IPv6 NetStream aggregation data export
IPv6 NetStream aggregation merges the flow statistics according to the aggregation criteria of an
aggregation mode, and it sends the summarized data to the IPv6 NetStream server. This process is the
IPv6 NetStream aggregation data export, which uses less bandwidth than traditional data export.
Table 12 li
sts the six IPv6 NetStream aggregation modes are supported. In each mode, the system
merges flows into one aggregation flow if the aggregation criteria are of the same value. These six
aggregation modes work independently and can be configured on the same interface.

AS aggregation
• Source AS number
• Destination AS number
• Inbound interface index
• Outbound interface index
Protocol-port aggregation
• Protocol number
• Source port
• Destination port
Source-prefix aggregation
• Source AS number
• Source address mask length
• Source prefix
• Inbound interface index
Destination-prefix aggregation
• Destination AS number
• Destination address mask length
• Destination prefix
• Outbound interface index
Prefix aggregation
• Source AS number
• Destination AS number
• Source address mask length
• Destination address mask length
• Source prefix
• Destination prefix
• Inbound interface index
• Outbound interface index
BGP-nexthop
• BGP next hop
• Outbound interface index
In an aggregation mode with AS, if the packets are not forwarded according to the BGP routing table,
the statistics on the AS number cannot be obtained.
In the aggregation mode of BGP-nexthop, if the packets are not forwarded according to the BGP routing
table, the statistics on the BGP next hop cannot be obtained.
IPv6 NetStream export format
IPv6 NetStream exports data in UDP datagrams in version 9 format.
