NOTE:
•
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.
Version 9 format is the most flexible format. Its template-based feature provides support of different
statistics information, such as BGP next hop and MPLS information.
IPv6 NetStream configuration task list
Before configuring IPv6 NetStream, determine proper configurations as needed.
•
Make sure on which router you want to enable IPv6 NetStream, that is, the NDE.
•
If multiple service flows are passing the NDE, use an ACL or QoS policy to select the target data.
•
Determine which export format is used for IPv6 NetStream data export.
•
Configure the timer for IPv6 NetStream flow aging.
•
To reduce the bandwidth consumption used by IPv6 NetStream data export, configure IPv6
NetStream aggregation.
