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 lists 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.

table, the statistics on the BGP next hop cannot be obtained.
IPv6 NetStream export format
the statistics on the AS number cannot be obtained.

IPv6 NetStream exports data in UDP datagrams in version 9 format.
