Example for Configuring Aggregation Flow Statistics Exporting

NetStream Overview

NetStream is a technology that collects statistics on and analyzes service traffic on networks. NetStream facilitates accounting and network monitoring.

It has the following advantages:

NetStream collects statistics on multiple types of information in packets. It provides powerful statistics collection function and detailed statistical results.
NetStream can be deployed at a low cost. No dedicated device is required to collect traffic information and no device interface is occupied.

In aggregation flow statistics exporting, the device summarizes the flows with the same aggregation keywords, and obtains statistics on the aggregation flow. The aggregation flow statistics obviously reduce bandwidth occupation.

Configuration Notes

NetStream conflicts with IP Source Trail on modular switches, so do not configure them simultaneously.

For the applicable product models and versions of this example, see Applicable product models and versions.

Networking Requirements

As shown in Figure 1, Department 1 and Department 2 connect to the Internet through SwitchA. Network administrators want to monitor communication between the two departments and the Internet.

Figure 1 Networking diagram for configuring aggregation flow statistics exporting

Configuration Roadmap

You can configure IPv4 aggregation flow statistics exporting on GE1/0/1 of SwitchA. Configure SwitchA to collect statistics on incoming and outgoing traffic on the interface, and to send the statistics to the NetStream server for further analysis. In this way, you can monitor communication between the two departments and the Internet.

The configuration roadmap is as follows:

Configure IP addresses for interfaces on SwitchA.
Configure NetStream aggregation flow statistics exporting.
Configure the version of exported packets.
Enable NetStream flow statistics collection on GE1/0/1.

Procedure

Configure IP addresses for interfaces on SwitchA according to Figure 1.

# Configure IP addresses for interfaces on SwitchA.

Configure NetStream aggregation flow statistics exporting.
# Configure the aggregation keyword protocol-port, and set the source IP address of the exported packets to 10.1.2.1, destination IP address to 10.1.2.2, and 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 of 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 NetStream flow statistics collection on GE1/0/1.

# Enable NetStream flow statistics collection on GE1/0/1.

Verify the configuration.

# After the configuration is complete, the NetStream server can receive statistics packets from SwitchA. Run the display ip netstream statistics command on SwitchA to view NetStream flow statistics.
