Step Command Remarks
2. Configure the version for
IPv6 NetStream export
format, and specify whether
to record AS and BGP next
hop information.
ipv6 netstream export version 9
[ origin-as | peer-as ] [ bgp-nexthop ]
Optional.
By default, version 9 format is
used to export IPv6 NetStream
traditional data, IPv6 NetStream
aggregation data, and MPLS flow
data with IPv6 fields; the peer AS
numbers are recorded; the BGP
next hop is not recorded.
Configuring refresh rate for IPv6 NetStream version 9
templates
Version 9 is template-based and supports user-defined formats, so the NetStream-enabled router needs
to resend the new template to the NetStream server for an update. If the version 9 format is changed on
the router and not updated on the NetStream server, the server is unable to associate the received
statistics with its proper fields. To avoid such situation, configure the refresh frequency and rate for version
9 templates so that the NetStream server can refresh the templates on time.
To configure the refresh rate for IPv6 NetStream version 9 templates:
Step Command Remarks
1. Enter system view. system-view N/A
2. Configure the refresh frequency
for NetStream version 9
templates.
ipv6 netstream export
v9-template refresh-rate packet
packets
Optional.
By default, the version 9 templates
are sent every 20 packets.
3. Configure the refresh interval for
NetStream version 9 templates.
ipv6 netstream export
v9-template refresh-rate time
minutes
Optional.
By default, the version 9 templates
are sent every 30 minutes.
NOTE:
The refresh frequency and interval can be both configured, and the template is resent when either of the
condition is reached.
Configuring MPLS-aware NetStream
Introduction to MPLS-aware NetStream
When you configure MPLS-aware NetStream, you can set whether to collect and export statistics about
the three labels of MPLS packets. For MPLS packets that carry IP data, NetStream records statistics on
labels (up to three) in the label stack, forwarding equivalent class (FEC) corresponding to the top label,
and the traditional 7-tuple elements data.
