Example for Configuring Original Flow Statistics Exporting
Networking Requirements
In Figure 2-44, departments 1 and 2 connect to the Internet through SwitchA. Network administrators want to collect statistics about traffic between the two departments and the Internet for network planning.
A data center network of an enterprise is complex. To ensure security and stability of the network, the enterprise needs to monitor the network in real time and restrict login rights of the administrator. A network management system can meet the preceding requirements.
Configuration Roadmap
You can configure IPv4 original flow statistics exporting on 10GE1/0/1 of SwitchA. Configure SwitchA to collect statistics about incoming and outgoing traffic on the interface, and to send the statistics to the NetStream server for further analysis. The analysis result helps you plan the network.
The configuration roadmap is as follows:
- Configure IP addresses for interfaces on SwitchA.
- Configure NetStream sampling.
- Configure NetStream flow aging.
- Configure original flow statistics exporting.
- Configure the version for exported packets.
- Enable original flow statistics collection on interfaces.
Procedure
- Configure IP addresses for interfaces on SwitchA as shown in Figure 2-44.
# Assign IP addresses to the interfaces of SwitchA.
