(Optional) Configuring NetStream Monitoring Services
NetStream monitoring services can be configured on the NetStream Data Exporter (NDE), which enables carriers to implement more delicate traffic statistics and management over IPv4 original flows.
Context
Increasing types of services and applications on networks urge carriers to provide more delicate management and accounting services.
If NetStream is configured on multiple interfaces on an NDE, all interfaces send traffic statistics to a single NetStream Collector (NSC). The NSC cannot distinguish interfaces, and therefore, cannot manage or analyze traffic statistics based on interfaces. In addition, the NSC will be overloaded due to a great amount of information.
NetStream monitoring configured on an NDE allows the NDE to send traffic statistics collected on specified interfaces to specified NSCs for analysis, which achieves interface-specific service monitoring. Traffic statistics can be balanced among these NSCs.
Procedure
- Run system-view
The system view is displayed.
- Run ip netstream monitor monitor-name
A NetStream monitoring service is created and its view is displayed. If a NetStream monitoring service view already exists, the view is displayed.
- (Optional) Run ip netstream export source { ip-address | ipv6 ipv6-address } [ port ]
A source IP address and a source port are configured for output NetStream flows.
- Run ip netstream export host [ ipv6 ] ip-address port [ vpn-instance vpn-instance-name ] [ version { 5 | 9 | ipfix } ] [ dscp dscp-value ]
The destination IP address and destination port number for traffic statistics are specified.
- Run quit
Return to the system view.
- Run interface interface-type interface-number
The interface view is displayed.
- Run ip netstream monitor monitor-name { inbound | outbound }
NetStream monitoring services are configured in the inbound or outbound direction of the interface.
If NetStream monitoring services have been configured on the interface, statistics about original flows are sent to the destination IP address specified in the NetStream monitoring service view, not the system view. The source address and source port configured in the NetStream monitoring service view are also used for output NetStream flows.
- Run commit
The configuration is committed.
