Outputting Aggregated Flows
To ensure that aggregated flows are correctly output to the NMS, configure the aging time, source address, and destination address for aggregated flows.
Procedure
- Run system-view
The system view is displayed.
- Run ipv6 netstream export host ip-address port [ vpn-instance vpn-instance-name ] [ dscp dscp-value ]
The destination IP address and destination port number for traffic statistics are specified.
The destination IP address specified in the system view takes precedence over that specified in the NetStream aggregation view.
- Run ipv6 netstream aggregation { as | as-tos | bgp-nexthop-tos | destination-prefix | destination-prefix-tos | index-tos | mpls-label | prefix | prefix-tos | protocol-port | protocol-port-tos | source-prefix | source-prefix-tos | vlan-id }
The IPv6 NetStream aggregation view is displayed.
- Run enable
The NetStream aggregation mode is enabled.
- (Optional) Run template timeout-rate timeout-interval
The interval at which the template for outputting aggregated flows in the V9 or IPFIX format is refreshed is set.
- Run ipv6 netstream export source { ip-address | ipv6 ipv6-address } [ port ]
The source IP address and source port are specified for aggregated flows.
The source IP address and source port specified in the aggregation view take precedence over those specified in the system view. If no source IP address or source port is specified in the aggregation view, the source IP address and source port specified in the system view take effect.
- Run ipv6 netstream export host [ ipv6 ] ip-address port [ vpn-instance vpn-instance-name ] [ dscp dscp-value ]
The destination IP address and the UDP port number of the peer NSC are specified for traffic statistics export.
You can specify eight destination IP addresses in the system view, IPv4 NetStream aggregation view, and IPv4 NetStream aggregation view.
The destination IP address specified in the system view takes precedence over that specified in the NetStream aggregation view.
- Run quit
Return to the system view.
- (Optional) Set parameters for aging aggregated flows as needed.
- Run ipv6 netstream aggregation timeout active { active-interval | interval-second active-interval-second }
The active aging time of NetStream aggregated flows is set.
Run ipv6 netstream aggregation timeout inactive inactive-interval
The inactive aging time is set for NetStream aggregated flows.
- Run ipv6 netstream aggregation timeout active { active-interval | interval-second active-interval-second }
- (Optional) Exit the IPv6 aggregated configuration mode view. In the system view, run ipv6 netstream export template sequence-number fixed
The sequence numbers of template packets and option template packets in IPFIX format are configured to remain unchanged, but data packets and option data packets in IPFIX format are still consecutively numbered.
- Run commit
The configuration is committed.
