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 the refresh rate for IPv6 NetStream version 9
templates
Version 9 is template-based and supports user-defined formats, so the NetStream device needs to resend
a 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 cannot associate the received
statistics with its proper fields. To avoid this situation, configure the refresh frequency and rate for version
9 templates so that the NetStream server can refresh the templates on time.
The refresh frequency and interval can be both configured, and the template is resent when either of the
condition is reached.

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.
Configuring IPv6 NetStream flow aging
Flow aging methods
The following types of IPv6 NetStream flow aging are available:
• Periodical aging
• Forced aging
• TCP FIN- and RST-triggered aging (a
utomatically triggered if a TCP connection is terminated)
Periodical aging
Periodical aging uses the following methods:
