Example for Configuring IPv4 Original Flow Statistics Exporting
Networking Requirements
In Figure 11-12, departments 1 and 2 connect to the Internet through SwitchA. Network administrators want to monitor communication between departments and the Internet, and perform accounting based on the department.
Configuration Roadmap
To monitor communication between the departments and the Internet, the network administrator needs to:
- Configure IPv4 original 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 NetStream sampling.
- Configure NetStream flow aging.
- Configure NetStream original flow statistics exporting.
- Configure the version for exported packets.
- Enable flow statistics collection on the interface.
Procedure
- Configure IP addresses for interfaces on SwitchA as shown in Figure 11-12.
# Configure IP addresses for interfaces on SwitchA.

- Configure NetStream sampling.
# Configure NetStream sampling on GE1/0/1, set the sampling ratio to 1200.

- Configure NetStream flow aging.
# Set the inactive aging time to 100 seconds and enable FIN- and RST-based aging.
[SwitchA] ip netstream timeout inactive 100 [SwitchA] ip netstream tcp-flag enable
- Configure exporting of NetStream original flow statistics.
# Set the source IP address of the exported packets carrying original 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
- Configure the version for exported packets.
# Set the version of the exported packets to V9.
[SwitchA] ip netstream export version 9 - Enable flow statistics collection on the interface.
# Enable flow statistics on GE1/0/1 for incoming and outgoing packets.
[SwitchA] interface gigabitethernet 1/0/1 [SwitchA-GigabitEthernet1/0/1] ip netstream inbound [SwitchA-GigabitEthernet1/0/1] ip netstream outbound [SwitchA-GigabitEthernet1/0/1] quit [SwitchA] quit
- 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.
