Step Command

Remarks

Optional.
By default:

559.

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 ]

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.
To configure the refresh rate for IPv6 NetStream version 9 templates:

Step Command

Remarks

N/A

Optional.

561.

Configure the refresh
frequency for NetStream

version 9 templates.

ipv6 netstream export v9-template
refresh-rate packet packets

By default, the version 9 templates

are sent every 20 packets.

Optional.

562.

Configure the refresh
interval for NetStream

version 9 templates.

ipv6 netstream export v9-template
refresh-rate time minutes

By default, the version 9 templates

are sent every 30 minutes.

Configuring IPv6 NetStream flow aging

Flow aging approaches

The following types of IPv6 NetStream flow aging are available:

Periodical aging

Forced aging

TCP FIN- and RST-triggered aging

(automatically triggered if a TCP connection is terminated)

Periodical aging
