Usage guidelines

The hardware aggregation does not take effect in the following situations:

· The destination host is configured for the NetStream traditional data export in system view.

· The aggregation mode set by the ip netstream aggregation command is not supported by NetStream hardware aggregation.

The NetStream hardware aggregation entries are stored in the same cache as NetStream traditional data entries and are exportable.

· ip netstream aggregation

· ip netstream export host

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

ip netstream export host ip-address udp-port [ vpn-instance vpn-instance-name ]

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

Default

No destination host is specified.

Views

System view, NetStream aggregation mode view

Predefined user roles

network-admin

mdc-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 host in different NetStream aggregation mode views.

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 addresses but different UDP ports, 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 are exported to all destination hosts in system view. NetStream aggregation data are exported to all destination hosts in the related NetStream aggregation mode view.

If you expect only the aggregation data, you can specify destination hosts only in the NetStream aggregation mode view. This setting 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.

<Sysname> system-view

[Sysname] ip netstream export host 172.16.105.48 5000

# In destination-prefix aggregation mode view, specify 172.16.105.50 as the IP address of the destination host and UDP port 6000 as the export destination port number.

Use undo ip netstream export source to remove the configuration.

Syntax

ip netstream export source interface interface-type interface-number

undo ip netstream export source

Parameters

packets: Specifies the number of packets that are sent before version 9 templates are sent to NetStream servers for an update. The value range is 1 to 600.

Usage guidelines

A NetStream server uses version 9 templates to parse the data from the NetStream device, but the server does not permanently save version 9 templates.

For a NetStream server to use correct version 9 templates, configure the refresh frequency or refresh interval for version 9 templates. If both settings are configured, templates are sent when either of the conditions is reached.

To configure the refresh interval for version 9 templates, use the ip netstream export v9-template refresh-rate time command.

Examples

# Configure the device to send version 9 templates to NetStream servers every 100 packets.

<Sysname> system-view

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

Related commands

ip netstream export v9-template refresh-rate time

Use ip netstream export v9-template refresh-rate time to configure the refresh interval for version 9 templates.

Use undo ip netstream export version to restore the default.

Syntax

Parameters

minutes: Specifies the refresh interval in the range of 1 to 3600 minutes.

Usage guidelines

A NetStream server uses version 9 templates to parse the data from the NetStream device, but the server does not permanently save version 9 templates.

To configure the refresh frequency for version 9 templates, use the ip netstream export v9-template refresh-rate packet command.

Examples

# Configure the device to send version 9 templates every 60 minutes.

ip netstream export version

Use ip netstream export version 5 to export NetStream data in the version 5 format and choose whether or not 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 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 exported.

Views

System view

Predefined user roles

network-admin

mdc-admin

Parameters

origin-as: Exports statistics of the source AS originating the route for the source address and the destination AS for the destination address.

peer-as: Exports statistics of the peer ASs for the source and destination address.

bgp-nexthop: Exports statistics of BGP next hops.

Usage guidelines

A NetStream entry for a flow 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.

If the version 5 format is configured to export NetStream data, the NetStream aggregation data export uses the version 8 format.

If the version 9 format is configured to export NetStream data, the NetStream aggregation data export uses the version 9 format.

Statistics of BGP next hop can be exported only in the version 9 format.

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 to specify the NetStream data to include the source AS and destination AS.
