Predefined user roles

network-admin

Parameters

ip-address: Specifies the destination IP address.

udp-port: Specifies the destination UDP port number in the range of 0 to 65535.

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance to which the destination host belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters. If the destination is on the public network, do not specify this option.

Usage guidelines

Parameters

rate: Specifies the export rate in the range of 1 to 1000.

Usage guidelines

This command sets the maximum number of NetStream packets that can be exported per second. Packets that cannot be exported due to the export rate limit are buffered for later export. When the buffer is full, the system will temporarily invalidate the rate limit and export packets as fast as possible until the buffer has space for new packets.

Examples

# Allow a maximum of 10 packets to be exported per second.

<Sysname> system-view

[Sysname] ip netstream export rate 10

ip netstream export source

Use ip netstream export source to specify the source interface for data packets sent to NetStream servers.

Use undo ip netstream export source to restore the default.

Default

The packets take the IP address of the output interface as the source IP address.

Views

Parameters

interface-type interface-number: Specifies a source interface by its type and number.

Usage guidelines

The IP address of the specified source interface is used as the source IP address for packets sent to NetStream servers.

ip netstream export template refresh-rate

Use ip netstream export template refresh-rate to set the refresh rate for the NetStream version 9 or version 10 template.

Use undo ip netstream export template refresh-rate to restore the default.

Syntax

ip netstream export template refresh-rate { packet packets | time minutes }

undo ip netstream export template refresh-rate { packet | time }

Default

The packet count-based refresh rate is 20 packets, and the time-based refresh interval is 30 minutes.

Views

System view

Predefined user roles

network-admin

Parameters

packets: Specifies the number of packets that are sent before the template is sent. The value range is 1 to 600.

time minutes: Specifies the interval at which the template is sent, in the range of 1 to 3600 minutes.

Usage guidelines

Version 9 and version 10 are template-based and support user-defined formats. A NetStream device must send the version 9 or version 10 template to NetStream servers regularly, because the servers do not permanently save the templates.

The refresh rate can be packet count-based or time-based. If both settings are configured, the template is sent when either of the conditions is met.

Examples

# Configure the device to send the Netstream version 9 or version 10 template to NetStream servers every 100 packets.

<Sysname> system-view

[Sysname] ip netstream export template refresh-rate packet 100

ip netstream export version

Use ip netstream export version 5 to export NetStream data in the version 5 format and choose whether to record AS information.

Use ip netstream export version 9 to export NetStream data in the version 9 format and choose whether to record AS and BGP next hop information.

Use ip netstream export version 10 to export NetStream data in the version 10 format and choose whether to record AS and BGP next hop information.

Use undo ip netstream export version to restore the default.

Syntax

ip netstream export version 5 { origin-as | peer-as }

ip netstream export version { 9 | 10 } { origin-as | peer-as } [ bgp-nexthop ]

undo ip netstream export version

Default

NetStream traditional data export uses the version 9 format. The peer AS numbers are exported. The BGP next hop is not recorded.

Views

System view

Predefined user roles

network-admin

Parameters

origin-as: Records the source AS of the source address and the destination AS of the destination address.

peer-as: Records the ASs before and after the AS where the NetStream device resides as the source AS and destination AS, respectively.

bgp-nexthop: Records BGP next hops.

Usage guidelines

A NetStream entry records the source IP address and destination IP address, and two AS numbers for each IP address. You can choose to configure which AS numbers are to be exported as the source AS and destination AS.

Only version 9 and version 10 formats support recoding BGP next hop data.

Only one version format can take effect on the device. If you execute the command multiple times, the most recent configuration takes effect.

Examples

# Configure the device to export NetStream data in the version 5 format and specify the NetStream data to include the source AS and destination AS.

<Sysname> system-view

[Sysname] ip netstream export version 5 origin-as

ip netstream sampler

Use ip netstream sampler to enable NetStream sampling.

Use undo ip netstream sampler to disable NetStream sampling.

Syntax

ip netstream { inbound | outbound } sampler sampler-name

undo ip netstream { inbound | outbound } sampler

Default

NetStream sampling is disabled.

Views

Interface view

Predefined user roles

network-admin

Parameters

inbound: Enables NetStream sampling in the inbound direction.

outbound: Enables NetStream sampling in the outbound direction.

sampler sampler-name: Specifies a sampler by its name. The name is a case-insensitive string of 1 to 31 characters.

Usage guidelines

By default, NetStream collects all data of target flows. If the flow traffic is heavy, NetStream is resource-consuming and can cause high CPU usage, which impacts the device forwarding performance. NetStream sampling is helpful to decrease the NetStream traffic volume. If the collected statistics can basically reflect the network status, you can enable this feature and set a proper sampling rate. The higher the sampling rate, the less impact on device performance.

Examples

# Use sampler abc for inbound NetStream sampling on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] ip netstream inbound
