Configuring the refresh rate for NetStream version 9 templates

Version 9 is template-based and supports user-defined formats, so the NetStream-enabled device needs
to resend a new template to the NetStream server for an update. If the version 9 format is changed on the
NetStream-enabled device and is 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 NetStream version 9 templates:
Step
1. Enter system view.
2. Configure the refresh frequency
for NetStream version 9
templates.
3. Configure the refresh interval
for NetStream version 9
templates.

Configuring MPLS-aware NetStream

An MPLS flow is identified by the same labels in the same position and the same 7-tuple elements.
MPLS-aware NetStream collects and exports statistics on labels (up to three) in the label stack, FEC
corresponding to the top label, and traditional 7-tuple elements data.
To configure MPLS-aware NetStream:
Step
1. Enter system view.
2. Count and export
statistics on MPLS
packets.

Configuring NetStream flow aging

Flow aging approaches

The following types of NetStream flow aging are available:
Periodical aging
•
Command
system-view
ip netstream export v9-template
refresh-rate packet packets
ip netstream export v9-template
refresh-rate time minutes
Command
system-view
ip netstream mpls [ label-positions
{ label-position1 [ label-position2 ]
[ label-position3 ] } ] [ no-ip-fields ]
97
Remarks
N/A
Optional.
By default, the version 9 templates
are sent every 20 packets.
Optional.
By default, the version 9 templates
are sent every 30 minutes.
Remarks
N/A
By default, no statistics about MPLS
packets are counted and exported.
The command of ip netstream mpls
[ label-positions { label-position1
[ label-position2 ]
[ label-position3 ] } ] [ no-ip-fields ]
enables both IPv4 and IPv6
NetStream of MPLS packets.
