuring Netflow Flow Sampling
In 12.2(18)SXF and later releases, the MSFC supports NetFlow sampling for software-routed traffic.
