Usage guidelines

The types of NetStream entries for flow packets vary by the export template version and whether the flow packets contain IP headers.

· If the version 9 template is used:

¡ The type of the NetStream entry is ipl2 (Layer 2 and Layer 3) for flow packets containing IP headers.

¡ The type of the Netstream entry is l2 (Layer 2) for flow packets without IP headers.

· If the version 5 template is used:

¡ The type of the NetStream entry is ip (Layer 3) for flow packets containing IP headers.

¡ The type of the NetStream entry is l2 (Layer 2) for flow packets without IP headers.

Usage guidelines

This feature enables local archiving of cached NetStream entries when they are exported to NetStream servers.

You can display the locally archived NetStream entries by using the display ip netstream cache archive command.

This feature is applicable when a small number of NetStream entries exist and no log server exists. If the device generates a large number of NetStream entries, do not enable this feature. Otherwise, the device performance will be affected.

Examples

# Enable archiving of cached NetStream entries.

ip netstream export host

Use ip netstream export host to specify a destination host for NetStream data export.

Use undo ip netstream export host to remove the specified destination host or all destination hosts that are configured in the current view.

Syntax

undo ip netstream export host [ ip-address [ vpn-instance vpn-instance-name ] ]

Default

No destination host is specified.

Views

System view

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

You can specify the same destination IP address and UDP port in different NetStream aggregation mode views. If an aggregation mode is not enabled, the display ip netstream export command cannot display the destination host configuration for the mode.

If no destination host is specified in a NetStream aggregation mode view, the destination host in system view applies. If destination hosts are specified in a NetStream aggregation view and system view, the destination hosts in aggregation view take effect.

You can specify a maximum of four destination hosts in system view or a NetStream aggregation mode view. If you specify a destination host with the same IP address but different UDP ports in the same view, the most recent configuration takes effect. You can specify destination hosts with the same IP address and UDP port but different VPN instances.

NetStream traditional data is exported to all destination hosts in system view. NetStream aggregation data is exported to all destination hosts in the related NetStream aggregation mode view. If you expect only the aggregation data, specify destination hosts only in the NetStream aggregation mode view. Aggregation data export reduces bandwidth usage.

Examples

# In system view, specify 172.16.105.48 as the IP address of the destination host and UDP port 5000 as the export destination port number.

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.

You can configure different source interfaces in different NetStream aggregation mode views.

If no source interface is configured in a NetStream aggregation mode view, the source interface in system view applies.

ip netstream export v9-template refresh-rate

Use ip netstream export v9-template refresh-rate to set the refresh rate for the NetStream version 9 template.

Use undo ip netstream export v9-template refresh-rate to restore the default.

Syntax

ip netstream export v9-template refresh-rate { packet packets | time minutes }

undo ip netstream export v9-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 is template-based and supports user-defined formats. A NetStream device must send the version 9 template to NetStream servers regularly, because the servers do not permanently save the template.

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 template to NetStream servers every 100 packets.

<Sysname> system-view

[Sysname] ip netstream export v9-template refresh-rate packet 100

ip netstream export version

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 { 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.

Recoding BGP next hop data is supported only by the version 9 format.

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.

Predefined user roles

network-admin

Parameters

inbound: Filters incoming traffic.

outbound: Filters outgoing traffic.

acl ipv4-acl-number: Specifies an IPv4 ACL by its number. The value range is 2000 to 2999 for basic ACLs, 3000 to 3999 for advanced ACLs, and 4000 to 4999 for Layer 2 ACLs.

Usage guidelines

NetStream filtering uses an ACL to identify intended packets.

· If you want to collect data for specific flows, use the ACL permit statements to identify the flows. NetStream collects data only for these flows.

· If you do not want to collect data for specific flows, use the ACL deny statements to identify the flows. NetStream does not collect data for these flows.

ip netstream sampler

Use ip netstream sampler to enable NetStream sampling.

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.

If you configure this command without specifying a traffic direction, NetStream sampling is enabled on the interface for both inbound and outbound traffic.

Examples

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