Configure the version for IPv6
NetStream export format ipv6 netstream export
version 9
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.
Configuring refresh rate for IPv6 NetStream version 9
templates
Version 9 is template-based, so the NetStream device needs to resend the new template to the NetStream
server for an update. If the version 9 format is changed on the NetStream device 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.
Follow these steps to configure the refresh rate for IPv6 NetStream version 9 templates:
To do… Use the command… Remarks
Enter system view system-view —
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.
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.
