Example for Configuring IPv4 Aggregation Flow Statistics Exporting

Networking Requirements

In Figure 1, departments 1 and 2 connect to the Internet through SwitchA. Network administrators want to monitor communication between departments and the Internet.

Figure 1 Example configuration of IPv4 aggregation flow statistics exporting

Configuration Roadmap

To monitor communication between the departments and the Internet, the network administrator needs to:

Configure IPv4 aggregation flow statistics exporting on GE0/0/1 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 aggregation 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 1.

# Configure IP addresses for interfaces on SwitchA.

Configure exporting of NetStream aggregation flow statistics.
# Configure protocol-port aggregation, and set the source IP address of the exported packets to 10.1.2.1, the destination IP address to 10.1.2.2, and the destination port number to 6000.
```
[SwitchA] ip netstream aggregation protocol-port
[SwitchA-aggregation-protport] ip netstream export source 10.1.2.1
[SwitchA-aggregation-protport] ip netstream export host 10.1.2.2 6000
[SwitchA-aggregation-protport] enable
```
Configure the version for exported packets.
# Set the version of the exported packets carrying aggregation flow statistics to V9.
```
[SwitchA-aggregation-protport] export version 9
[SwitchA-aggregation-protport] quit
```

Enable flow statistics collection on the interface.

# Enable flow statistics on GE0/0/1.

[SwitchA] interface gigabitEthernet 0/0/1
[SwitchA-GigabitEthernet0/0/1] ip netstream inbound
[SwitchA-GigabitEthernet0/0/1] ip netstream outbound
[SwitchA-GigabitEthernet0/0/1] quit
[SwitchA] quit

Verify the configuration.

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