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:
Original flow statistics are exported when the flow aging time expires. Statistics on every flow are exported to the NetStream server. The NetStream server obtains detailed statistics on every flow.
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.
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, and perform accounting for each department.
You can configure IPv4 original 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, and perform accounting for each department.
The configuration roadmap is as follows:
# Configure IP addresses for interfaces on SwitchA.
