Example for Configuring IPv4 Flexible Flow Statistics Exporting
Networking Requirements
In Figure 11-14, departments 1 and 2 connect to the Internet through SwitchA. Network administrators want to monitor communication between departments and the Internet.
Configuration Roadmap
To monitor communication between the departments and the Internet, the network administrator needs to:
- Configure IPv4 flexible flow statistics exporting on GE1/0/1 of SwitchA.
- Collect statistics about incoming and outgoing traffic on the interface.
- Send statistics to the NetStream server for further analysis.
The configuration roadmap is as follows:
- Configure IP addresses for interfaces on SwitchA.
- Configure a flexible flow statistics template.
- Configure NetStream flexible flow statistics exporting.
- Enable flexible flow statistics collection on the interface.
Procedure
- Configure IP addresses for interfaces on SwitchA as shown in Figure 11-14.
# Configure IP addresses for interfaces on SwitchA.

- Configure a flexible flow statistics template.
# Create a flexible flow statistics template named test, configure aggregation based on the destination IP address and destination port number, configure the number of bytes and packets in the exported packets, and configure the indexes of the inbound and outbound interfaces.

- Configure exporting of NetStream flexible flow statistics.
# Set the source IP address of the exported packets carrying flexible flow statistics to 10.1.2.1, the destination IP address to 10.1.2.2, and the destination port number to 6000.
[SwitchA] ip netstream export source 10.1.2.1 [SwitchA] ip netstream export host 10.1.2.2 6000
- Enable NetStream flexible flow statistics collection on the interface.
# Enable flexible flow statistics exporting on GE1/0/1, and apply the flexible flow statistics template test to GE1/0/1.

- Verify the configuration.
# After the configuration is complete, the NetStream server receives the statistics packets from the device. Run the display ip netstream statistics command on the local device to view NetStream statistics.
