Configuring the refresh rate for NetStream version 9 templates

Version 9 is template-based and supports formats that can be defined, 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 the refresh interval for version 9 templates so that the NetStream server can refresh the

templates on time.
The refresh frequency and the refresh interval can be both configured, and the template is resent when

either of the conditions is reached.
To configure the refresh rate for 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.

ip netstream export v9-template
refresh-rate packet packets

By default, the version 9 templates
are sent every 20 packets.

3.

Configure the refresh interval

for NetStream version 9
templates.

ip netstream export v9-template
refresh-rate time minutes

By default, the version 9 templates
are sent every 30 minutes.

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, depending on your configuration, traditional 7-tuple elements data.
To configure MPLS-aware NetStream:

Step Command

Remarks

1.

Enter system view.

system-view

N/A

2.

Collect and export
statistics on MPLS

packets.

ip netstream mpls [ label-positions
label-position1 [ label-position2
[ label-position3 ] ] ] [ no-ip-fields ]

By default, no statistics about MPLS
packets are collected and exported.
