Software version used This document describes the example for the H3C SecBlade NetStrearm cards (Release 3109) installed on the H3C S7500E switches. The configuration examples also apply to the H3C SecBlade NetStream cards installed on the H3C S9500E and S12500 switches. The configuration examples in this document were created and verified in a lab environment, and all the devices started with the factory default configuration. If you are working in a live network, make sure you understand the potential impact of every command on your network. Feature overview NetStream is an accounting technology that provides statistics on a per-flow basis. A flow is identified by the following elements: source IP address, destination IP address, source port number, destination port number, protocol number, ToS, and inbound or outbound interface. NetStream provides the statistics for different flows. A typical NetStream system comprises the following parts: NetStream data exporter (NDE) An H3C SecBlade NetStream card (NS card) with NetStream configured acts as an NDE. It analyzes traffic flows that pass through it, collects necessary data from the target flows, and exports the data to the NSC. Before exporting data, the NDE might perform processes on the data, such as aggregation. NetStream collector (NSC) The NSC parses the packets received from the NDE, stores the statistics to the database, and then filters and aggregates the total received data for the NDA. NetStream data analyzer (NDA) The NDA collects statistics from the NSC, performs further process, and generates various types of reports for applications of traffic billing, network planning. H3C IMC-NTA, which supports both NSC and NDA, gathers the data from the NS card and generates reports. Configurations for NetStream involve configurations for the switch, the NS card, and IMC-NTA. The NS card can be installed on the H3C S7500E, S9500E, and S12500 switch. This document uses S7500E as an example, and explains the NS card configuration differences between the S7500E switches and S9500E/S12500 switches. Application scenarios NetStream provides statistics about network traffic flows, and it can be deployed on access, distribution, and core layers. Configuration considerations Configure S7500E to mirror the traffic accounted by NetStream to the 10-GE interface connecting the NS card. Configure the NS card to account the traffic copied to the interface Ten-GigabitEthernet 0/0 and send it to the NSC for analyzing. 1
Configure protocol-port aggregation. (Optional.) Configure sampling. (Optional.) Configure the traffic analysis service on the NSC server (IMC-NTA) to account the traffic statistics received from the NS card. IPv4 NetStream configuration example Network requirements As shown in Figure 1, install an NS card in slot 4 of the switch to collect statistics on packets passing through it, and mirror the intranet-to-extranet traffic from source IP addresses belonging to the subnet 10.1.0.0/16 to the NS card for flow analyzing. GigabitEthernet 2/0/1 and GigabitEthernet 2/0/2 on the switch are access ports, and belong to VLAN 10 (the intranet VLAN) and VLAN 20 (the extranet VLAN), respectively. Ten-GigabitEthernet 4/0/1 on the switch is a trunk port and allows packets from all VLANs to pass through. Configure traffic mirroring on GigabitEthernet 2/0/1 to mirror the incoming traffic to Ten-GigabitEthernet 4/0/1. Enable NetStream on Ten-GigabitEthernet 0/0 on the NS card. The statistics on the NS card are sent out of the management interface GigabitEthernet 0/1 to the NSC for analyzing.

Both the S9500E switches and S12500 switches support the mirroring and sampling features, so sampling is implemented on the switch side. Disable sampling on the NS card (enabled by default), and configure a sampler with the same sampling interval as the switch. Apply the sampler to the Ten-GigabitEthernet interface for sampling. The following describes the configuration differences between S9500E + NetStream and S7500E + NetStream. Configurations on S12500 + NetStream are the same as those on S9500E+ NetStream.

Configuring NSC server (IMC-NTA) For the IMC-NTA server, configurations for IPv6 traffic analysis tasks are the same as IPv4 traffic analysis tasks. Therefore, they are not described here. See "Configuring NSC server (IMC-NTA)." Verifying the configuration Connect port-a and port-b of Smartbits to GigabitEthernet 2/0/1 and Gigabit Ethernet 2/0/2 on the S7500E switch, respectively. Port-a sends UDP packets with the source IP 10:1::2 and destination IP 20.1::2. View the following information through IMC-NTA: Whole statistics on all traffic analysis tasks Click the Service tab, and select Traffic Analysis and Audit > Interface Traffic Analysis Task from the navigation tree to view the whole statistics on all traffic analysis tasks, including average rate and summary list. Figure 27 Average rate Figure 28 Summary list Whole statistics on all interfaces for a traffic analysis task Select Traffic Analysis and Audit > SecBlade NS to view the whole statistics on all interfaces for a traffic analysis task, including information about traffic, application, source host, destination host, and sessions. "Traffic" includes pages for traffic trend, flux distribution in interface, and traffic details. 26
Figure 29 Traffic trend Figure 30 Traffic details "Application" displays information about the application layer traffic, and includes pages for application list and application traffic trend. Figure 31 Application list 27
"Source host" displays traffic information based on IP address for the source host. Figure 32 Traffic information for source host "Destination host" displays information based on IP address for the destination host. Figure 33 Traffic information for destination host "Session" displays traffic information based on sessions. 28
Figure 34 Traffic information for session host Statistics on every host for a traffic analysis task Complete configuration Select the interface on the SecBlade NS list to view the corresponding statistics on that interface. You can view the same information about traffic, application, source host, destination host and session host as the traffic analysis task information. Therefore, it is not described and illustrated here. 1.
